Answer:

The residual e=2 when x = 5.

Step-by-step explanation:

A scatter plot containing the point (5, 29), it means the observed value at x=5 it 29.

The given regression equation is

\hat{y}=5x+2

Substitute x=5 in the above regression equation, to find the predicted value at x=-5.

\hat{y}=5(5)+2=25+2=27

The formula to find the residual value e is

e = Observed value - Predicted value

e=29-27

e=2

Therefore the residual e=2 when x = 5.

Delvig [45]
Substitute the 1st equation in the 2nd, we get:

3x + 2(-3 + 2x) = 2
3x -6 +4x = 2

7x = 8
x = 8/7

Replace x = 8/7 in equation 1,

y = -3 + 2(8/7) = -3 +16/7 = -5/7
