What is the slope of this line?
y = -4x + 7
a: 4
b: 7
c: -4
d: -7

Assume cd | ab are parallel. find m2. a) x= 50° (b) x = 70° c) x = 30° d) x = 60

What is the slope of a line that is perpendicular to y = 3x + 1

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
