Given that f(x) = x² - 2x + 5. We need to find the absolute maximum and minimum of the function.Let us differentiate the function to find critical points, that is, f '(x) = 2x - 2.We know that f(x) is maximum or minimum at critical points. So, f '(x) = 0 or f '(x) does not exist.

Let's solve for x.2x - 2 = 0⇒ 2x = 2⇒ x = 1Therefore, f '(1) = 2(1) - 2 = 0The critical point is x = 1.Now, we need to test if this critical point gives an absolute maximum or minimum.To do this, we can check the value of f(x) at this point as well as the values of f(x) at the endpoints of the domain of x. Here, the domain is -∞ < x < ∞.Let's begin by calculating f(x) at the critical point.x = 1⇒ f(1) = (1)² - 2(1) + 5= 4Therefore, the function has a maximum at x = 1.

Now, let's check the values of f(x) at the endpoints of the domain.x → -∞⇒ f(x) → ∞x → ∞⇒ f(x) → ∞Therefore, there are no minimum values of the function.To summarize, the absolute maximum of the function f(x) = x² - 2x + 5 is 4 and there is no absolute minimum value of the function as f(x) approaches infinity for both positive and negative values of x.

Answer:

27

Step-by-step explanation:

To evaluate an expression we need to find the numerical value of the expression by substituting appropriate values for the variables and performing the indicated mathematical operations.

Given rational expression:

[tex]\dfrac{6x^2}{y^3}[/tex]

To evaluate the given expression when x = 6 and y = 2, substitute x = 6 and y = 2 into the expression and solve.

[tex]\dfrac{6(6)^2}{(2)^3}[/tex]

Following the order of operations, begin by evaluating the exponents first.

To square a number, we multiply it by itself.

[tex]\implies 6^2 = 6 \times 6 = 36[/tex]

To cube a number, we multiply it by itself twice.

[tex]\implies 2^3 = 2 \times 2 \times 2 = 8[/tex]

Therefore:

[tex]\dfrac{6(6)^2}{(2)^3}=\dfrac{6 \cdot 36}{8}[/tex]

Multiply the numbers in the numerator:

[tex]\dfrac{216}{8}[/tex]

Finally, divide 218 by 8:

[tex]\dfrac{216}{8}=27[/tex]

Therefore, the evaluation of the given expression when x = 6 and y = 2 is 27.

[tex]\hrulefill[/tex]

As one calculation:

[tex]\begin{aligned}x=6, y=2 \implies \dfrac{6x^2}{y^3}&=\dfrac{6(6)^2}{(2)^3}\\\\&=\dfrac{6 \cdot 36}{8}\\\\&=\dfrac{216}{8}\\\\&=27\end{aligned}[/tex]

The correlation coefficient must necessarily be equal to -0.9.

The coefficient of determination (R²) is a statistical measure that indicates how well the regression line predicts the data points. It is a proportion of the variance in the dependent variable (y) that can be predicted by the independent variable (x).The value of R² ranges from 0 to 1, with 1 indicating a perfect fit between the regression line and the data points. The closer R² is to 1, the more accurate the regression line is in predicting the data points.

The formula to calculate the correlation coefficient (r) is as follows:r = (n∑xy - ∑x∑y) / √((n∑x² - (∑x)²) (n∑y² - (∑y)²))where x and y are the two variables, n is the number of data points, and ∑ represents the sum of the values.To find the correlation coefficient (r) from the coefficient of determination (R²), we take the square root of R² and assign a positive or negative sign based on the direction of the linear relationship (positive or negative).

The formula to find the correlation coefficient (r) from the coefficient of determination (R²) is as follows:

r = ±√R²For example, if R² is 0.81, then r = ±√0.81 = ±0.9

Since the linear regression equation is y = 15- 0.49

x1, this means that the slope of the line is -0.49.

This indicates that there is a negative linear relationship between the two variables, meaning that as x1 increases, y decreases.

