Asap explain how to solve step by points a and b are on opposite sides of a lake. a point c is 81.3 meters from a. the measure of angle bac is 78.33°, and the measure of angle acb is determined to be 34.167°. find the distance between points a and b (to the nearest meter).

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
