Answer:
Some of the 50 students should have been assigned to a control group that used the in-person course
Step-by-step explanation:
Given:
Cheshire Road Shelby Road
Plot 1 40 yards 48 yards
Plot 3 x 56 yards
To solve for x, we get the ratio and proportion of both plots.
40/48 = x/56
Do cross multiplication.
40 * 56 = 48 * x
2,240 = 48x
2,240/48 = 48x/48
46.67 = x
Plot 3 of Chesire Road measures 46.67 or 46 2/3 yards. Choice A.