Since the correlation coefficient (r) must have a negative sign, we have :r = -0.9

The probabilities have been computed to be as follows: i) P (S2 = 2, S5 = 1) = 0.0441, ii) P (S2 = 2, S4 = 3, S5 = 1) = 0.0189.

The probabilities can be computed using the formula:

P (Sn = i, Sm = j) = P (Sn = i, Sn - m = j - i) = P (Sn = i)*P (Sn - m = j - i),

where i, j ∈ Z, n > m ≥ 0.

Then,

P (Sn = i) = (p/q) ^ (n+i)/2√πn, and

P (Sn - m = j - i) = (p/q) ^ ((n-m+ (j-i))/2) √ ((n+m- (j-i))/π(n-m))

For, P (S2 = 2, S5 = 1), i.e., i = 2, j = 1, n = 5, m = 2.

Then,

P (S2 = 2, S5 = 1) = P (S2 = 2) * P (S3 = -1) * P (S4 = -2) * P (S5 - 2 = -1) = (0.3) * (0.7) * (0.7) * (0.3) = 0.0441

For, P (S2 = 2, S4 = 3, S5 = 1), i.e., i = 2, j = 1, n = 5, m = 4.

Then,

P (S2 = 2, S4 = 3, S5 = 1) = P (S2 = 2) * P (S2 = 3 - 4) * P (S5 - 4 = 1 - 2) = (0.3) * (0.7) * (0.3) = 0.0189

Thus, we have computed the required probabilities as follows:

The normal distribution is approximately 65.328 minutes.

To find the value that separates the top 15% of the data from the bottom 85% in a normal distribution with a mean of 56 minutes and a standard deviation of 9 minutes, we can use the Z-score.

The Z-score represents the number of standard deviations a data point is from the mean. In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

To find the Z-score corresponding to the top 15% of the data, we need to find the Z-score that corresponds to the area of 0.15 in the tail of the distribution (above the mean).

Using a Z-table or a statistical calculator, we can find that the Z-score corresponding to the top 15% (above the mean) is approximately 1.0364.

To find the value that corresponds to this Z-score, we can use the formula:

Value = Mean + (Z-score * Standard Deviation)

Plugging in the values:

Mean = 56 minutes

Standard Deviation = 9 minutes

Z-score = 1.0364

Value = 56 + (1.0364 * 9)

Value = 56 + 9.328

Value ≈ 65.328

Therefore, the value (score) that separates the top 15% of the data from the bottom 85% for the given normal distribution is approximately 65.328 minutes.

In other words, a + b = b + a. Vector addition is also associative, which means that the way the vectors are grouped for addition does not affect the result. In other words, (a + b) + c = a + (b + c).

To find the sum of the given vectors a = 2, 0, 1 and b = 0, 8, 0, we can simply add the corresponding components of the vectors as shown below: a + b = (2 + 0), (0 + 8), (1 + 0)= 2, 8, 1

Therefore, the sum of the given vectors a and b is 2, 8, 1.

The sum of two or more vectors is obtained by adding the corresponding components of the vectors. This operation is called vector addition and it is one of the basic operations of vector algebra. Vector addition is one of the fundamental operations in vector algebra.

In vector algebra, a vector is represented as an ordered set of numbers that describe its magnitude and direction. The magnitude of a vector is the length of the line segment representing the vector while the direction of a vector is the direction of the line segment that represents the vector.

When two or more vectors are added, their corresponding components are added to give the sum of the vectors. The sum of the vectors is a vector that represents the combined effect of the individual vectors. For example, if we have two vectors a and b, then the sum of the vectors is obtained by adding the corresponding components of the vectors.

If a = (a1, a2, a3) and b = (b1, b2, b3), then a + b = (a1 + b1, a2 + b2, a3 + b3). This is the basic rule for vector addition and it is easy to understand and apply. Vector addition is commutative, which means that the order of addition does not affect the result.

The probability that more than 20 customers will arrive at the drive-thru is 0.025.

Poisson distribution is used to find the probability of a certain number of events occurring in a specified time interval. It is used when the event is rare, and the sample size is large. In Poisson distribution, we have an average arrival rate (λ) and the number of arrivals (x).

