Answer:
52x + 26y + 20z
Step-by-step explanation:
Assuming you needed the answer to be simplified!
First, you would find the mean of the data. Once you have the number, you would find the difference between the mean and the other numbers. Once you have all of those numbers, you find the mean of that set. For example:
The mean of this set is 9. We then use this number to find the difference between all of the numbers. So 14-9= 5, 9-7=2, 9-6=3, 9-5=4, 13-9=4. Finding the mean of 5, 2, 3, 4, and 4 results in 18/5 or 3.6
3.6 is the mean absolute deviation.
The improper fraction is 31/8
The answer is D because if the scale length is if 1 in is 6 ft and if there is 12ft it has to be D bc 2 in is 12 ft
