A president, treasurer, and secretary, all di erent, are to be chosen from a club consisting of 12 people (whose names are I, J,

Ierofanga [76]

Answer:

There are 220 choices

Step-by-step explanation:

Given

$People = 12$

$Selection =3$ (President, Treasurer and Secretary)

Required

Determine number of selection (if no restriction)

This is calculated using the following combination formula:

$^nC_r = \frac{n!}{(n - r)!r!}$

Where

$n = 12$

$r= 3$

So, we have:

$^nC_r = \frac{n!}{(n - r)!r!}$

$^{12}C_3 = \frac{12!}{(12 - 3)!3!}$

$^{12}C_3 = \frac{12!}{9!3!}$

$^{12}C_3 = \frac{12*11*10*9!}{9!3!}$

$^{12}C_3 = \frac{12*11*10}{3!}$

$^{12}C_3 = \frac{12*11*10}{3*2*1}$

$^{12}C_3 = \frac{12*11*10}{6}$

$^{12}C_3 = 2*11*10$

$^{12}C_3 = 220\ ways$

<em>There are 220 choices</em>

What is the solution to the linear equation 4b + 6 = 2 - b+ 4

inessss [21]

Final Answer: $b = 0$

Steps/Reasons/Explanation:

Question: What is the solution to the linear equation $4b + 6 = 2 - b + 4$ ?

<u>Step 1</u>: Simplify $2 - b + 4$ to $6 - b$ .

$4b + 6 = 6 - b$

<u>Step 2</u>: Cancel $6$ on both sides.

$4b = -b$

<u>Step 3</u>: Subtract $-b$ from both sides.

$4b + b = 0$

<u>Step 4</u>: Simplify $4b + b$ to $5b$ .

$5b = 0$

<u>Step 5</u>: Divide both sides by $5$ .

$b = 0$