The probability of x events occurring during a given time period is :

P(x;λ) = λx e−λ/x!, where e is the Euler's number (e = 2.71828182846) and x! is the factorial of x.

To find the probability that more than 20 customers will arrive at the drive-thru during a given hour, we use the Poisson distribution as follows:

P(x > 20) = 1 - P(x ≤ 20)

P(x ≤ 20) = ∑ (λ^x * e^-λ)/x!, x = 0 to 20

Let's find the probability P(x ≤ 20).

P(x ≤ 20) = ∑ (λ^x * e^-λ)/x!; x = 0 to 20

P(x ≤ 20) = ∑ (17^x * e^-17)/x!; x = 0 to 20

P(x ≤ 20) = 0.975

Therefore, P(x > 20) = 1 - P(x ≤ 20)

P(x > 20) = 1 - 0.975

P(x > 20) = 0.025

Approximately 30.79% of trucks can be expected to travel less than 15,000 or more than 40,000 miles per year.

To determine the percentage of trucks that can be expected to travel either less than 15 or more than 40 thousand miles in a year, we can use the properties of the normal distribution.

Let's calculate the z-scores for 15,000 miles and 40,000 miles using the given mean and standard deviation:

For 15,000 miles:

z-score = (x - mean) / standard deviation

= (15,000 - 30,000) / 12,000

= -15,000 / 12,000

= -1.25

For 40,000 miles:

z-score = (x - mean) / standard deviation

= (40,000 - 30,000) / 12,000

= 10,000 / 12,000

= 0.8333

Now, we can use a z-table or a statistical calculator to find the percentage of trucks that fall below -1.25 or above 0.8333 in terms of z-scores.

From the z-table or calculator, we find the following probabilities:

For a z-score of -1.25, the corresponding probability is approximately 0.1056 or 10.56%.

For a z-score of 0.8333, the corresponding probability is approximately 0.7977 or 79.77%.

To find the percentage of trucks that travel either less than 15,000 or more than 40,000 miles in a year, we add the probabilities together:

10.56% + (100% - 79.77%) = 10.56% + 20.23% = 30.79%

Therefore, approximately 30.79% of trucks can be expected to travel either less than 15,000 or more than 40,000 miles in a year.

To compute the circulation of the vector field F around the curve C, we need to evaluate the line integral ∮C F · dr, where dr is the differential vector along the curve C. Let's calculate the circulation for each segment of the curve:

(a) Line segment from (0, 0, 0) to (1, 0, 0):

The differential vector dr along this segment is dr = dx i, where i is the unit vector in the x-direction, and dx represents the differential length along the x-axis. Since the vector field F = <y, 0, 0>, we have F · dr = (y)dx = 0, because y = 0 along this line segment. Hence, the circulation along this segment is zero.

(b) Line segment from (1, 0, 0) to (1, 1, 0):

The differential vector dr along this segment is dr = dy j, where j is the unit vector in the y-direction, and dy represents the differential length along the y-axis. Since the vector field F = <y, 0, 0>, we have F · dr = (y)dy = y dy. Integrating y dy from 0 to 1 gives us the circulation along this segment. Evaluating the integral, we get:

∫[0,1] y dy = [y^2/2] from 0 to 1 = (1^2/2) - (0^2/2) = 1/2.

(c) Line segment from (1, 1, 0) to (0, 1, 0):

The differential vector dr along this segment is dr = -dx i, where i is the unit vector in the negative x-direction, and dx represents the differential length along the negative x-axis. Since the vector field F = <y, 0, 0>, we have F · dr = (y)(-dx) = -y dx. Integrating -y dx from 1 to 0 gives us the circulation along this segment. Evaluating the integral, we get:

∫[1,0] -y dx = [-y^2/2] from 1 to 0 = (0^2/2) - (1^2/2) = -1/2.

