To find the mean, you add all the numbers together and then divide by the number of numbers (6).
4 + 12 + 20 + 24 + 32 + 40 = 132
132/6 = 22
To find the mean absolute deviation, you will find the distance between each number and the mean and then divide this by 6 as well.
(22-4) +(22-12)+(22-20)+(24-22)+(32-22)+(40-22)
18 + 10 + 2 + 2 + 10 + 18 = 60
60/6 = 10
The mean absolute deviation is 10.
The correct answer is that Stefano should have divided by 6 when finding the mean absolute deviation.

Answer: 819.73 yd²
<u>Step-by-step explanation:</u>
=
=
= 29 * 30
= 870
= π(4)²
= 16π
≈ 50.27
Area of the park =
= 870 - 50.27
= 819.73
Step-by-step explanation:
set up a proportion for a.
225/30=x/195. x=1462.5 milligrams daily
for b, if he gets 700 mg every 8 hours he only gets it 3 times a day. 700*3 is 2100, which means he is overdosing
The theorem is: a^2 - b^2 = (a+b) (a-b)
So, let's do this:
64x^2 - 49=
(8x)^2 - (7)^2=
(8x+7) (8x-7)
