<span>Arithmetic mean is used to describe the sum of values in a dataset divided by the number of values. It s the average of a given dataset which gives us an idea about the average value in a data set. That said, a mean of 4.3 means in the household sample (the average number of students in the data set falls within probably 4 and 4.7 probably). On the other hand,.a mean of 4.5 means there are more 8th graders than 7th graders. An increase of 0.2 from the 4.3 shows that the number of 8th graders slightly surpasses 7th graders.

Answer:
y=0.6x
(a)$43.20
(b)$1416.67
Step-by-step explanation:
Let:
- The amount raised during fundraising activities= m
- The amount the foundation will receive =n
The club donates 60% to the foundation.
Therefore, the amount of money the foundation will receive
n=60% of m
n=0.6m
(a) If the club raised $72
m=$72
n=0.6*72
The amount of money the foundation will receive, n=$43.20
(b)If the foundation received a cheque of $850
n=$850
Therefore:
850=0.6m
m=850/0.6
m=$1416.67
The club raised $1416.67 in total for the year
