Answer:

Step-by-step explanation:
The volume of the pyramid is given by:

where
is the area of the base and
is the height.
We know that the height is:

Thus we need to find the area of the square at the base.
The perimeter of the square is:

this means that the length of the sides of the square is :

Now we can find the area of the base which the area of the square:

and finally we find the volume:


Which rounded to the nearest tenth of a cubic centimeter is: 
Slope= 5
X-intercept= -5/5 = -1
Y-intercept= 5/1 = 5.0000000
Answer:
(8 x 9) x (2 x 5) is the correct answer.
Step-by-step explanation:
(8 x 9)= 72
(2 x 5)= 10
72 x 10 = 720
Standard deviation = √(n * p * q)
You are given n and p
q = 1 - p
q = 1 -0.2 = 0.8
Standard deviation = √(21 * 0.2 * 0.8)
=√3.36 = 1.83
The answer is A.
