The volume of milk in a pitcher is proportional to the depth of the milk. When there are 200 mL of milk in the pitcher,
the depth is 8.4 cm. To the nearest milliliter, how much
milk is in the pitcher when the depth is 19 cm?

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
