Answer: (1.55, 6.45)
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given : Significance level :
Critical value :
Sample size : n=41
Sample mean :
Standard deviation :
Then, 99% confidence interval for population mean will be :_
The squiggly lines and the 2 straight lines through to sides of the pentagon mean that they are congruent (equal in length).
So, to find the perimeter of a regular polygon, you add all of its sides together.
So, the perimeter= 4x-2+x-2+x-2+x+2+x+2
To simplify it, add all of the x's together.
4x+x+x+x+x=8x
Perimeter=8x-2-2-2+2+2
-2-2=-4-2=-6+2=-4+2=-2
Perimeter=8x-2

V = 2s^3
v = 2(3.5)^3 = 2(42.875) = 85.75 cubic units
In any triangle, the longest side is the one that is opposite the largest angle.
Therefore, the longest side is "a".
