Can anyone help with an explanation

2 games total

Step-by-step explanation:

If i understand right you are supposed to count how many games were played in which case you would see there are 4 quarters, which is one game and then the home, and away game, giving you two games. Hope that helps!

Home Games:

You know the mean number of goals scored (in a game) is 2.5.

Add up the total number of home game goals scored:

    9 + 6 + 8 + 7 = 30

This means the 30 goals ÷ the number of home games = 2.5

Solve 30/x=2.5 to find that x=12.  30/12 = 2.5

Away Games:

Repeat the same process, but use the info for away games:

     2 + 7 + 4 + 5 = 18

18 goald ÷ number of away games = 1.8

Solve 18/x = 1.8 to find x=10.  18/10 = 1.8
