loris [4]

Answer:

6.69

How many ways can 6 people be chosen and arranged in straight line if there are 8 people to choose from? a. 48.b. 720.c. 20, 160
Ipatiy [6.2K]

Answer:

<h2>C. <em>20,160</em></h2>

Step-by-step explanation:

This question bothers on permutation since we are to select a some people out of a group of people and then arrange in a straight line. If r object are to be arranged in a straight line when selecting them from n pool of objects. This can be done in nPr number of ways.

nPr = n!/(n-r)!

Selection of 6 people out of 8 people can therefore be done in 8C6 number of ways.

8P6 = 8!/(8-6)!

8P6 = 8!/2!

8P6 = 8*7*6*5*4*3*2!/2!

8P6 = 8*7*6*5*4*3

8P6 = 56*360

8P6 = 20,160

<em>Hence this can be done in 20,160 number of ways</em>

The sum of four consecutive integers is 342. What is the third term in the sequence
Fofino [41]

Answer:

86

Step-by-step explanation:

let  four consecutive integers: n  , n+1  , n+2  , n+3

n  + n+1  + n+2 + n+3 = 342

4n + 6 = 342

4n + 6  - 6  = 342 - 6

4n = 336

divid by : 4

n = 84

but the third term is : n +2   so : 84+2 = 86
