F\left( x \right) = 3x + 6f(x)=3x+6. Find the inverse of f(x). A.{f^{ - 1}}\left( x \right) = 6 - 3xf −1 (x)=6−3x
B.{f^{ - 1}}\left( x \right) = \frac{{x - 3}}{6}f −1 (x)= 6x−3
C.{f^{ - 1}}\left( x \right) = \frac{{x - 6}}{3}f −1 (x)= 3x−6

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
