Using the table below, find the average rate of change of population from 1990 to 2000. The population represents f(x) and the year represents x year.

1970 1980 1990 2000
population (million) 2.1
6.4
9.2
10.5
Possible answers
-0.13 million per year
0.13 million per year
7.69 million per year

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

a
