Answer: The shortest is 14 in. the longest is 22 in. and the middle is 20 in.
Step-by-step explanation:
To find the mean of a number sequence, add all the numbers together and divide them by the number of numbers used...
10 + 11 + 10 + 10 + 8 = 49
49 ÷ 5 = 9.8
The mean does not match 10, so make up numbers untill it matches.
10 + 11 + 10 + 10 + 8 + 6 ÷ 6
= 10 !
The anwser would be y = 6
You divide the 15x by the 124. I know it sounds weird because you'll get a decimal, but that is what you are supposed to do because 124 is not a factor of 5.
