Answers

Answer 1

To determine whether the series ∑(n=2 to ∞) 6 / (n^2 - 1) is convergent or divergent, we can express the partial sums (sn) as a telescoping sum.

The telescoping sum method involves expressing each term in the series as a difference of two terms that cancel each other out when summed, leaving only a finite number of terms.

Let's express the terms of the series as a telescoping sum:

1. Write out the general term of the series:

a_n = 6 / (n^2 - 1)

2. Split the general term into two partial fractions:

a_n = 6 / [(n - 1)(n + 1)]

3. Express the general term as the difference of two terms:

a_n = (1/(n - 1)) - (1/(n + 1))

Now, let's calculate the partial sums (sn):

s_n = ∑(k=2 to n) [(1/(k - 1)) - (1/(k + 1))]

By telescoping, we can see that most terms will cancel out:

s_n = [(1/1) - (1/3)] + [(1/2) - (1/4)] + [(1/3) - (1/5)] + ... + [(1/(n-1)) - (1/(n+1))]

As we can observe, all terms cancel out except for the first and last terms:

s_n = 1 - (1/(n+1))

Now, let's analyze the behavior of the partial sums as n approaches infinity:

lim(n→∞) s_n = lim(n→∞) [1 - (1/(n+1))]

As n approaches infinity, the term 1/(n+1) approaches zero, resulting in:

lim(n→∞) s_n = 1 - 0 = 1

Since the limit of the partial sums (s_n) is a finite value (1), the series is convergent.

Therefore, the series ∑(n=2 to ∞) 6 / (n^2 - 1) is convergent.

Answers

The 90% confidence interval for the mean salary among graduates of University 1 is [2365.12, 2434.88] GBP.  the 90% confidence interval for the difference in mean salaries between University 1 and University 2 (₁-₂) is [-27.71, 227.71] GBP. a significant difference in mean salaries between the two universities at the 10% significance level.

(a) The 90% confidence interval for the mean salary among graduates of University 1 is [2365.12, 2434.88] GBP.

Therefore, the 90% confidence interval for the mean salary among graduates of University 1 is [2365.12, 2434.88] GBP.

(b) The 90% confidence interval for the difference in mean salaries between University 1 and University 2 (₁-₂) is [-27.71, 227.71] GBP.

Therefore, the 90% confidence interval for the difference in mean salaries between University 1 and University 2 (₁-₂) is [-27.71, 227.71] GBP.

(c) At the 10% significance level, we do not reject the null hypothesis that the mean salary is the same between the two universities.

To test the null hypothesis, we can use a two-sample t-test. The null hypothesis states that there is no significant difference between the mean salaries of graduates from University 1 and University 2.

The test involves the following steps:

State the null hypothesis (H0) and alternative hypothesis (H1).

Choose the significance level (α) as 0.10.

Find the critical value for the t-test at the given significance level and degrees of freedom.

Compare the calculated test statistic with the critical value.

If the calculated test statistic falls within the acceptance region, we do not reject the null hypothesis. Otherwise, we reject the null hypothesis.

In this case, the calculated test statistic does not fall outside the acceptance region, indicating that we do not reject the null hypothesis. Therefore, we conclude that there is not enough evidence to suggest a significant difference in mean salaries between the two universities at the 10% significance level.

(d) For this test to be valid, it is not required that the salary of each graduate in the two universities follows a normal distribution. The central limit theorem states that for a sufficiently large sample size, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution.

In this scenario, the sample sizes for both universities are 115 and 110, respectively, which can be considered sufficiently large for the central limit theorem to hold. As long as the assumptions for conducting a t-test are met (such as random sampling, independence, and approximately normal distribution), the validity of the test is preserved.

Hence, even if the salary distribution of each graduate does not follow a normal distribution, we can still rely on the validity of the statistical inference procedure used in this case, considering the sample sizes and assumptions are satisfied.

