SOVA2 [1]

Answer:

(a) 56 ways

(b) 6 ways

Step-by-step explanation:

Given:

candidates: 6 mail, 1 female

number to hire : 3

a) In how many different ways can choose new employees?

use the combination formula to choose r to hire out of n candidates

C(n,r) = C(8,3) = 8! / (3! (8-3)! ) = 40320 / (120*6) = 56 ways

b) In how many different ways can choose a single male candidate?

6 ways to choose a male, one way to choose two female, so 6*1 = 6 ways

c) In how many different ways can choose at least one male candidate?

To choose at least 1 male candidate, we subtract the ways to choose no male candidates out of 56.

Since there are only two females, there is no way to choose 3 female candidates.

In other words, there are 56-0 = 56 ways (as in part (a) ) to hire 3 employees with at least one male candidate.

How do I solve this? Please show steps clearly so i can understand, thank you

Lesechka [4]

Answer:

The value of $x=8$ .

Step-by-step explanation:

Given:

$\frac{x+3}{x}-\frac{x+1}{x+4}=\frac{5}{x}$

We need to solve this equation.

Solution:

First combining equation having same denominators we get;

$\frac{x+3}{x}-\frac{5}{x}=\frac{x+1}{x+4}$

Now denominators are common so we will solve the numerators we get;

$\frac{x+3-5}{x}=\frac{x+1}{x+4}\\\\\frac{x-2}{x}=\frac{x+1}{x+4}$

Now by cross multiplication we get;

$(x-2)(x+4)=x(x+1)$

Now Applying distributive property we get;

$x^2+4x-2x-8=x^2+x\\\\x^2+2x-8=x^2+x$

Now Combining the like terms we get;

$x^2+2x-x^2-x=8\\\\x=8$

Hence on solving we get the value of $x=8$ .
