The area of a square is found by squaring one of its sides, (a = s2). a certain square has an area of z2 + 18z + 81. factor the trinomial to find a side of the square.
a. side = z + 27
b. side = z + 18
c. side = z + 9

For what value of (y) is 3^3/3^y =1/9

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
