The probability distribution table shows the proportion of people living in the five different regions of a city. there are now 46,700 residents in the city.

how many live in the west region?

probability distribution table question

question 2 options:

467

934

2335

9340

Answer : The number of people that live in the west region are, 9340

Step-by-step explanation :

As we are given that the probability that a person randomly selected lives in the west region is, 0.2

The number of resident in the city = 46700

Let the number of people that live in the west region be, 'x'

So,

x = Number of resident in the city × Probability that a person randomly selected lives in the west region

Therefore, the number of people that live in the west region are, 9340

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
