Answer:
Step-by-step explanation:
plug in 3 , 5 and 17 for n
8 + 3(3 -1) = 8 + 6 = 14
8 + 3(5-1) = 8 + 12 = 20
8 + 3(17-1) = 8 + 48 = 56
The mean is 8 gerbils and the MAD is 4.29.
<h3>What is the mean?</h3>
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
(0 + 3 + 6 + 9 + 11 + 13 + 14) / 7 = 8
What is the MAD?
MAD = ∑ l x - m(x) l
| (0 - 8) + (3 - 8) + (6 - 8) + (9 - 8) + (11 - 8) + (13 - 8) + (14 - 8)| / 7 = 4.29

The correct answer is 14/15. To answer this problem, it would help to change the mixed number into an improper fraction.
1 1/3
4/3 Multiply 3 by 1, and then add 1 and put 4 over 3.
4/3 x 7/10 Now, multiply both numbers by each other. Since we're multiplying, we don't need to find a least common denominator.
28/30 4 x 7 = 28; 3 x 10 = 30
14/15 Since 28 and 30 are divisible by 2, we need to simplify the answer.
The correct answer is 14/15.
Hope this helps!
