Anton is seeking an advanced degree that requires an investment of $70,000 and a three-year commitment during which he will lose $20,000 a year in income. Even without considering the interest lost on the investment and lost earnings, how long will it take him to recover his investment if he makes $10,000 more per year after completing the degree?

Define multiplicative inverse. give an example of a number and its multiplicative inverse.

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

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
