Just answer soon. will mark !
a survey of 1,000 men and women asked, "do you earn over $55,000 per year? " the table below shows the responses for males and females:
male female total
income over $55,000 475 375 850
income below $55,000 75 75 150
total 550 450 1,000
based on these data, are "being male" and "earning over $55,000" independent events?
no, p(being male | the person earns over $55,000) ≠ p(being male)
no, p(being male | the person earns over $55,000) = p(being male)
yes, p(being male | the person earns over $55,000) = p(being male)
yes, p(being male | the person earns over $55,000) ≠ p(being male)

answer: ouch. thats difficult

step-by-step explanation:

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

if i put something wrong your not gonna like it so rather not say nothing.
