Problem 1 Answer: x = 2/3y+8
Show Work:
Step 1: Add 2y to both sides.
3x−2y+2y=24+2y
3x=2y+24
Step 2: Divide both sides by 3.
3x/3 = 2y+24/3
x = 2/3y+8
Problem 2 Answer: x=−2y+48
Show Work:
Add -2y to both sides.
x+2y+−2y=48+−2y
x=−2y+48
The mean distance for a group is the sum of individual numbers over the number of data. The mean distance of Group A is (1+1.5+3+3.2+2.8+1.5+1.8+2.5+2.2)/9=2.17 The mean distance of Group B is (<span>2+2.5+3.2+3+1.8+2.4+3+1.5+1.8)/9=2.36. Therefore, the mean is greater for group B than group A, but not doubling.</span>
