Its quick i just need with this one that im stuck on

discriminent worksheet

a: -4 ex: -4m^2-3m+3=-6
+6 +6

b: -3

c: 9 .

-4m-3m+9=0

b^2-4ac

(-3)^2-4(-4)(9)

9+144

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
