How could the relationship of the data be classified?

a. a fairly strong positive correlation
b. a fairly weak positive correlation
c. a fairly strong negative correlation
d. a fairly weak negative correlation

That would be a fairly weak positive correlation.

Step-by-step explanation:

If you start in the origin and go up, the correlation is positive.

This would be fairly weak because the points are pretty scattered. If it were strong, you could almost draw the line of best fit by yourself. Here you can't.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
