Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

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
