X 2x+y=5
2x + y = 5 Equation
3x - 2y = 4 Equation 2
Step 2:
Step 1:
2x + y = 5
y = -2x + 5
2x + (-2x + 5) = 5
2x - 2x + 5 = 5
5 = 5

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
