Consider the problem of washing dishes by hand. suppose washing a dish takes 30 seconds and drying a dish takes an additional 30 seconds, and we want to find out the time to wash 11 dish. if the the size of a problem is represented by n. what is the value of n in the given problem?

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
