Area of den =8x3 = 24ft²
living room = 7x6 = 42ft²

total = 24+42 = 66ft²

An employer interviews 12 people for four openings at a company. Five of the 12 people are women. All 12 applicants are qualifie

MA_775_DIABLO [31]

Answer:

a) The employer can fill the four positions in 495 ways.

b) The employer can fill the four positions in 210 ways.

Step-by-step explanation:

The order is not important.

For example:

Selecting John, Laura, Mary and Tre'Davious is the same as selecting Laura, John, Mary and Tre'Davious.

So we use the combinations formula to solve this problem.

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.

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

(a) the selection is random

There are 12 people, and 4 are selected. So

$C_{12,4} = \frac{12!}{4!8!} = 495$

(b) exactly two selections are women?

There are 7 men and 5 women. We want to select 2 men and 2 women. So

$C_{7,2}*C_{5,2} = \frac{7!}{2!5!}*\frac{5!}{2!3!} = 210$

What is 22,119 rounded to the nearest hundred?

Ray Of Light [21]

Hello there,

22,119 to the nearest hundred would be 22,100 because 119 is closer to the hundred and not 200.

Hope this helps.

Smallest to largest 0.8 30% 3/5

rjkz [21]

Change everything to the same thing. See like how 30% is a percent you can move the decimal of 0.8 to make it a percent like 80%, then for 3/5 you divide 3 by 5 and you get 0.6 then you can move the decimal to get 60%. So all you have to do now is order the percentages from smallest to largest. Like so 30%, 60%, 80% which then ends up as 30%, 3/5, 0.8.
