First calculate the mean:

\text{mean}=\frac{12+10+10+8+6+7+7+12}{8}=9

Next c<span>alculate the distance between each data point and the mean, and add them together. We get:

</span>|12-9|+|10-9|+ |10-9|+|8-9|+|6-9|+2*|7-9|+|12-9|\\&#10;=16&#10;
<span>
Take this number and divide with the number of observations:

</span>\text{MAD}=\frac{16}{8}=2<span>

Alecsey [184]

Answer:

50/b in

Step-by-step explanation:

Use the area formula A = (1/2)(base)(height).

Here the area A is given and is 25 in^2; the base is not given, so use 'b.'

Then, since A = (1/2)(base)(height),

(height) = 2A/(base) = 2(25 in^2)/b = 50/b in
