Answer:
You start the shelf 4 ft. 9 in. from the wall.
Step-by-step explanation:
The game plan is to take the length of the shelf away from the length of the wall, and then divide the remaining part into two equal pieces.
13 ft.
- 3 ft. 6 in.
12 ft 12 in,
- 3ft 6 in
9 ft 6 in.
9 ft. 6 inches divided by 2 equals 4.5 ft, 3 in.
.5 ft * 12 inches = 6 inches
You start the shelf 4 ft. 9 in. from the wall.
4 congruent sides

D is answer
8, 11, 12, 13, 16, 42
Add together and divide by 6 to get the mean.
102/6 = 17
Find the middle of the data for the median.
(12 + 13)/2 = 12.5
The mean is 17, the median is 12.5, and the mean is more affected by the outlier. 17 (the mean) is not a good measure of center.
