Given a circle q, (x-1)^2+(x-2)^2=9 a, determine the shortest distance between the point p(5, -2) and the circle q b) write the equation of the circle centered at point p that is just tangent to circle

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
