In how many ways can a committee of four men and four woman be formed from a group of seven men and eleven women?

1 answer:

3 0

Choosing 4 men from seven can be done in 7C4 = 35 ways
(There are 7 to choose from then 6 and 5 and 4 = 7 x 6 x 5 x 4
but we don’t want them in order so we need to divide by 4! = 4 x 3 x 2 x 1)
Similarly choosing 4 women from 11 can be done in 11C4 = 330 ways.

Total number of ways to choose 4 men and 4 women = 35 x 330 = 11550

Which of the following square root of -80

Marta_Voda [28]

You can factor -80 as

$-80 = (-1)\cdot 16 \cdot 5$

So, we have

$\sqrt{-80} = \sqrt{(-1)\cdot 16 \cdot 5}$

The square root of a product is the product of the square roots:

$\sqrt{-80} = \sqrt{(-1)}\sqrt{16}\sqrt{5}$

Since $i^2=-1$ and $4^2=16$ , we have

$\sqrt{-80} = 4i\sqrt{5}$

What is the difference between a relation and a function in mathematics?

Alexandra [31]

A relation are two sets of elements noted as input and output. Within relations, the input and the output have something in common.

A function is also about input and output but in a function, the input has nothing in common with the output.
