1. Ms. Soloway wanted to know about students’ enrichment preferences at Leadership Prep Ocean Hill. Ms. Soloway randomly sampled LPOH students by asking every 5th student at arrival what their favorite enrichment was. The results of Ms. Soloway’s survey are shown in the table below: Out of 500 total LPOH students, about how many would you expect to prefer music? Explain how you used the information in the survey to make the prediction.

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.
