The concentration C(t) of a certain drug in the bloodstream after t minutes is given by the formula C(t)=0.08(1−e−0.1t). What is the concentration after 10 minutes? Round to three decimal places.

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