Suppose a sample of 1511 males and females were asked if they
feel tense or stressed out at work. The results are summarized in
the table:
Gender
Yes
No
Male
242
500
742
Female

Answers

Number of females who answered "No" = Total number of females - Number of females who answered "Yes"= Total number of females - 769

To complete the table, we need the missing value for the number of females who answered "Yes" to feeling tense or stressed out at work.

Given that the total sample size is 1511 and the data for males is already provided, we can calculate the missing value by subtracting the number of male "Yes" responses from the total number of "Yes" responses:

Total "Yes" responses = 742 (from the male column)

Total "No" responses = 500 (from the male column)

Total sample size = 1511

Number of females who answered "Yes" = Total "Yes" responses - Number of male "Yes" responses

= Total "Yes" responses - 742

Number of females who answered "Yes" = 1511 - 742

= 769

Now we can complete the table:

Gender | Yes | No | Total

Male | 242 | 500 | 742

Female | 769 | ??? | ???

Total | ??? | ??? | 1511

The missing value for the number of females who answered "No" can be calculated by subtracting the number of females who answered "Yes" from the total number of females:

Number of females who answered "No" = Total number of females - Number of females who answered "Yes"

= Total number of females - 769

Since we don't have the total number of females given in the question, we can't determine the exact value for the missing "No" response. Similarly, we cannot fill in the missing values for the total row since the total "Yes" and "No" responses are not given for the entire sample.

The correct choice is: OA. The equation has a solution in the interval [0°, 360°).  the equation using an algebraic method.

To solve the equation 13sin(θ) - 6sin(θ) = 5 in the interval [0°, 360°), we can use algebraic methods.

First, combine like terms on the left side of the equation:

13sin(θ) - 6sin(θ) = 5

(13 - 6)sin(θ) = 5

7sin(θ) = 5

Next, isolate sin(θ) by dividing both sides of the equation by 7:

sin(θ) = 5/7

Now, we need to find the values of θ in the given interval [0°, 360°) that satisfy this equation. To do that, we can take the inverse sine (or arcsine) of both sides of the equation:

θ = arcsin(5/7)

Using a calculator or a table of trigonometric values, we can find the value of arcsin(5/7) to be approximately 48.59°.

Answers

Answer : The marginal distribution of X is:fX(0) = (1/30)(f0 + f1 + f2 + f3)fX(1) = (1/30)(f1 + f2 + f3 + f4)fX(2) = (1/30)(f2 + f3 + f4 + f5)fX(3) = (1/30)(f3 + f4 + f5 + f6)

Explanation :

Given, f(xy) = 1/30 f (x + y) and x = 0, 1, 2, 3 and y = 0, 1, 2

a) Find the marginal distribution of Xi.e., P(X = i)

We can find the probability distribution function of Xi as follows:

fx(i) = ∑fxy(i, j)where ∑ is over all values of j.

So, we have:

fX(0) = f00 + f10 + f20 + f30 = (1/30)(f0 + f1 + f2 + f3)fX(1) = f01 + f11 + f21 + f31 = (1/30)(f1 + f2 + f3 + f4)fX(2) = f02 + f12 + f22 + f32 = (1/30)(f2 + f3 + f4 + f5)fX(3) = f03 + f13 + f23 + f33 = (1/30)(f3 + f4 + f5 + f6)

We need to find f(i, j) for all possible values of i and j.So, we have:

f00 = 1/30 (f0)f10 = 1/30 (f0 + f1)f20 = 1/30 (f0 + f1 + f2)f30 = 1/30 (f0 + f1 + f2 + f3)f01 = 1/30 (f0 + f1)f11 = 1/30 (f0 + f1 + f2 + f3)f21 = 1/30 (f1 + f2 + f3 + f4)f31 = 1/30 (f2 + f3 + f4 + f5)f02 = 1/30 (f0)f12 = 1/30 (f0 + f1 + f2)f22 = 1/30 (f1 + f2 + f3 + f4)f32 = 1/30 (f2 + f3 + f4 + f5)f03 = 1/30 (f0)f13 = 1/30 (f0 + f1)f23 = 1/30 (f1 + f2 + f3)f33 = 1/30 (f2 + f3)

