If a population is a sample of the population could be . Answers:
a.) All students at a high school; students at the high school whose ID number ends in "7"
b.) Those with window seats; all passengers on a bus
c.) Baseball players; all athletes
d.) Straight-A students; the entire student body

A. would be the correct answer.

Step-by-step explanation:

If a population is all students at a high school a sample of the population could be students at the high school whose ID number ends in "7".

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.
