25 people apply for a job, 15 men and 10 women. they will hire 10 people, with 40% of them women. how many different staff selec

luda_lava [24]

So if they'll hire 40% women, and they're hiring 10 people, this means that they'll hire 4 women. And the rest of the people are all men, or 6 of them.

So basically, you can think of this like a tree, taking the men's side first, with 15 possible hires in the beginning, and then 14 more stemming off of that, and then 13 more stemming of those, etc.

So basically it would be:

15 * 14 * 13 * 12 * 11 * 10

Because there are four spots for men, and there were 15 men, and after every hire, there will be one less applicant, because there would've been one hire instead.

So;

15 * 14 * 13 * 12 * 11 * 10 = 3603600

And then women just do the same thing.

10 * 9 * 8 * 7 = 5040

Then just multiply those together as well.

18162144000 is your final answer.

1 meter of ribbon costs $3<br> how much do you pay for 2 3/4 <br> If correct I will brainest u

defon

Answer:

You pay $8 $\frac{1}{4}$ for 2 $\frac{3}{4}$ meters of ribbon

Step-by-step explanation:

Let us solve the question

∵ 1 meter of ribbon costs $3

∵ We need to find the cost of 2 $\frac{3}{4}$ meters

→ Separate the length of the ribbon to a whole number and a fraction

∵ The length of the ribbon = 2 m + $\frac{3}{4}$ m

→ Multiply each part by the cost of 1 meter

∵ The cost of 1 meter = 3 dollars

∴ The cost of the ribbon = 3 × 2 + 3 × $\frac{3}{4}$

∴ The cost of the ribbon = 6 + $\frac{9}{4}$ dollars

→ Change the improper fraction $\frac{9}{4}$ to a mixed number

∵ 9 ÷ 4 = 2 $\frac{1}{4}$

∴ The cost of the ribbon = 6 + 2 + $\frac{1}{4}$

∴ The cost of the ribbon = 8 + $\frac{1}{4}$

∴ The cost of the ribbon = 8 $\frac{1}{4}$ dollars

∴ You pay $8 $\frac{1}{4}$ for 2 $\frac{3}{4}$ meters of ribbon
