4. The drag force, F (in pounds), of water on a swimmer can be modeled by F=1.35s2, where s is the swimmers speed (in miles per hour). How fast must you swim to generate a drag force of 10 pounds?

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
