Robert has scored an 88, 92, 83, 79, and 87 on his last five rounds of golf. What must he shoot on this sixth round to have a mean of 85?

Step-by-step explanation:

Robert has scored:

88+92+83+79+87+x=(85*6)

429+x=510

x=510-429=81

he needs to score an 81

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

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
