The data set consists of information on 4700 ​full-time full-year workers. The highest educational achievement for each worker was either a high school diploma or a​ bachelor's degree. The​ worker's ages ranged from 25 to 45 years. The data set also contained information on the region of the country where the person​ lived, marital​ status, and number of children. For the purposes of these​ exercises, let AHE ​= average hourly earnings​ (in 2005​ dollars) College ​= binary variable​ (1 if​ college, 0 if high​ school) Female ​= binary variable​ (1 if​ female, 0 if​ male) Age ​= age​ (in years) Ntheast ​= binary variable​ (1 if Region​ = Northeast, 0​ otherwise) Midwest ​= binary variable​ (1 if Region​ = Midwest, 0​ otherwise) South ​= binary variable​ (1 if Region​ = South, 0​ otherwise) West ​= binary variable​ (1 if Region​ = West, 0​ otherwise)

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
