Suppose the average height of a sixth-grader is 60 inches and the standard deviation is 2 inches, and assume that the heights are normally distributed.
1. The percentage of sixth-graders between 54 inches and 66 inches tall is
2. The percentage of sixth-graders between 56 inches and 64 inches tall is
3. The percentage of sixth-graders between 58 inches and 62 inches tall is

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

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
