A sociologist recorded the estimated life expectancies of women born in center city. Use data from women born in 1710 and 2000 to create linear model that predicts the life expectancy, in years(y) of a female born in a given year (x)

Step-by-step explanation:

I think the below is your full questions:

A sociologist recorded the estimated life expectancies of women born in Center City. Use the data from women born in 1970 and 2000 to create a linear model that predicts the life expectancy, in years, (y) of a female born in a given year (x). . . Year Born Life Expectancy (years). 1960 66.1. 1970 67.6. 1980 70.1. 1990 71.9. 2000 74.0. 2010 75.9. Which equation represents this linear model?

y = 0.213x – 352.0

y = 0.213x – 358.4

y = 4.695x – 9181.6

y = 4.695x – 9322.4

Here is my

Plug in the values of x into the equation for a double check in each option:

Let's try 1980. we have:

a) y = 0.213 (1980) - 352.0

<=> y = 69.74

closest to 70.1 while the other options do not satisfy the condition.

b)  y = 0.213 (1980) - 358.4  = 63.43

c) y = 4.695(1980) – 9181.6  = 114.5

d)  y = 4.695(1980)  - 9322.4  = -26.3

So a is the correct answer

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

show us the graphs dude
