Bernice is trying to estimate her costs of driving a car. She makes a $350 per month car payment. In addition, it costs $.20 per mile to maintain the car and provide fuel. Complete the table below so that you can answer the next 3 questions. # of Miles Driven Process Cost in Dollars 100 200 300 400 500 What is an equation that can be use to model this situation? O c = 0.20m - 350 O c = 0.20m + 350 Oc=350m - 0.20 O c = 350 +0.20

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
