Answer:

d = 17

Step-by-step explanation:

d = √ (9 − 1) 2 + (15− 0)^2

d = √ (8) ^2 + (15) ^2

d = √ 64 + 225

d = √289

d = 17

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

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

Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warrant

pashok25 [27]

Answer:

The fixed amount Geet earns for each television is $60.

Step-by-step explanation:

Given:

Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warranty.

If Geet sells 17 televisions with extended warranties, he earns $ 1,530.

Now, to find the fixed amount Geet earns for each television.

Let the cost of fixed amount be $x$ .

Number of television = 17.

He earns total = $1,530.

He earns additional amount = $30.

Now, to get the fixed amount we put an equation:

$17(x+30)=1530$

$17x+510=1530$

Subtracting both sides by 510 we get:

$17x=1020$

Dividing both sides by 17 we get:

$x=60.$

Therefore, the fixed amount Geet earns for each television is $60.
