4) Check all the equations below that are equivalent to:
3(2+1) = 15 - 26
(Select all that apply)
3+3(1+t) = 15 - 26
6+ 3t = 6 + 70-5t+ 9
3(2+1) +7= 15 - 20 + 7

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
