The right response is C. Only X-values inside the original data's range give meaning to the prediction values.
A statistical model that depicts the relationship between two variables is a regression line. It is utilized to forecast the value of a dependent variable depending on the value of an independent variable (independent variable).
The degree to which the regression line matches the data determines how accurate these forecasts are. For values of the independent variable that are similar to the values used to fit the model, the regression line will typically offer the most precise predictions. Prediction values therefore typically only have significance for X-values that fall within or very near the range of the original data set.
The predictions might not be correct if you use the regression line to construct them for independent variable values that are far outside the original data range. This is because, outside of the range of the data that was used to construct the model, the model may not effectively represent the connection between the two variables.

14. Jackie borrows $1,500 at 5.75% compound
interest for five years. If she makes monthly
payments, how much is her loan amount after
five years? Round answer to the nearest dollar.
[A] $1,536
[D] $1,725
[B] $2,073
[E] $1,998
[C] $2,050
16 Robert
To find the loan amount after five years, we need to calculate the compound interest on the loan. The compound interest is calculated by multiplying the principal (the initial amount borrowed) by the compound interest rate, raised to the power of the number of compounding periods. In this case, the compound interest rate is 5.75%/12 = 0.475% per month, and there are 12*5 = 60 compounding periods (12 months per year for 5 years).
The compound interest is therefore calculated as follows:
Compound interest = $1,500 * (1 + 0.475%)^60 - $1,500
= $1,725 - $1,500
= $225
So the loan amount after five years is $1,725. Therefore, the correct answer is [D] $1,725.

When they buy 125 identical stuffed animals for $312.50 and sell them for $7 a piece, the percent markup is 64.2%.
What is percentage?A percentage is a figure or ratio that may be stated as a fraction of 100 in mathematics. If we need to compute the percentage of a number, divide it by the entire and multiply by 100. As a result, the percentage denotes a part per hundred. The term % refers to one hundred percent. The sign "%" represents it. To compute a percentage, divide the value by the entire amount and multiply the result by 100. (value/total value)100% is the formula for calculating percentage.
Here,
Total cost=$312.50
Total sell price=7*125

the distribution of salaries of teachers is approximately normal. which measure of central tendency would be the best measure to determine the location of the center of the distribution?
The best measure of central tendency to determine the center of the distribution of teacher salaries is the mean.
The mean is the average of all values in a set and is calculated by adding up all the values and dividing them by the number of values. This measure is particularly useful for data that follows a normal distribution, as teacher salaries are likely to do.
The mean is the most commonly used measure of central tendency and is a good indicator of the center of the data set. It is also relatively easy to calculate. So mean will be the measure of the central tendency to determine the center of the distribution of teacher salaries.

alex is x years old. june is 7 years older than alex. in 5 years, their total combined age will be 31 years. write a linear equation for their total combined age in 5 years
The linear equation for their total combined age in 5 years is 2x + 17 = 31.
Describe the term linear equation?A linear equation is indeed an algebraic expression of the form y=mx+b, where the slope is m and b is the y-intercept, and only a constant and the first-order (linear) term are included.Let the age of Alex be x years old.
Let the age of June be 'y'.
June is exactly 7 years older than Alex.
y = x+7
In next 5 years, combined total age will be of 31 years.
(x+5) + (y+5) = 31
Now, the linear equation that models total combined age in 5 years
Replace y with (x+7)
x + 5 + (x+7) + 5 = 31
2x + 17 = 31

How to find the price of the microwave?Javier bought a microwave for $105. The cost was 30% off the original price. Therefore, the price of the microwave before sales can be calculated as follows:
let
x = price before sales(original price)
Therefore,

Arithmetic operations can be used to solve this question by using the topic of order of operations. We need to use × and - operators to get the correct answer.
How do we solve inequalities using Arithmetic operations?Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains. However, these factors will shift the direction of inequality: Using a negative number to multiply or divide both sides. switching the left and right sides. When resolving an inequality, you can do one of the following:
• Add the same amount to each side;
• Subtract the same amount from each side;
• Multiply or divide each side by the same positive amount. You must flip the inequality sign if you multiply or divide each side by a negative number.
Calculation:5 x (23-18) x (8-4)=100
So we can subtract 23 from 18 where we will get 5 and by subtracting 4 from 8 you will get 4. By multiplying the numbers using × operator you will get the final answer.
