The regression equation relating high school gpa (x) and college gpa (y) for 100 randomly selected fau students is y = 0.57x + 0.82. use the equation to determine the college gpa of a student whose high school gpa is 2.5. round your answer to two decimal places. (2 points)

a. 3.89
b. 2.62
c. 2.25
d. 1.17

c. 2.25

Step-by-step explanation:

The expression that relates high school GPA (x) to college GPA (y) is:

To find the college GPA of student whose high school GPA is 2.5, simply plug in the value x=2.5 into the expression above:

This student's college GPA is 2.25

the answer will be the last one

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
