The graph shows the best-fit regression model for a set of data comparing the number of hours spent hiking and the number of miles traveled in one day.

A) Each point in the data set falls on the regression line.

B) The regression model is an accurate representation of the distance for any number of hours hiked.

C) Each point in the data set is near the regression line.

D) The regression model is inaccurate, as it does not begin at (0, 0).

d)

Step-by-step explanation:

it does not begin at 0,0

it is beginning at the 1

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
