A corporation must appoint aâ€‹ president, chief executive officerâ€‹ (CEO), chief operating officerâ€‹ (COO), and chief financi

bija089 [108]

Answer:

A) 715 ways

B) 715 ways

C) (1/715)

Step-by-step explanation:

This is a permutation and combination problem.

Since we want to select a number of people from a larger number of people, we use combination as the order of selection isn't important now.

A) How many different ways can the officers be appointed?

There are 4 officer positions.

There are 13 people in total.

We want to select 4 people from 13

Number of ways to select 4 people from 13 = ¹³C₄ = 715

B) How many different ways can the committee be appointed?

Number of committee members = 4

Total number of people available = 13

Number of ways to select 4 people from 13 = ¹³C₄ = 715

C) What is the probability of randomly selecting the committee members and getting the four youngest of the qualified candidates?

Selecting a group of the youngest candidates is just 1 amongst the total number of ways the 4 committee members can be picked,

Hence, the required probability = (1/715)

Hope this Helps!!!

Use the elimination method to solve the system of equations?<br> 6x+2y=8<br> 12x+y=22

Xelga [282]

The solution is: x=2, y=-2

Step-by-step explanation:

Given equations are:

6x+2y=8 Eqn 1

12x+y=22 Eqn 2

Multiplying Eqn 1 by 2

$2(6x+2y)=2(8)\\12x+4y=16$ Eqn 3

Subtracting Equation 2 from eqn 3

$12x+4y-(12x+y)=16-22\\12x+4y-12x-y=-6\\3y=-6\\Dividing\ both\ sides\ by\ 3\\\frac{3y}{3}=\frac{-6}{3}\\y=-2$

Putting y=-2 in eqn 2

$12x-2=22\\Adding\ 2\ on\ both\ sides\\12x-2+2=22+2\\12x=24\\Dividing\ both\ sides\ by\ 12\\\frac{12x}{12} = \frac{24}{2}\\x=2$

The solution is: x=2, y=-2
