A weather station on the top of a mountain reports that the temperature is 0°C currently and has been falling at a constant rate of 5°C per hour. What will the temperature be in 2 hours if the temperature continues to fall at this rate?

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
