Acertain committee consists of 17 people. from the committee, a president, a vice-president, a secretary, and a treasurer are to be chosen. in how many ways can these 4 offices be filled? assume that a committee member can hold at most one of these offices.

57120

Step-by-step explanation:

Total number of people in a committee = 17

We need to select a president, a vice-president, a secretary, and a treasurer from the committee .

We need to find the number of ways in which these four positions can be filled .

Also, assume that a committee member can hold at most one of these offices.

For post of president , we can choose from 17 people

For post of vice - president , we are left with 16 choices only as one person has already been selected for post of president .

For post of a secretary  , we are left with 15 choices only as two persons have already been selected for post of president and vice - president .

For post of a treasurer  , we are left with 14 choices only as three persons have already been selected for post of president , vice - president and treasurer .

So, number of ways in which these four positions can be filled  =

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