Now, substitute the values of fxy into the above equations and simplify. fX(0) = (1/30)(f0 + f1 + f2 + f3)fX(1) = (1/30)(f1 + f2 + f3 + f4)fX(2) = (1/30)(f2 + f3 + f4 + f5)fX(3) = (1/30)(f3 + f4 + f5 + f6)

Therefore, the marginal distribution of X is:fX(0) = (1/30)(f0 + f1 + f2 + f3)fX(1) = (1/30)(f1 + f2 + f3 + f4)fX(2) = (1/30)(f2 + f3 + f4 + f5)fX(3) = (1/30)(f3 + f4 + f5 + f6)

the amount of time shoppers wait in line can be described by a continuous random variable, x, that is uniformly distributed from 4 to 15 minutes. calculate f(x).

Answers

The probability of waiting exactly 4 or 15 minutes is zero, since the uniform distribution is continuous and has no discrete values.

The amount of time shoppers wait in line can be described by a continuous random variable, x, that is uniformly distributed from 4 to 15 minutes.

Uniform distribution is a probability distribution, which describes that all values within a certain interval are equally likely to occur. The probability density function (PDF) of the uniform distribution is defined as follows: `f(x) = 1 / (b - a)` where `a` and `b` are the lower and upper limits of the interval, respectively.

Therefore, the probability density function of the uniform distribution for the given problem is `f(x) = 1 / (15 - 4) = 1 / 11`. Uniform distribution, also known as rectangular distribution, is a continuous probability distribution, where all values within a certain interval are equally likely to occur.

The probability density function of the uniform distribution is constant between the lower and upper limits of the interval and zero elsewhere.

Therefore, the PDF of the uniform distribution is defined as follows: `f(x) = 1 / (b - a)` where `a` and `b` are the lower and upper limits of the interval, respectively.

This formula represents a uniform distribution between `a` and `b`.In the given problem, the lower limit `a` is 4 minutes, and the upper limit `b` is 15 minutes.

Therefore, the probability density function of the uniform distribution is `f(x) = 1 / (15 - 4) = 1 / 11`.

This means that the probability of a shopper waiting between 4 and 15 minutes is equal to 1/11 or approximately 0.0909.

Answers

The sketch of the graph would be a U-shaped parabola with its vertex at the origin (0, 0) and the focus (0, 2/9) above the vertex, and the directrix y = -2/9 below the vertex.

To find the vertex, focus, and directrix of the given parabola, we first need to rewrite the equation in the standard form of a parabola. The standard form is given by [tex](x - h)^2 = 4a(y - k),[/tex] where (h, k) is the vertex and "a" determines the shape of the parabola.

Given equation: [tex]9x^2 - 8y = 0[/tex]

To rewrite it in standard form, we complete the square for the x-term:

[tex]9x^2 = 8y[/tex]

[tex]x^2 = (8/9)y[/tex]

Comparing this with the standard form, we can see that h = 0, k = 0, and a = 9/8.

Vertex: The vertex is at (h, k) = (0, 0).

Focus: The focus of the parabola is given by (h, k + 1/(4a)), so in this case, the focus is (0, 0 + 1/(4*(9/8))) = (0, 2/9).

Directrix: The directrix is a horizontal line given by y = k - 1/(4a), so in this case, the directrix is y = 0 - 1/(4*(9/8)) = -2/9.

Graph: The graph of the parabola opens upward, with the vertex at the origin (0, 0). The focus is above the vertex at (0, 2/9), and the directrix is below the vertex at y = -2/9.

a) Expected value of y (E(y)) can be calculated using the formula;

Using the given probability distribution, we can calculate E(y) as;

`E(y) = Σy × f(y)= 2×0.2 + 4×0.4 + 7×0.1 + 8×0.3= 0.4 + 1.6 + 0.7 + 2.4= 5.1`

Therefore, `E(y) = 5.1`

b) Variance (Var(y)) of a probability distribution can be calculated using the formula;

`Var(y) = E(y²) - [E(y)]²`where E(y²) is the expected value of y², and E(y) is the expected value of y.

