Brainliest + 40 points! use this linear regression equation y = 17.4 + 4.8 ⋅ x use that equation to predict the scores for two people who studied for 15 hours and 9 hours.

y=17.4 + 4.8x

I will assume x is the hours

y = 17.4 + 4.8 (15)

y = 89.4

y = 17.4 + 4.8 (9)

y = 60.6

9 x 8 divided by (5-3)=36

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
