Choose the statement that is true and has a converse that is also true. O A. If the equation of a line is y = 3x + 2, then the slope of the line is 3.
O B. If x2 = 100, then x = 10.
O c. If x – 1= 8, then x = 9.
O D. If an angle measures 45 degrees, then the angle is acute.

Using the quadratic formula find the zeros of the given polynomial -5x^2+3x-11

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