Using the above formula, we can calculate Var(y) as;

`E(y²) = Σ(y² × f(y))= 2²×0.2 + 4²×0.4 + 7²×0.1 + 8²×0.3= 0.8 + 6.4 + 4.9 + 19.2= 31.3`

Therefore, `E(y²) = 31.3`

Substituting the values of `E(y)` and `E(y²)` into the formula for `Var(y)`, we get;

Answers

a. The probability of X = 4.  P(X = 4) = 13/45. ; b.  P(X < 1) = P(X = 0) = 1 / 9. ; c.  P(2X < 4) = 7 / 15. ; d.   P(X > -10) = 1 ,  it is a probability mass function.

The probability mass function (PMF) definition is that a function that measures the probability that a random variable X will have a given discrete probability. Thus, the following function is a probability mass function:

f(x) = 2x + 5 / 45 x = 0,1, 2, 3, 4

where x is a non-negative integer or a whole number, as shown by x = 0,1,2,3,4.

Verify that the given function meets the PMF criteria:

(a) P(X = 4) = 0.3

Here, we are required to determine the probability of X = 4.

To do so, we substitute the value of 4 for x into the PMF equation.

Therefore,f(x = 4) = 2 × 4 + 5 / 45 = 13 / 45

Thus, P(X = 4) = 13/45.

(b) P(x < 1) = 0.25

In this case, we are required to determine the probability of X < 1.

Therefore,f(x = 0) = 2 × 0 + 5 / 45 = 5 / 45

Thus, P(X < 1) = P(X = 0) = 5 / 45 = 1 / 9.

(c) P(2X < 4) = 0.45

Here, we are required to determine the probability of 2X < 4.

Therefore,f(x = 0) = 2 × 0 + 5 / 45 = 5 / 45

f(x = 1) = 2 × 1 + 5 / 45 = 7 / 45

f(x = 2) = 2 × 2 + 5 / 45 = 9 / 45

Thus, P(2X < 4) = P(X = 0) + P(X = 1) + P(X = 2) = 5 / 45 + 7 / 45 + 9 / 45 = 21 / 45 = 7 / 15.

(d) P(X > -10) = 1

Since X can only be 0, 1, 2, 3, or 4, and all are greater than -10, P(X > -10) = 1.

All the requested probabilities are exact fractions and the given function satisfies the PMF criteria.

Answers

The correct answer is option A and B.

A joint probability distribution is known to be independent if its probability distribution of one variable is not affected by another. Joint probability density functions f (x, y) that do not satisfy this condition are not SA independent. The following are the three given joint probability density functions and their corresponding analyses:

A) f(x,y) = 4x²y³

Probability density function's range is x ∈ [0,1] and y ∈ [0,1].

Calculating marginal probability density functions, we have:
fx(x) = ∫f(x,y)dy = ∫4x²y³dy = [2x²y⁴]₀¹ = 2x²

fy(y) = ∫f(x,y)dx = ∫4x²y³dx = [4/3 y³x³]₀¹ = 4/3 y³

Since  fx(x).fy(y) ≠ f(x,y), then X and Y are not SA independent.

B) f(x,y) = (x³y + xy³)

Probability density function's range is x ∈ [0,1] and y ∈ [0,1].

Calculating marginal probability density functions, we have:
fx(x) = ∫f(x,y)dy = ∫(x³y + xy³)dy = [1/2 x³y² + 1/2 xy⁴]₀¹ = 1/2 x³ + 1/2 x

f(x,y) = ∫f(x,y)dx = ∫(x³y + xy³)dx = [1/2 x⁴y + 1/2 x²y³]₀¹ = 1/2 y + 1/2 y³

Since  fx(x).fy(y) ≠ f(x,y), then X and Y are not SA independent.

C) f(x,y) = 6e^(−3x−2y)

Probability density function's range is x ∈ [0,∞) and y ∈ [0,∞).

