A stunt driver for the Dukes of Hazzard drove the General Lee off a ramp and landed on the ground a few seconds later. His height in feet is given by h=−16t^2+16t+50
where t is the time in seconds.
​
​What was the height of the ramp in feet?
​What was the maximum height in feet achieved?

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
