15. What is the mathematical average of the number of weeks in a year, seasons in a year, and the number of days in January?

This is what I know so far:
I know there is 52 weeks in one year.

I forgot to give you the choices:

A.36
B.33
C.32
D.31
E.29

So -- which is YOUR choice?

To find the mathematical average, you need to correctly identify the number of weeks in a year, seasons in a year, and the number of days in January.

You are correct that there are 52 weeks in one year. Now let's find out the number of seasons in a year and the number of days in January:

1. Number of seasons in a year:
Traditionally, there are four seasons in a year: spring, summer, autumn, and winter.

2. Number of days in January:
January has a fixed number of days, which is 31.

Now that you have all the necessary information, let's calculate the mathematical average:

Number of weeks in a year: 52
Number of seasons in a year: 4
Number of days in January: 31

To find the average, you will add up these three numbers and divide the sum by 3:

(52 + 4 + 31) / 3

Calculating the sum: 52 + 4 + 31 = 87

Dividing the sum by 3: 87 / 3 = 29

Therefore, the mathematical average of the number of weeks in a year, seasons in a year, and the number of days in January is 29.
