The following table shows the data collected from a random sample of 100 middle school students on the number of hours they do h
ousehold chores every week: Weekly Duration of Household Chores Time (in hours) 0–1 2–3 4–5 6–7 Number of Students 32 64 3 1 There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to do household chores for at least two hours every week? 480 960 1,020 1,440
The area is 120/(1/4) or 120 x 4 or 480 square inches the width is 6/(1/2) or 6 x 2 or 12 inches to find the length, divide the area by the width 480/12= 40 40 inches Hope this helps :)
