Ivan

The total possibilities can be 756 ways.

<h3>What is combination?</h3>

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order. Combinations can be confused with permutations.

Given:

The number of ways in which we can select atleast 3 men in the committee are 756.

Number of men = 7

Number of women = 6

Number of people that should be selected in the committee = 5

Now,

N(M = 3) = 7C_3* 6C_2

=35*15

=525

N(M = 4) = 7C_4* 6C_1

=35*6

=210

N(M = 3) = 7C_5* 6C_0

=21*1

=21

So, total possibilities can be = 525 + 210 + 21 = 756 ways.

The length, width, and height of a rectangular prism is a, (a-13), and (a+13) respectively, which statement best describes (a-13
Nitella [24]

Answer:

a. The width of the rectangular prism is 13 units less than the length.

Step-by-step explanation:

From the information given we know that

a = length of rectangular prism and

a - 13 =  width of rectangular prism

An expression like a - 13 means that we need to subtract 13 units from the length to obtain the width of the rectangular prism.

Therefore,

The width of the rectangular prism is 13 units less than the length.
