Asociologist 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

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

stop cheating

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
