It costs $100 to rent the bowling alley, plus $4 per person. the cost for any number (n) of people can be found using the expression 100 + 4n. the cost for 15 people equals !

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

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
