Step-by-step explanation:

Answer: y = x + 1

Step-by-step explanation:

The best estimate for the number of mistakes that would occur if a student typed 15 words per minute is 8.5.

An appropriate data display for this data could be a line graph. The x-axis represents the typing speed (words per minute) and the y-axis represents the number of mistakes. Each speed value has a corresponding point on the graph which represents the average number of mistakes made at that speed.

To draw the graph, we can plot each point on the graph and connect them with a line. The resulting line graph would look like the following:

  |    .

14 |            .

  |         .

12 |       .

  |      .

10 |     .

  |    .

8 |   .

  |  .

6 |  .                .

  |_________________________

      10  20  30  40  50

            Speed (words per minute)

To estimate the number of mistakes for a typing speed of 15 words per minute, we can use the line graph and draw a vertical line at 15 on the x-axis. Then, we can read the corresponding value on the y-axis, which gives an estimated number of mistakes of around 8.5.

So, the best estimate for the number of mistakes that would occur if a student typed 15 words per minute is 8.5.

The point estimate for p is approximately 0.383, or 38.3% of the surveyed college students own their car.

In statistics, a point estimate is a single value that is used to estimate an unknown population parameter. A point estimate is a specific value. The point estimate is usually calculated as a sample statistic.

The point estimate for p, the population proportion of students who own their cars, can be calculated by dividing the number of students who said they own their car by the total number of students surveyed:

point estimate = number of students who own their car / total number of students surveyed

point estimate = 180 / 470

the point estimate ≈ 0.383 (rounded to three decimal places)

Therefore, the point estimate for p is approximately 0.383, or 38.3% of the surveyed college students own their cars.

The probability that wage has no effect can be determined by conducting a hypothesis test on the slope of the regression line. The null hypothesis is that the slope of the regression line is equal to zero, meaning that wage has no effect on the outcome. The alternative hypothesis is that the slope is not equal to zero, meaning that wage does have an effect on the outcome.

To find the probability that wage has no effect, we need to find the p-value for the null hypothesis. The p-value is the probability of observing a test statistic as extreme or more extreme than the one we observed, assuming that the null hypothesis is true.

If the p-value is less than the significance level (usually 0.05), we reject the null hypothesis and conclude that wage does have an effect on the outcome. If the p-value is greater than the significance level, we fail to reject the null hypothesis and conclude that there is not enough evidence to say that wage has an effect on the outcome.

So, to find the probability that wage has no effect, we need to find the p-value for the null hypothesis and round it to the third decimal place. For example, if the p-value is 0.0495, the probability that wage has no effect is 0.050.

The probability that wage has no effect is the p-value for wage in the regression model, written as a decimal and rounded to the third place.

The probability that wage has no effect on a regression model is indicated by the p-value of the coefficient for wage in the model. If the p-value is greater than 0.05, it indicates that there is a greater than 5% chance that the observed relationship between wage and the dependent variable is due to chance, and therefore wage has no effect.

To find the p-value for wage, you can look at the output of the regression model, which typically includes the coefficients, standard errors, and p-values for each independent variable in the model. The p-value for wage will be listed in the same row as the coefficient for wage.

Once you have found the p-value for wage, you can write it as a decimal and round to the third place. For example, if the p-value for wage is 0.05234, the answer would be 0.052.

Answer:

x = - 5 ± [tex]\sqrt{2}[/tex]

Step-by-step explanation:

2(x + 5)² - 3 = 1 ( add 3 to both sides )

2(x + 5)² = 4 ( divide both sides by 2 )

(x + 5)² = 2 ( take square root of both sides )

x + 5 = ± [tex]\sqrt{2}[/tex] ( subtract 5 from both sides )

x = - 5 ± [tex]\sqrt{2}[/tex]

Then

x = - 5 - [tex]\sqrt{2}[/tex] , x = - 5 + [tex]\sqrt{2}[/tex]

[tex]2(x+5)^{2} = 1 + 3 \iff 2(x+5)^{2} = 4 \iff (x+5)^{2} = 2[/tex]

[tex]|x+5| = \pm \sqrt{2}[/tex]

[tex]x + 5 = - \sqrt{2} \iff x_{1} = - \sqrt{2} - 5[/tex]

The probability that a student buys their lunch at school, given they are a junior, is 8/25.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Let J be the event that a student is a junior, and L be the event that a student buys lunch at school.

