Pretend you are coaching a sports team-you pick the sport. What are some ways you would use matrices on the job?

A matrix is basically a table of columns and rows. One way to use an array is to tabulate information concerning two variables, for example, sizes of shoes and person's height, or price of different kinds of vegetables over 12 months, etc. So for your problem, think of two variables that you can tabulate in your sports team.
