A coffee roaster is designing a coffee can that can be modeled with a right cylinder for its new Breakfast Blend. Breakfast Blend costs the roaster $0.03 per cubic inch to produce. The roaster wants the can to contain an amount of
coffee that will cost him no more than $7.50 to produce. Given that the height of the can is to be equal to its diameter,
what is the maximum height allowable for the can? Round to the nearest tenth of an inch,

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
