The table compares x, the number of minutes of television sam watched each day, to y, the number of minutes she spent exercising. the function y = –0.78x + 95 models the data in the table. which is the best prediction for the number of minutes of exercising sam will do if she spends 30 minutes watching television that day? 45 minutes 72 minutes 83 minutes 118 minutes

"The function y = –0.78x + 95 models the data in the table. Which is the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day?"

Just substitute 30 for x in the given function: f(30)= -0.78(30)+ 95.

71.6. She will exercise for about 72 minues on that day.

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
