ratio of perimeter is the same as ratio of sides so perimeter would be 1:4
since area is in square units you need to square the ratio (1:4)^2 which is 1:16
The mean of the data without the outliers will be B 65.
Yea. The text book is either wrong or it knows something that we don't. Like as to why they would need to have two more feet. You're right though
We apply the following property:
(x^n)^m = x^(n • m)
Let m = 2
(P^1/2)^2 = P^(1/2 • 2) = P
The answer to your question is 0.6 you really should have made it longer
