I think you mean Mean Absolute Deviation or MAD. It means the average amount the digits are from the mean, so let's say the mean is 4 and the digits are 2, 6, 4. So find the difference of each digit 4-2=2 6-4=2 and 4-4=0. So you have 2, 2, 0. Now find the mean of those 3 numbers which will be 4/3.
The answers are...
a) -3
b) 6
c) 17
B=4 (: <3 Please put mine as branliest (:
Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.

Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:

r= 10 ft

Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
