Answer:

Mean = -1,115,000 per year.

Step-by-step explanation:

A team won 9 of its first 12 games. At that rate, how many games will the team win if it plays 64 games in all?
Feliz [49]
9 out of 12 = 9/12 which can be simplified to 3/4.  So the team wins 3/4 of its games.  3/4 of 64 = 64 divided by 4 = 16.  16 x 3 = 48.
