Answer: The perimeter is 10.1415925, which you can round down to 10, or leave it as is.
Ryan is correct, the mean is about 8.1.
To find the mean, you have to add up all the values, then divide by the total amount.
For Sample A:
60 x 6 + 90 x 7 + 145 x 8 + 150 x 9 + 55 x 10 = 4050
If you add up all the adults, you have 500.
Dividing 4050 by 500 = 8.1
Sample B will produce a very similar result.
C is the correct answer
Since it says x-2 which is a horizontal translation and everything horizontal says you say the other way around. So left to you go right 2
