Ludmilka [50]

Answer:

There are 75 ways to form the committee.

Step-by-step explanation:

The order in which the people are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

Considering the eldest has to be there, 2 men from a set of 6 and 4 boys from a set of 5(excluding the youngest), so:

T = C_{6,2}C_{5,4} = \frac{6!}{2!4!} \times \frac{5!}{1!4!} = 3*5*5 = 75

There are 75 ways to form the committee.

A rectangular prism has a volume 144 centimeters. The base is a square with a length of 4 cm. What is the height of the prism?
Vitek1552 [10]
The volume is the product of the height and the area of the base.
  V = Bh
The area of the square base is (4 cm)² = 16 cm², so the height can be found from
  144 cm³ = (16 cm²)h
  h = (144 cm³)/(16 cm² = 9 cm

The height of the prism is 9 cm.