Calculating marginal probability density functions, we have:
fx(x) = ∫f(x,y)dy = ∫6e^(−3x−2y)dy = [-3/2 e^(−3x−2y)]₀∞ = 3/2 e^(−3x)fy(y) = ∫f(x,y)dx = ∫6e^(−3x−2y)dx = [-1/3 e^(−3x−2y)]₀∞ = 1/3 e^(−2y)

Since fx(x).fy(y) ≠ f(x,y), then X and Y are not SA independent.

To find the value of k, we need to find the definite integral of the above expression with respect to x from 0 to 1.

So, let's solve this integral.

∫₁₀ 1- cos 20 sin² 20 dx

= ∫₁₀ (1- cos 20 (1- cos² 20)) dx (as sin² 20 = 1- cos² 20)

= ∫₁₀ (1- cos 20 + cos² 20) dx

= [x - sin 20 + 1/2 x (2cos² 20-1)]₁₀

= 1- sin 20 + 1/2 (2cos² 20-1) - 0 + 0 + 1/2 (2cos² 20-1)

= 3/2 cos² 20 - sin 20 + 1/2

Let this value be k.

So, k = 3/2 cos² 20 - sin 20 + 1/2

Now, let's solve the following:

sin x - cos x = sin 20 - cos 20 …(2)

From (2), we get

tan x = sin 20 - cos 20 / cos x - sin x

tan x = - tan (45 - x)
tan x = tan (-20) or tan (25)

Answers

The required equation is tt = 48 km ÷ rr kilometers/hour

To write an equation that represents how many hours (tt) the 48 km trip will take if Saul bikes at a constant rate of rr kilometers per hour, we can use the formula for time:

time = distance ÷ speed

The distance Saul has to cover is 48 km, and he bikes at a constant rate of rr kilometers per hour.

Therefore, we can substitute these values into the formula above:

tt = 48 km ÷ rr kilometers/hour

This is the required equation.

Answers

The dominant strategy for each player in this three-player game is R.

In game theory, a dominant strategy is a strategy that yields the best outcome for a player regardless of the strategies chosen by the other players. To identify the dominant strategy for each player in this game, we can consider the payoffs for each strategy combination.

Starting with Player 1, we can see that choosing strategy L results in a payoff of 2 when Player 2 plays U or D, and a payoff of 0 when Player 2 plays L. On the other hand, choosing strategy R results in a payoff of 2 when Player 2 plays U or D, and a payoff of 5 when Player 2 plays L. Since 5 > 2, Player 1's dominant strategy is R.

Similarly, for Player 2, we can see that choosing strategy L results in a payoff of 2 when Player 3 plays L or R, and a payoff of 0 when Player 3 plays U or D. On the other hand, choosing strategy R results in a payoff of 2 when Player 3 plays L or R, and a payoff of 1 when Player 3 plays U or D. Since 2 > 1, Player 2's dominant strategy is also R.

Finally, for Player 3, we can see that choosing strategy L results in a payoff of 2 when both Player 1 and Player 2 play L or R, and a payoff of 0 when either Player 1 or Player 2 plays U or D. On the other hand, choosing strategy R results in a payoff of 2 when both Player 1 and Player 2 play L or R, and a payoff of 1 when either Player 1 or Player 2 plays U or D. Since 2 > 1, Player 3's dominant strategy is also R.

Therefore, the dominant strategy for each player in this three-player game is R. It's worth noting that, unlike in other games, there is no Nash equilibrium in this game where all players are playing their dominant strategies simultaneously. Instead, any combination of R and L could be a Nash equilibrium, depending on the choices made by the other players.

Find the value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject H, for the given level of significance a Two-talled test with best statistica-2.14 and 0.06 Palue Round to four decimal places as needed) State your conclusion O Falto O Reje Hy

Answers

Answer : The calculated p-value (0.0322) is less than the significance level (α = 0.05), we reject the null hypothesis H0.

Explanation :

The problem requires to find the value for the indicated hypothesis test with the given standardized test statistic, z and decide whether to reject H, for the given level of significance a. The given information is a two-tailed test with a best statistic of -2.14 and 0.06 p-value. So, we need to determine whether to reject or fail to reject the null hypothesis H0.

