An ant crawls at a rate of 2 1/6 ft per minute. at this rate, how long does it take the ant to crawl a distance of 5 1/5 ft?
enter your answer as a mixed number in simplest form.

(p. s, the numbers 1/6 and 1/5 are fractions. do not think of them as dividing.)

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
