Change ∆ABC by moving point B to set m∠BCA to the values in the table. As you move point B, you’ll notice that a defect, or a rectangular area, is formed either within or next to square a2 and square b2. Calculate and record the areas listed in the table to two decimal places for each measure of ∠BCA.

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
