2w+2⋅(3w)≥112

2w+2⋅(3w)≤112

2w+2⋅(3w)<112

2w+2⋅(3w)>112

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?
