The scatter plot below shows one class of Spanish students’ time spent studying for their final versus the grade that they earned on the final. If a student studies for 75 minutes, what is the best estimate for his or her grade? A.100
B.90
C.45
D.75

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

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

is there supposed to be a diagram or a graph for this one? ?
