Answer:
Carrie's slope value is correct.
Step-by-step explanation:
The least square regression line is: 
Here 
is the slope of the line.
The formula to compute the slope is:
Here 
= standard deviation of <em>x</em> and 
= standard deviation of <em>y</em>.
It is provided that the standard deviation of <em>x</em> and <em>y</em> are equal.
So the slope of the regression line is:
Thus, if the standard deviation of <em>x</em> and <em>y</em> are equal the slope of the line is same as the correlation coefficient.
The correlation coefficient is a measure used to determine the strength of the linear relationship between the variables.
It ranges from -1 to 1.
Carrie's slope value was 0.50 and Ryan's slope value was 2.
Since -1 ≤ r ≤ 1 the value of slope cannot be 2.
Thus, Ryan's slope value is incorrect.

a=7+3+7=17
b=3
h=8
area=(1/2)(17+3)(8)=80
Answer: The answer is (D) auto insurance agency.
Step-by-step explanation: We are given four options out of which we are to select the one which a basic loan application would not ask us for.
We know that a basic loan application always needs to know some information like name, date of birth, social security number, address, etc.
What it does not need is auto insurance agency, because they do not need any information about this.
Therefore, the correct option is (d) auto insurance agency.
Step-by-step explanation:
You use the I = PRN formula
P = 11 500
R = 7.25% but you have to 7.25 divide by 100 so it becomes a decimal so it should be 0.0725
N = 2 years and 6 months. This can be 2.5 years because half of 12 is 6
the solution is 11 500 × 0.0725 × 2.5 = 2084.38
Answer:
$125,500
Step-by-step explanation:
Make "x" equal the selling price of the house
7% of x is the commission --->
.07 * x = 8785
x= 8785/ .07
x= 125500