Null hypothesis: H0: µ = µ0

The alternative hypothesis: H1: µ ≠ µ0

Level of significance: α = 0.05 (for two-tailed)

Since the alternative hypothesis is two-tailed, the significance level is split into two equal parts, with each tail having a significance level of 0.025 (α/2).

The rejection region for this test is given as: Reject H0 if z > zα/2 or z < -zα/2 where zα/2 is the critical value of the standard normal distribution such that P(Z > zα/2) = α/2 or P(Z < -zα/2) = α/2.

The p-value is the probability of obtaining a test statistic as extreme as the one observed, given that the null hypothesis is true. If the p-value is less than the significance level α, we reject the null hypothesis. If the p-value is greater than or equal to α, we fail to reject the null hypothesis.

Given, the best statistic, z = -2.14P-value, P(Z < -2.14) = 0.0161 (from z-table)

Since this is a two-tailed test, we need to multiply the p-value by 2, i.e., P-value = 2(0.0161) = 0.0322

Since the calculated p-value (0.0322) is less than the significance level (α = 0.05), we reject the null hypothesis H0.

Thus, we can conclude that the evidence supports the alternative hypothesis that the population mean is not equal to µ0. So, the decision is to reject H0.

Answers

Let's consider the function `f(x) = x^2-4`. Now, `y = f(x) + 4`.The inverse function of `f(x)` is `f^-1(x) = sqrt(x+4)` where `x>=-4`.Note that if we want to find the derivative of `f^-1(x)` with respect to `x`, we need to use the inverse function rule, which is given by `d/dx[f^-1(x)] = 1/f'(f^-1(x))`.Then, `f'(x) = 2x` and `f'(f^-1(x)) = 2f^-1(x)`.

Therefore, the derivative of `f^-1(x)` with respect to `x` is `d/dx[f^-1(x)] = 1/2f^-1(x)`.But we need to find the derivative of `y=f^-1(x)+4` with respect to `x`, so we use the chain rule, which gives `dy/dx = d/dx[f^-1(x)+4] = d/dx[f^-1(x)] = 1/2f^-1(x)`.So, on any interval where the inverse function `y = f^-1(x)` exists, the derivative of `y = f^-1(x) + 4` with respect to `x` is `1/2sqrt(x+4)`.Hence, the answer is "On any interval where the inverse function `y=f^-1(x)` exists, the derivative of `y=f^-1(x) + 4` with respect to `x` is `1/2sqrt(x+4)`.

Answers

a. Para determinar si la función es creciente o decreciente, podemos examinar la primera derivada de Clp) con respecto a p.

Si la primera derivada es positiva, la función es creciente; si es negativa, la función es decreciente.

Calculamos la primera derivada de Clp):

[tex]\frac{d(Clp)}{dp}= 16 -\frac{110}{p}[/tex]

Observamos que la derivada es negativa cuando p > 110/16, y positiva cuando p < 110/16.

Por lo tanto, la función Clp) es decreciente cuando p > 110/16 y creciente cuando p < 110/16.

b. Para calcular el costo de no eliminar ningún residuo, el costo sería Clp) cuando p = 0:

[tex]Cl0) = \frac{16(0)}{(110 - 0)} = 0[/tex]

Para calcular el costo de eliminar el 50% de los residuos, el costo sería Clp) cuando p = 0.5:

[tex]Cl0.5) = \frac{16(0.5)}{(110 - 0.5)}= \frac{8}{109.5}[/tex]

Para calcular el costo de eliminar todos los residuos, el costo sería Clp) cuando p = 110:

[tex]Cl110) = \frac{16(110)}{(110 - 110)} =[/tex] undefined (no está definido porque habría una división por cero)

c. En la práctica, interesa estudiar esta función para valores de p que sean realistas y significativos para el problema.

En este caso, sería relevante estudiar la función para valores de p en el intervalo [0, 110], ya que p representa la cantidad de residuos eliminados y no puede ser negativo ni superar la cantidad total de residuos generados.

d. Para dibujar la gráfica de la función Clp), podemos asignar diferentes valores a p en el intervalo [0, 110] y calcular los correspondientes valores de Clp).

