Answer:
<h2>288 ft³</h2>
Step-by-step explanation:
The formula of a volume of a prism:

where
<em>B</em><em> - area of a base</em>
<em>H</em><em> - height of a prism</em>
<em />
In the base we have the right treiangle. The formula of an area of a right triangle is:

where
<em>a, b</em><em> - are legs</em>
We have

Substitute:

Calculate the volume.
Substitute


The volume of the original cube = 18^3 = 5,832 cubic cm
5,832 / 8 cubes = 729 cubic cm.
Side length = Cubicroot729 = 9
The side length is 9 cm
Answer: 99% confidence interval would be (45.74,54.26).
Step-by-step explanation:
Since we have given that
N = 18
Mean = $50
Standard deviation = $7
At 99% confidence level, z = 2.58
So, Interval would be

Hence, 99% confidence interval would be (45.74,54.26).
Answer:
yes, i agree. the right angle is 90 and 90+90=180. The law of the congruent angle states that if one angle in a the plane is right then the other connected must be as well, making line L 180.
Step-by-step explanation:
i badly explained it however you should get the answer correct with that. i think... use your brain in addition to mine.
