The polygon does not belong to the group as it is created by a finite number of line segments and the concept of the radius of curvature is not applicable.

In this problem we have three shapes related to circle-like and ellipse-like arcs (circle, semicircle, ellipse) and a regular polygon.

Circles are closed figures created by a arc whose radius of curvature is the same at every point and ellipses are closed figures created  by a arc whose radius of curvature varies in the following interval: a ≤ r ≤ b, where a, b are the lengths of the semiaxes.

Polygons are closed figures created by a finite number of line segments and therefore the concept of radius of curvature is not applicable.

The loss on selling 50 shares of stock would be 87.50.

To calculate the loss on selling 50 shares of stock originally bought at

\(13\frac{3}{4}\) and sold at 12, we need to determine the difference between the purchase price and the selling price, and then multiply it by the number of shares sold.

First, let's convert the purchase price from a mixed fraction to a decimal. \(13\frac{3}{4}\) can be expressed as 13.75.

Next, we calculate the difference between the purchase price and the selling price:

\(13.75 - 12 = 1.75.\)

Finally, we multiply the difference by the number of shares sold:

\(1.75 \times50 = 87.50.\)

Therefore, the loss on selling 50 shares of stock would be 87.50.

The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.

For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.

Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:

| Value (x) | P(X=x) |

|---|---|

| 0 | 0.2 |

| 3 | 0.2 |

| 4 | 0.3 |

| 5 | 0.2 |

| 6 | 0.1 |

The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

The true statement is "the line that can be drawn through points D and E is contained in plane Y".

option B is the correct answer

The points x and y and points C,D,E and f are shown in the figure, the true statement is determined as follows;

We know that, if two points lie in a plane, then the line drawn through the points will contained in the same plane.

The points C lies outside the plane Y and the point D lies on the plane Y, so the line drawn through the points C and D will not contained in plane Y.

So, option (A) is NOT correct.

The points D and E, both lie in the plane Y, so the line drawn through the points D and E will also contained in plane Y.

So, option (B) is CORRECT.

Since the plane X contain infinitely many points, so F is not the only point that can lie in plane X.

So, option (C) is NOT correct.

Similarly, there are infinitely many points in the plane Y, so the points D and E are not the only points that can lie in plane Y.

So, option (D) is NOT correct.

The perimeter of Sam's string is 178 inches.

Given information:

Sam has a rectangular shaped window.

Length = 65 inches.

Width = 24 inches.

To find the perimeter:

you can use the formula:

Perimeter = 2 x (Length + Width)

Substituting the values into the formula, we have:

Perimeter = 2 x (65 + 24)

Perimeter = 2 x 89

Perimeter = 178 inches

Therefore, the perimeter of the rectangular window is 178 inches.

So, the perimeter of the rectangular window is 178 inches. This means that if you were to walk along the outline of the window, you would cover a total distance of 178 inches. It's important to note that the perimeter represents the total length of all the sides combined, and it is measured in the same unit (in this case, inches) as the length and width of the window.

The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).

First, let's find the slope of the line using the formula:

slope (m) = (change in y) / (change in x)

m = (0 - 4) / (5 - 3)

m = -4 / 2

m = -2

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Using the point (3, 4) as our reference point, we have:

y - 4 = -2(x - 3)

Expanding the equation:

y - 4 = -2x + 6

Simplifying:

y = -2x + 10

Now, let's check the given options to find the linear function with the same y-intercept:

Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)

The y-intercept is the same as the given line (10). So, this option is correct.

Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)

The y-intercept is not the same as the given line. So, this option is not correct.

Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

One reason to compute a correlation coefficient to measure the strength of the relationship between two variables is that quantify the strength and direction of the correlation in a precise and standardized way..

When we have two variables that are related, we say that there is a correlation between them. The most common way to visually represent a correlation is by plotting the data on a scatter plot, where each point represents a pair of values for the two variables.

While a scatter plot is a useful tool to visualize the relationship between two variables, it doesn't tell us how strong or weak the correlation is. For instance, two variables might show a positive correlation, but the scatter plot might be quite dispersed, indicating that there is a lot of variability in the data. In this case, we would say that the correlation is weak. On the other hand, if the scatter plot is tightly clustered around the line, we would say that the correlation is strong.

This is where the correlation coefficient comes in. The correlation coefficient is a mathematical measure that quantifies the strength and direction of the relationship between two variables. It ranges from -1 to 1, where a value of -1 indicates a perfect negative correlation, a value of 0 indicates no correlation, and a value of 1 indicates a perfect positive correlation.

To compute the correlation coefficient, we first need to calculate the covariance between the two variables. Covariance is a measure of how much the two variables vary together, and it is defined as the sum of the products of the deviations of the values from their respective means. Once we have the covariance, we can divide it by the product of the standard deviations of the two variables to get the correlation coefficient.

(b) The mean of the sampling distribution is 0.23.

(c) The standard deviation of the sampling distribution is 0.1288.

(d) The probability that the difference in sample proportions (senior - junior) of students with parking passes is greater than 30% is -0.56.

In the given question, at Westville High School there are 315 seniors and 389 juniors.

65% of the seniors have parking passes and 42% of the juniors have parking passes.

The statistics teacher selects a SRS of 30 seniors and a separate SRS of 30 juniors.

Let be the difference in the sample proportions of seniors and juniors that have parking passes.

(a) We have to find the shape of the sampling distribution.

n1*p1 = 0.65*30 = 19.5 > 10

n1*(1 - p1) = (1 - 0.65)*30 = 10.5 > 10

n2*p2 = 0.42*30 = 12.6 > 10

n2*(1 - p2) = (1 - 0.42)*30 = 17.4 > 10

Since all values are greater than 10, the sampling distribution is normally distributed.

(b) We have to find the mean of the sampling distribution.

Mean = p1 - p2

Mean = 0.65 - 0.42

Mean = 0.23

(c) We have to calculate and interpret the standard deviation of the sampling distribution.

Pooled proportion, P' = (x1 + x2)/(n1 + n2)

P' = (0.65*30 + 0.42*30)/(30 + 30)

P' = 0.535

Standard deviation = √P'(1-P')*(1/n1 + 1/n2)

Standard deviation = √0.535(1- 0.535)*(1/30 + 1/30)

Standard deviation = 0.1288

(d) We have to find the probability that the difference in sample proportions (senior - junior) of students with parking passes is greater than 30%.

The test statistic, z = Mean - delta/√P'(1- P')*(1/n1 + 1/n2)

z = 0.23 - 0.30/0.1288

z = -0.56

The p-value is 0.7118. [Using NORMSDIST(z-value)]
