A solid whose top and base are congruent polygons and lateral faces are parallelograms is called <u>prism</u>.
<h3>
What is prism?</h3>
A prism is a polyhedron made up of n parallelogram faces that connect the n-sided polygon basis, the second base, which is a translated duplicate of the first base, and the n faces. Translations of the bases are found in all cross-sections that are parallel to them.
<h3>What is
congruent polygons?</h3>
If the corresponding sides and angles of two polygons are identical, then the polygons are congruent. It should be noted that two sides are congruent if their lengths are the same, and that an angle is congruent if its measure is the same.

I understand that the question you are looking for is:
A solid whose top and base are congruent polygons and lateral faces are parallelograms is called _____.
A. prism
B. polyhedron
C. sphere
D. cone
(i) The mean is

The variance is

Compute the second moment
:

Then the variance is

(ii) For a random variable
, where
are constants, we have

and

Then for
, we have


Distribute the 2 through the parentheses
on the right side of the equation.
2(y) is 2y and 2(2) is 4.
So the problem now reads 6 = 2y + 4.
Now we can subtract 4 from both
sides of the equation to get 2 = 2y.
Now divide both sides of the
equation by 2 and <em>1 = y</em>.
Answer:
i dont know
Step-by-step explanation:
48 divided by 16
Let n represent the number.
"the sum of a number and 7" is (n+7)
Three times "the sum of a number and 7" is 3(n+7)
"is" translates to "=".
"five times the number" is 5n
Two less than "five times the number" is 5n-2
Your equation is
3(n+7) = 5n-2
