Suppose we lined up all the people in the world (about 7.4 billion people). Assume that each person occupied 16 inches of the line. How many times around Earth would they reach? (Earth has a circumference of about 25,000 miles.)

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Select the sequences that are geometric.
