The headline in an independent paper that services a large metropolitan area stated that 36 % ( p = 0.36) of houses cost less than $375,000. Sayed read the headline and decided to compute a confidence interval for the proportion of all houses in that area that cost less than $375,000. His 99 % confidence interval was based on a simple random sample of 100 houses from the area, and the limits of the interval where from 0.29 to 0.43 .

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