(d) Line segment from (0, 1, 0) to (0, 0, 0):

The differential vector dr along this segment is dr = -dy j, where j is the unit vector in the negative y-direction, and dy represents the differential length along the negative y-axis. Since the vector field F = <y, 0, 0>, we have F · dr = (y)(-dy) = -y dy. Integrating -y dy from 1 to 0 gives us the circulation along this segment. Evaluating the integral, we get:

∫[1,0] -y dy = [-y^2/2] from 1 to 0 = (0^2/2) - (1^2/2) = -1/2.

To compute the total circulation around the curve C, we sum up the circulations along each segment:

Total Circulation = Circulation(a) + Circulation(b) + Circulation(c) + Circulation(d)

= 0 + 1/2 + (-1/2) + (-1/2)

= 0.

Therefore, the total circulation of the vector field F around the curve C, which is a unit square in the xy-plane, is zero.

We have Y(t) = X²(t) ⇒ X(t) = ±(Y(t))^(1/2).

Using g(x) = x², we have g^(-1)(y) = ±y^(1/2).

Differentiating g^(-1)(y) with respect to y, we have d/dy(g^(-1)(y)) = ±1/(2√y).

We consider X(t) = (Y(t))^(1/2). Therefore, the pdf of Y(t) is given by:

fY(t) = fX(t)|dX(t)/dY(t)|.

Since X(t) is a Wiener process, its pdf fX(t) is given by the normal distribution function N(0, t) with mean 0 and variance t. Therefore, we have:

fY(t) = 1/(√(2πt)) |1/(2√Y(t))| e^(-(1/2t)(Y(t))).

Simplifying the above expression, we get:

fY(t) = 1/(2√(πt)Y(t)) e^(-(1/2t)(Y(t))).

Hence, the pdf of Y(t) is given by fY(t) = 1/(2√(πt)Y(t)) e^(-(1/2t)(Y(t))).

(b) The conditional pdf of Y(t₂) and Y(t₁) is given by:

fY(t₂|t₁) = f(t₁,t₂)/fY(t₁),

where f(t₁,t₂) is the joint pdf of Y(t₁) and Y(t₂), which is given by:

f(t₁,t₂) = fX(x₁) fX(x₂),

where x₁ and x₂ are the values taken by X(t₁) and X(t₂) respectively.

Substituting fX(x) = 1/(√(2πt)) e^(-(x²/2t)) and X(t₁) = x₁ and X(t₂) = x₂, we have:

f(t₁,t₂) = 1/(2πt₁t₂) e^(-(x₁²/2t₁ + x₂²/2t₂)).

Now, substituting Y(t₁) = X²(t₁) = x₁² and Y(t₂) = X²(t₂) = x₂² in f(t₁,t₂), we have:

f(t₁,t₂) = 1/(2πt₁t₂) e^(-(y(t₁)/2t₁ + y(t₂)/2t₂)).

Therefore, the conditional pdf of Y(t₂) given Y(t₁) is given by:

fY(t₂|t₁) = f(t₁,t₂)/fY(t₁).

Substituting the values of f(t₁,t₂) and fY(t₁) from above, we have:

fY(t₂|t₁) = (1/√(2π(t₂-t₁))) y(t₂)/y(t₁) e^(-(y(t₂)+y(t₁))/(2(t₂-t₁)).

Hence, the conditional pdf of Y(t₂) given Y(t₁) is given by fY(t₂|t₁) = (1/√(2π(t₂-t₁))) y(t₂)/y(t₁) e^(-(y(t₂)+y(t₁))/(2(t₂-t₁))).

1 solution of a triangle exists because all of the angles are less than 180 degrees and the sides and angles have non-negative values.

Therefore, there exists only one triangle.

The given values are:

a = √2, b = √7, and p = 105

The sine law is applied to determine the angle opposite to a. We know that sin(A)/a = sin(B)/b = sin(C)/c

where A, B, and C are the angles of a triangle, and a, b, and c are the opposite sides to A, B, and C, respectively.

