To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
<h3>What is the average?</h3>
Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
- 69 seconds.
- 58 seconds.
- 45 seconds.
- 120 seconds.
- 76 seconds.
The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

Since we have the endpoints of a diameter the center is very easy to find. It is the midpoint of the diameter endpoints, which is just the average coordinates...
The center is:
((-7+3)/2, (-10+2)/2)
(-2,-4)
To find the radius we can use the endpoints again to find the diameter squared and then get the radius from that:
d^2=(dy)^2+(dx)^2
d^2=(2--10)^2+(3--7)^2
d^2=12^2+10^2
d^2=144+100
d^2=244
d=√244, since d=2r, r=d/2
r=√(244/4)
r=√61
The equation of a circle is (x-h)^2+(y-k)^2=r^2. We found earlier that the center was at (-2,-4) and we just saw that r^2=61 so:
(x+2)^2+(y+4)^2=61
