Different groups of 50 graduates of an engineering school were asked the starting annual salary for their first engineering job after graduation, and the
sampling variability was low. If the average salary of one of the groups was
$65,000, which of these is least likely to be the average salary of another of
the groups?
A. $65,000
B. $54,000
C. $67,000
O D. $64,000

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

3100