Therefore, sin(A)/√2 = sin(B)/√7

We can now get sin(A) and sin(B) by cross-multiplication:

√7 * sin(A) = √2 * sin(B)sin(A) / sin(B) = √(2/7)

Using the sine law, we can now calculate the angle C:

sin(C)/p = sin(B)/b

Therefore, sin(C) = (105 sin(B))/√7

Using the equation sin²(B) + cos²(B) = 1, we can determine

cos(B) and cos(A)cos(B)

= √(1 - sin²(B)) = √(1 - 2/7)

= √(5/7)cos(A) = (b cos(C))/a

= (√7 cos(C))/√2Since sin(A)/√2

= sin(B)/√7sin(A)

= (√2/√7)sin(B)sin(A)

= (√2/√7) [√(1 - cos²(B))]

We can solve the equations above using substitution to find sin(B) and sin(A).

Answer:

Step-by-step explanation:

Assuming the -1 is not a typo, we can see that the function h is a linear function. Thus we can simply plug in -1 and 1 for h, then take the average of the 2 values we get.

h(-1) = 26, and h(1) = 8.

Average = (26 + 8)/ 2 = 17

The problem asks to find the average value of h on the interval [-1,1]. To do this, use the formula avg = 1/(b-a)∫[a,b] h(x)dx, where a and b are the endpoints of the interval. The integral can be evaluated from -1 to 1, resulting in an average value of approximately 0.0611.

The problem is asking us to find the average value of the function h on the given interval. The function is h(u) = (18 − 9u)−1 and the interval is [−1, 1].

To find the average value of the function h on the given interval, we can use the following formula: avg = 1/(b-a)∫[a,b] h(x)dx where a and b are the endpoints of the interval. In this case, a = -1 and b = 1, so we have:

avg =[tex]1/(1-(-1)) ∫[-1,1] (18 - 9u)^-1 du[/tex]

Now we need to evaluate the integral. We can use u-substitution with u = 18 - 9u and du = -1/9 du:∫(18 - 9u)^-1 du= -1/9 ln|18 - 9u|We evaluate this from -1 to 1:

avg = [tex]1/2 ∫[-1,1] (18 - 9u)^-1 du[/tex]

= [tex]1/2 (-1/9 ln|18 - 9u|)|-1^1[/tex]

= 1/2 ((-1/9 ln|9|) - (-1/9 ln|27|))

= 1/2 ((-1/9 ln(9)) - (-1/9 ln(27)))

= 1/2 ((-1/9 * 2.1972) - (-1/9 * 3.2958))

= 1/2 ((-0.2441) - (-0.3662))

= 1/2 (0.1221)

= 0.0611

Therefore, the average value of the function h on the interval [-1,1] is approximately 0.0611.

hyp² = opp² + adj²

x² = 8² +5³

x² = 64 + 25

x² = 89

x= √89

x= 9.43

To the nearest degree, the value of x is 2 degrees.

So, the correct option is (B) 67.

Given equation is: √√58 = x

To find the value of x, we will proceed as follows:

We can also write the equation as follows:

x = (58)^(1/4)^(1/2)

x = (2*29)^(1/4)^(1/2)

x = (2)^(1/2) * (29)^(1/4)^(1/2)

x = √2 * √√29

So, we need to calculate the value of x in degrees.

Since, √2 = 1.4142 (approximately) and √√29 = 1.5555 (approximately)

So, the value of x is:

x = 1.4142 * 1.5555

The standard deviation of a sample distribution, according to the central limit theorem, is equal to the population standard deviation divided by the square root of the sample size.

The central limit theorem states that when independent random variables are added, their sum tends toward a normal distribution, regardless of the shape of the original variables' distribution. This holds true under certain conditions, such as a sufficiently large sample size.

To calculate the standard deviation of a sample distribution, we divide the population standard deviation by the square root of the sample size. This adjustment accounts for the fact that as the sample size increases, the variability of the sample means decreases.

In summary, the standard deviation of a sample distribution is obtained by dividing the population standard deviation by the square root of the sample size. This relationship is based on the central limit theorem, which allows us to make inferences about a population based on a sample.
