Answer:
0.156
Step-by-step explanation:
Given that :
% of Explained variance by certain predictors of first year college grade :
SAT 11 scores = 17%
GPA = 15.6%
SAT 1 = 13.3%
Fitting a least squares line :
y = First year college GPA
x = high school GPA
THE r² value which is Coefficient of determination is the percentage of explained variance given by the regression line. The r² value of GPA will the as given above 15.6%
r² = 15.6% = 15.6/100 = 0.156
Answer:
If you invest there is a chance your money will gain value, leaving it and saving it will make the money slowly lose value from inflammation, This makes it a pretty difficult choice as if the stocks crash James loses a lot of money but, it can rise in value it will be worth it.
im saying invest it.

Answer:
Step-by-step explanation:
1) First, find the slope of the line. Take two points the line intersects and use them for the slope formula, 
. We already know the line intersects (-4, -2). Just choose any one of the points you can see the line intersecting (in this case, I chose (0,3)) and plug in its values, too. Then solve:
So, the slope is 
.
2) Now that you have the slope, plug in values for the point-slope formula, 
. In order to write a linear equation with it, the 
, 
, and 
have to be substituted for with real values. The represents the slope - which means that we should place there. The and represent the x and y values of a point - and the questions wants us to use (-4, -2), so substitute -4 for and -2 for :
Thus, the answer is .
The area of the given triangle is 25 square cm.
Step-by-step explanation:
Step 1:
First, we plot the coordinates of the triangle.
The right bottom end of the triangle is at (15, 5).
The bottom left end of the triangle is at (10, 5).
The top left end of the triangle is (10, 5).
The area of a triangle is given by half the product of its base length and the height of the triangle.
Step 2:
The area of a triangle
The base is the distance between the bottom two points. The base length
cm.
The height is the distance between the two left points. The height
cm.
The area of the triangle 
The area of the given triangle is 25 square cm.
