A student survey studied the amount of time students spent watching TV and exercising. Let yequalsexercise and xequalswatch TV. One student reported watching TV an average of 150 minutes a day and exercising 90 minutes a day. This person's residual was 48.1 and standardized residual was 3.45. a. Use the residual to find the predicted value of exercise. ModifyingAbove y with caretequals nothing

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

130 degrees. i have no other way to explain