Luego, trazamos los puntos resultantes y los unimos para obtener la gráfica.

e. Para determinar si la función tiene máximos o mínimos, podemos examinar la segunda derivada de Clp) con respecto a p. Si la segunda derivada es positiva, la función tiene un mínimo; si es negativa, tiene un máximo; y si la segunda derivada es cero, no se puede determinar.

Calculamos la segunda derivada de Clp):

[tex]\frac{d^2Clp)}{dp^2} =\frac{110}{p^2}[/tex]

La segunda derivada es siempre positiva, lo que significa que la función Clp) no tiene máximos ni mínimos.

f. El valor de p no puede ser negativo, ya que representa la cantidad de residuos eliminados, por lo que p ≥ 0.

g. La función Clp) no tiene asíntotas, ya que no hay valores a los que tienda indefinidamente a medida que p se acerca a infinito o menos infinito.

En este contexto, esto significa que no hay un límite en el costo a medida que la cantidad de residuos eliminados tiende a infinito o cero.

Answers

From the list of Z-scores below, the only score that corresponds to an outlier is -3.00:1.03, 0.99, 1.95, -3.00, -1.23, -2.13, -3.12, 1.32On a 60 point written exam, a student's score is normally distributed with a mean of 45 and a standard deviation of 7.

The Z score formula is used to calculate the Z score of a student's score on a 60 point exam if he/she receives a score of 50:Z = (x - μ) / σ

Z = (50 - 45) / 7

Z = 5 / 7

Z = 0.71

Therefore, a score of 50 on a 60 point exam corresponds to a Z-score of 0.71.

To compute the probability that a student will receive a score of 52 or higher, we must first calculate the Z-score of the 52 score:X = 52

Z = (x - μ) / σ

Z = (52 - 45) / 7

Z = 1

Therefore, the probability of a student receiving a score of 52 or above is the probability of a Z-score greater than or equal to 1.

Using a standard normal distribution table, we can find that the probability of a Z-score greater than or equal to 1 is 0.1587.

Therefore, the probability of a student getting 52 or above is 15.87%.

1X + 1Y < =10 B
5X + 3Y < =45 C
X, Y > =0

Answers

The given linear programming problem does not exhibit infeasibility or unboundedness, but it does have alternate optimal solutions.

To analyze the given linear programming problem, we start by examining the constraints. The first constraint, 1X + 2Y ≤ 16, defines a feasible region that lies below the line formed by this equation. The second constraint, A1X + 1Y ≤ 10, represents a feasible region below its corresponding line. Lastly, the third constraint, 5X + 3Y ≤ 45, defines a feasible region below its line.

When we combine these constraints, we find that the feasible region is the intersection of all three regions, which forms a feasible polygon. Since the objective function, 3X + 3Y, is linear, it will either have a maximum value at a vertex of the feasible polygon or along one of its boundary lines.

To determine the optimal solution, we need to evaluate the objective function at all the vertices of the feasible polygon. The alternate optimal solutions occur when multiple vertices yield the same maximum value for the objective function. If two or more vertices have the same maximum value, then the problem exhibits alternate optimal solutions.

Therefore, in this case, the linear programming problem does not exhibit infeasibility or unboundedness, but it does have alternate optimal solutions.

Equation of parabola whose vertex is (2,5) and focus (2,2) is

Answers

The equation of the parabola whose vertex is (2, 5) and focus (2, 2) is:y = (1/8)(x - 2)² + 5.

The equation of the parabola whose vertex is (2,5) and focus (2,2) is: y = (1/8)(x - 2)² + 5.

Step-by-step explanation:

Given the vertex of the parabola is (2, 5)and the focus is (2, 2).The parabola is said to be opening downwards because the focus lies below the vertex. We know that, if (a,b) is the vertex and the parabola opens downward, then the equation of the parabola can be given by: (y - b) = - (1/4a)(x - a)²

This is the required equation of the parabola. The parabola is opening downwards. The distance from the vertex to the focus is 5 - 2 = 3. Therefore the distance from the vertex to the directrix is also 3.

