Asap the weights of the watermelons in a local grocery store is normally distributed. the mean weight is 18 pounds with a standard deviation of 1.5 pounds. how much do the middle 95% of the watermelons weigh? between 15 and 21 pounds between 16.5 and 19.5 pounds between 13.5 and 22.5 pounds between 17.1 and 18.9 pounds

Since it's normally distributed, we can apply the emperical rule. The middle 95% will be within two standard deviations of the mean, so that means:

18-2(1.5), 18+2(1.5)=15,21

So we want the first option.

step-by-step explanation:

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
