PLEASE HELP ME :)) The equation c=25x + 150 represents the cost, c, of making x televisions for company A. The equation c=15x + 250 represents the cost of making televisions for company B. How will the graph from company A differ from the graph of company B?

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