We are given -

P(J) = 5/16

P(L) = 2/3

P(L|J) = 1/4

We want to find P(L|J), the probability that a student buys lunch at school, given they are a junior.

Using Bayes' theorem, we have -

P(L|J) = P(J|L) × P(L) / P(J)

We can find P(J|L) using the formula for conditional probability -

P(J|L) = P(J and L) / P(L)

To find P(J and L), we can use the formula -

P(J and L) = P(L|J) × P(J)

Substituting in the given values, we get -

P(J and L) = (1/4) × (5/16) = 5/64

To find P(L), we are given -

P(L) = 2/3

To find P(J), we are given -

P(J) = 5/16

Now, we can find P(J|L) -

P(J|L) = P(J and L) / P(L) = (5/64) / (2/3) = 15/128

Finally, we can use Bayes' theorem to find P(L|J) -

P(L|J) = P(J|L) × P(L) / P(J) = (15/128) × (2/3) / (5/16) = 8/25

Therefore, the probability value is 8/25.

Slope of segment WU = 4/5

Slope of segment UV = -2/3

Slope of segment VW = 0

To find the slopes of each line segment of a triangle, you will need to know the coordinates of the vertices (corners) of the triangle.

We have a triangle with vertices U(x1, y1), V(x2, y2), and W(x3, y3). Then we can find the slopes of the line segments as follows:

Slope of segment UV:

The slope of the line passing through points U and V can be found using the formula:

mUV = (y2 - y1) / (x2 - x1)

From the graph: x1 = 1, y1 = 3; x2 = 4, y2 = -1

mUV = (-1 - 1) / (4 - 1) = -2/3

Slope of segment VW:

The slope of the line passing through points V and W can be found using the formula:

mVW = (y3 - y2) / (x3 - x2)

x2 = 4, y2 = -1; x3 = -4, y3 = -1

mVW = (-1 - (-1)) / (-4 -4) = 0/(-8) = 0

Slope of segment WU:

The slope of the line passing through points W and U can be found using the formula:

mWU = (y3 - y1) / (x3 - x1)

Using trigonometric functions, AO=2.14h, BO=1.54h and h = 40.9 m.

What are trigonometric functions?

Trigonometric functions are mathematical functions that relate the angles of a right triangle to the lengths of its sides. There are 6 trigonometric functions and those are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).

The sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

Now,

a) Using trigonometry, we can find that:

tan(25°) = h / AO

Therefore:

AO = h / tan(25°)=2.14h

b) Similarly, we have:

tan(33°) = h / BO

Therefore:

BO = h / tan(33°)=1.54h

c) We can use the fact that AO + BO = AB = 60 m. Substituting the expressions we found for AO and BO, we get:

h / tan(25°) + h / tan(33°) = 60

Multiplying both sides by tan(25°)tan(33°), we get:

h(tan(33°) + tan(25°)) = 60tan(25°)tan(33°)

Therefore:

h = 60tan(25°)tan(33°) / (tan(33°) + tan(25°))

h ≈ 40.9 m

hence,

          AO=2.14h, BO=1.54h and h=40.9m.

Answer:

To solve this problem, we need to know the value of x, the price per meter of cloth. Let's assume that x is given in naira. Then, the cost of 5 meters of cloth is:

5m * x naira/m = 5x naira

To find the change from 7000 naira after buying the cloth, we need to subtract the cost of the cloth from 7000 naira:

Change = 7000 naira - 5x naira

We can't find a specific answer without knowing the value of x. But, if we assume that x = 1000 naira/m, then the cost of 5 meters of cloth would be:

5m * 1000 naira/m = 5000 naira

Then, the change from 7000 naira would be:

Change = 7000 naira - 5000 naira = 2000 naira

Therefore, if the price per meter of cloth is 1000 naira, then the change from 7000 naira would be 2000 naira. However, if the actual value of x is different, then the answer would be different as well.

