As a large truck fills its gas tank, the volume of gas, in gallons, can be modeled with the linear function 4.88.2vm , where v is the volume of gas and m is the number of minutes it has been filling. Give a physical interpretation for both the 4.8 and 8.2 parameters in the linear model. Use appropriate units in your explanation.

Cherie measures and records the lengths and sizes of the same style of a sandal found at a shoe store. which equation can be used to determine the approximate shoe size, s, for a foot length of x inches? s = x – 2 s = 2x – 10 s = x + 6 s = 2x + 4

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
