We can estimate that approximately 14.17% of students in the district are interested in playing hockey.

Total interested students = 0.1417 x 4,000 = 567.

An average proportion is the sum of a set of proportions divided by the number of proportions.

It represents the average or typical value of the proportions in the set, and can be used to estimate the overall proportion or percentage of a larger population

To estimate the total number of students in the district who are interested in playing hockey, we can first find the proportion of students in each sample who said yes, and then use the average proportion across all four samples to estimate the proportion of students in the district who are interested.

Finally, we can multiply this proportion by the total number of students in the district to estimate the total number of interested students.

The proportion of students in each sample who said yes is:

Sample 1: 4/30 = 0.1333

Sample 2: 5/30 = 0.1667

Sample 3: 5/30 = 0.1667

Sample 4: 3/30 = 0.1000

The average proportion across all four samples is:

(0.1333 + 0.1667 + 0.1667 + 0.1000) / 4 = 0.1417

To estimate the total number of interested students, we can multiply this proportion by the total number of students in the district: Total interested students = 0.1417 x 4,000 = 567.

Step-by-step explanation:

Assuming the $60 is excluding taxes:

60 * 1.055 = $63.30

Δy=v-0.32 and dy = -0.32 .Δy and dy are both used to represent changes in the dependent variable y based on changes in the independent variable x.

Δy represents the change in y (the dependent variable) resulting from a specific change in x (the independent variable). In this case, y = x^4 + 7, x = -2, and Δx = dx = 0.01. Therefore, we need to calculate Δy and dy based on these values.

To calculate Δy, we substitute the given values into the derivative of the function and multiply it by Δx. The derivative of y = x^4 + 7 is dy/dx = 4x^3. Plugging in x = -2, we have dy/dx = 4(-2)^3 = -32. Now, we can calculate Δy by multiplying dy/dx with Δx: Δy = dy/dx * Δx = -32 * 0.01 = -0.32.

On the other hand, dy represents an infinitesimally small change in y due to an infinitesimally small change in x. It is calculated using the derivative of the function with respect to x. In this case, dy = dy/dx * dx = 4x^3 * dx = 4(-2)^3 * 0.01 = -0.32.

Therefore, both Δy and dy in this context have the same value of -0.32. They represent the change in y corresponding to the change in x, but Δy considers a specific change (Δx), while dy represents an infinitesimally small change (dx) based on the derivative of the function.

The cash value of Jim's policy at 15 years and 25 years are equal to $9,000 and $51,000 respectively.

From the table shown in the image attached below, we can deduce that the cash value per unit for 15 years is given as:

15 years = $160.00 per unit.

Next, we would divide the face value of the policy by 1000:

Number of units = 150,000/1000

Number of units = 150.

Now, we can determine the cash value:

Cash value = 150 × 160

Cash value = $9,000.

The cash value per unit for 25 years is given as:

25 years = $340.00 per unit.

Next, we would divide the face value of the policy by 1000:

Number of units = 150,000/1000

Number of units = 150.

Now, we can determine the cash value:

Cash value = 150 × 340

Answer:

15 years = 24,000.00

25 years = 51,000.00

Step-by-step explanation:

Hey, I'll explain how you solve these.

Since the value is 150,000, this has to be divided by 1,000.

That gives us 150.

Now you multiply 150 by the 15 yr cash value, which is 160.  

This results in 24,000.00.

Since you have 150, you next need to multiply that by the 25 yr cash value, 340.

That gives us 51,000.00.

The \(\( R^{2} \)\) value for this regression is 0.625, indicating a moderate level of goodness of fit. There is a significant mean squared error present, a considerable deviation between the predicted and actual.

The \(\( R^{2} \)\) value is a statistical measure used to assess the proportion of the variance in the dependent variable that can be explained by the independent variables in a regression model. In this case, the \(\( R^{2} \)\) value is 0.625, which means that approximately 62.5% of the variance in the dependent variable can be accounted for by the independent variables included in the model. This indicates a moderate level of goodness of fit, suggesting that the model captures a substantial portion of the relationship between the variables.

On the other hand, the mean squared error (MSE) measures the average squared difference between the predicted and actual values. A significant MSE implies that there is a substantial deviation between the predicted and actual values, indicating that the model's predictions may not be accurate. Therefore, despite the moderate level of goodness of fit indicated by the \( R^{2} \) value, the presence of a high MSE suggests that there may be room for improvement in the model's predictive accuracy. It is important to further investigate the causes of this error and potentially refine the model to reduce the discrepancy between predicted and actual values.

Answer:

this is correct:)

Step-by-step explanation:

One or more of the mean differences are statistically significant, but not the precise location of the group differences.

In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, might be an independent variable.

Dependent variables are so-called because, during an experiment, their values are examined on the assumption or presumption that they are governed by the values of other variables.

h(x) = -7/6x - 25/6.

Given h(-1)=-2 and h(-7)=-9

For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.

To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

h(-1) = -2 is a point on the line, so we can write it as (-1, -2).

h(-7) = -9 is another point on the line, so we can write it as (-7, -9).

Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6

Now we can find b using one of the points and m. Let's use (-1, -2):

y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b

b = -25/6

Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6

We can check our answer by plugging in the two given points:

h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9

The answer is h(x) = -7/6x - 25/6.

If a car goes 60 miles per hour then in two hours (60×2) it will go 120

A random variable is said to be continuous if it is measured over an interval. Option b. "is measured over an interval" correctly describes a continuous random variable.

A continuous random variable can take on any value within a given interval, including decimal values. It represents measurements that can be infinitely divided and can take on an uncountable number of values. Examples of continuous random variables include the height of individuals, the time it takes to complete a task, or the temperature of a room. These variables are not restricted to specific discrete values and can vary continuously.

On the other hand, discrete random variables (options a, c, and d) can only take on a countable number of distinct values. Discrete random variables represent outcomes that are distinct and separate, such as the number of students in a class, the number of cars passing by, or the number of heads obtained when flipping a coin.

These variables do not have decimal values and cannot be measured over a continuous range.

Answer:

c

Step-by-step explanation:

Some key definitions:

Reflexive property: angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.

Symmetric property: you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.

Transitive property:  If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.

So for the first clue, you have the reflexive property.

The second clue is the symmetric property.

The third clue is the transitive property.

Step-by-step explanation:

Using the formula of area of a circle, about 226.08in² has been eaten

The diameter of the pizza is given as 24 inches. To calculate the area of the entire pizza, we need to use the formula for the area of a circle:

Area = π * r²

where π is approximately 3.14 and r is the radius of the circle.

Given that the diameter is 24 inches, the radius (r) would be half of the diameter, which is 12 inches.

Let's calculate the area of the entire pizza first:

Area = 3.14 * 12²

Area = 3.14 * 144

Area ≈ 452.16 square inches

Now, if half of the pizza is consumed, we need to calculate the area of half of the pizza. To do that, we divide the area of the entire pizza by 2:

Area of half of the pizza = 452.16 / 2

Area of half of the pizza ≈ 226.08 square inches

Therefore, if half of the pizza is consumed, approximately 226.08 square inches of pizza would be eaten.

Answer:

Step-by-step explanation:

Givens

Student A

d = 3/4 mile

t =  6 minutes

Student B
