The mean of a data sample can be found by adding all the terms in the data sample and dividing the result by the number of terms. In the first case we have the following data sample:

12,8,15,11,9

The mean of this sample is:

\operatorname{mean}=\frac{12+8+15+11+9}{5}=\frac{55}{5}=11

The mean absolute deviation is the sum of the differences between each data value and the mean, divided by the number of data values, the formula is:

MAD=\frac{\sum ^{}_{}\mleft|x_i-\bar{x}\mright|}{n}

Therefore, we must calculate the positive difference between each value and the mean, add them up, and divide the result by the number of data points in the sample. In the case of the first sample we get:

\text{MAD}=\frac{(12-11)+(11-8)+(15-11)+(11-9)}{5}

Solving the operation:

\text{MAD}=\frac{10}{5}=2

If done this way, all the results for each data set must be correct.

A 185-pound person burns 260 calories during a soccer game. Find the number of calories that a 250-pound person would burn durin
Olin [163]

Answer: The answer to this problem is 178 calories.

Step-by-step explanation:

To calculate the answer, simply get the percentage of calories a person would burn during exercise (I am using a calculator BTW).

185 / 260 = 0.711538462

Then, calculate 71.1538462% of 250 pounds.

250 * 0.711538462 = 177.884616

Finally, round up your answer. 177.884616 rounded up is 178.