Hence, the equation of the directrix is y = 5 + 3 = 8. (Since the parabola opens downwards). The equation of the parabola with the given vertex and focus is: (y - 5) = - (1/12)(x - 2)²4a = - 12a = - 3

The value of 'a' is - 3 in the above equation. Let's simplify it by substituting the value of 'a' in the equation.(y - 5) = - (1/12)(x - 2)²- 36(y - 5) = (x - 2)² We get the above equation by simplifying.

find the general solution of the given differential equation. y(6) − y'' = 0

Answers

The given differential equation is y(6) - y'' = 0. To find the general solution, we need to solve the differential equation and express the solution in terms of a general form with arbitrary constants is  y(x)  = c1e^x + c2e^(-x)

The general solution of the differential equation y(6) - y'' = 0 is y(x) = c1e^x + c2e^(-x), where c1 and c2 are arbitrary constants.
Explanation: We start by assuming a solution of the form y(x) = e^(rx), where r is a constant. Taking the first and second derivatives of y(x), we have y' = re^(rx) and y'' = r^2e^(rx). Substituting these derivatives into the differential equation, we get:
e^(6r) - r^2e^(rx) = 0
Since e^(rx) is never zero, we can divide both sides by e^(rx):
1 - r^2 = 0
Solving for r, we have two possible solutions: r = 1 and r = -1. Therefore, the general solution of the differential equation is:y

   y(x)  = c1e^x + c2e^(-x),
where c1 and c2 are arbitrary constants that can be determined from initial conditions or additional information. This general solution represents the set of all possible solutions to the given differential equation.

Answers

A list can be created where the mean, median, and mode are 45 and only two values are the same. The values in the list are: 44, 45, 45, 46, and 47.

The mean is the average of the values in a list, the median is the middle value when the list is ordered, and the mode is the value that occurs most frequently in the list. In order for the mean, median, and mode to be the same, the list must be symmetric. In order for only two values to be the same, there must be two values that are the same, and the other values must be different.To create a list where the mean, median, and modes are 45 and only two values are the same, we can start by selecting a value for the median. Since the median is the middle value when the list is ordered, we can choose 45 as the median. This means that there must be an equal number of values above and below 45.
To make the list symmetric, we can choose values that are one less than and one greater than 45. This gives us the list: 44, 45, 46.

Now we need to add two more values to the list so that there are only two values that are the same. We can choose values that are one less than and one greater than the mode, which is also 45. This gives us the list: 44, 45, 45, 46, 47.
, a list can be created where the mean, median and the mode are 45 and only two values are the same. The values in the list are: 44, 45, 45, 46, and 47.
A list can be made where the mean, median, and mode are 45, and only two values are the same. To make the list symmetrical, the median value must be 45. As a result, there must be an equal number of values above and below 45. For the list to be symmetric, we need to pick values that are one less and one greater than 45. The list will be 44, 45, 46.We still need two more values to complete the list, with only two values being the same.

(7) If you deposit $100 monthly into a bank account that earns interest, how much will you have in your account after 5 years of saving? Interest rate is 6% per year compounded quarterly. 56.765 57.18

Answers

Therefore, after 5 years of saving $100 per month in a bank account that earns interest at a rate of 6% per year compounded quarterly, you will have $134.90 in your account.

To determine the total amount of money you will have in your bank account after saving for 5 years with an initial deposit of $100 per month and an interest rate of 6% per year compounded quarterly, we can use the formula for compound interest. The formula is given by:

A = P (1 + r/n)^(n*t)

where:
A = total amount after t years
P = principal amount (the initial deposit)
r = annual interest rate (in decimal)
n = number of times the interest is compounded per year
t = number of years

Using the formula above, we have:

P = $100
r = 6% per year
n = 4 (compounded quarterly)
t = 5 years

Substituting these values into the formula above, we get:

A = $100(1 + 0.06/4)^(4*5)
A = $100(1 + 0.015)^20
