Which is the correct first step in finding the area of the base of a cylinder with a volume of 140 pi cubic meters and a height of 12 meters?
V = B h. 12 = B (140 pi)
V = B h. V = 140 pi + (12)
V = B h. V = 140 pi (12)
V = B h. 140 pi = B (12)

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
