A squirrel can run a short distance at a rate of 4 3/4miles in 15 minutes. A fox can run a short distance at a rate of 21 miles in half an hour. Which
is faster, and how much faster in miles per hour?

Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

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