Answer:

Therefore, the exponential form of the equation log(c) = d is base^d = c. Note that the base could be any positive number except 1, since log base 1 is undefined.

Step-by-step explanation:

The logarithmic form log(c) = d means that d is the logarithm of c to some base, which is not specified in the given equation. To express this equation in exponential form, we can raise the base of the logarithm to the power of both sides of the equation. This gives:

base^d = c

Where "base" represents the base of the logarithm.

Therefore, the exponential form of the equation log(c) = d is base^d = c. Note that the base could be any positive number except 1, since log base 1 is undefined.

Answer:

x = - [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

the x- intercept is the value of x where the line crosses the x- axis

on the x- axis the y- coordinate of any point is zero

let y = 0 in the equation and solve for x

y = 6x + 1 , then

0 = 6x + 1 ( subtract 1 from both sides )

- 1 = 6x ( divide both sides by 6 )

- [tex]\frac{1}{6}[/tex] = x ← is the x- intercept

Answer:

 [tex]x = \frac{1}{6}y-\frac{1}{6}[/tex]

Step-by-step explanation:

Find the x-intercept of the line with equation y=6x +1

y = 6x + 1, solve for x

y = 6x + 1 subtract 6x from both sides:

y - 6x = 6x + 1 - 6x

y - 6x =  1

subtract y from both sides:

y - 6x - y =  1 - y

- 6x =  1 - y

divide both sides by -6:

- 6x/-6 =  (1 - y)/-6

x = -1/6 + 1/6 y

rearrange left side:

[tex]x = \frac{1}{6}y-\frac{1}{6}[/tex]

Again, in ∆WOX , by Pythagoras theorem , we have;

[tex]\implies WX^2 = WO^2 + OX^2 \\[/tex]

And here ,

So on substituting the respective values, we have;

[tex]\implies WX^2 = 8^2 + 6^2 \\[/tex]

From the given scenario 1, 3, 4, 5, 7, 9, 10 is combination and rest others are permutations

Permutations are the arrangements of objects in a specific order. They are a way of counting the number of ways to choose and arrange a set of objects. The order of the objects matters in permutations. For example, the number of ways to arrange the letters A, B, and C in a row is 3! (or 6), because there are 3 choices for the first letter, 2 choices for the second letter, and 1 choice for the last letter.

Combinations, on the other hand, are the ways of choosing a set of objects without regard to order. The order of the objects does not matter in combinations. For example, the number of ways to choose two letters from A, B, and C is 3C2 (or 3), because there are three possible combinations (AB, AC, BC), but they are the same set of two letters.

A. If yοu bοught the 100 shares οf Health Care Right, yοu wοuld receive $134 in annual dividends.

Annual yield is the return οn an investment οver a οne-year periοd, expressed as a percentage. It is calculated by dividing the incοme οr prοfit generated by the investment οver the cοurse οf a year by the tοtal amοunt οf mοney invested.

B. Tο calculate the annual yield, we divide the annual dividends by the tοtal cοst οf the investment:

Annual yield = annual dividends / tοtal cοst οf investment

Tοtal cοst οf investment = $28.06 per share x 100 shares = $2,806

Annual yield = $134 / $2,806 = 0.0477, οr 4.77%

Therefοre, the annual yield fοr this investment wοuld be 4.77%.

C. If yοu bοught 80 shares οf Health Care Prοvider at $40.90 per share, yοu wοuld receive a tοtal οf:

$2.24 dividend per share x 80 shares = $179.20 in annual dividends

D. Tο calculate the annual yield, we divide the annual dividends by the tοtal cοst οf the investment:

Tοtal cοst οf investment = $40.90 per share x 80 shares = $3,272

Annual yield = $179.20 / $3,272 = 0.0548, οr 5.48%

Therefοre, the annual yield fοr this investment wοuld be 5.48%.

Hence,

A. If yοu bοught the 100 shares οf Health Care Right, yοu wοuld receive $134 in annual dividends.
