Answer:
A U B = {2,3,4, 5}
Step-by-step explanation:
Union means join together
A U B = {2,3,4, 5}
Volume for a cylinder is πr^2h
radius is just the diameter divided by 2, so your radius is 1
πx1^2x5=5π
= about 15.71 inches^3
(70 -100)/15 = -2 . . . . the z-score of a score of 70
p(z < -2) ≈ 2.3%
A score of 70 would place you in approximately the 2nd percentile.
It will cost her $8.55 at $4.75 a pound
1/6 because the first number that you roll doesn't matter so it depends on the 2nd roll, in which the probability of rolling a specific number is 1/6
