Answer 1

20 is the answer ihope this helllllllllllps

Answer 2

Answer:

e=20

Step-by-step explanation:

Given there is a scatter plot.

A point on it is (10,7)

The regression line y' = -x-3

We have regression line giving estimate for given value of x

When x=10, actual value of y

= y observed = 7 (given)

As per regression line estimate

y = -10-x = -13

Difference between y estimate and actual y = 7-(-13)

=20
