IMPORTANT STUFF: 1. (This problem is a continuation of the opener from Small Group.) The graph below represents a car
race between Chandler, Joey, and Ross,

(a) What is the approximate speed of each person during this race? You are allowed to estimate the
locations of points on the grid.

Write a corresponding real world problem to represent 2x - 125=400

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
