Answer:
7
Step-by-step explanation:
3^2 = 9
(-4)^2 = 16
16-9= 7
11
first, sort the numbers from lowest to highest.
5,5,6,7,8,9,10,*10,12*,14,15,17,18,18,18,20
the median is the number in the middle of the data
average if you need to (10+12 and divide by 2)
10' 11''
131 / 12 = 10.1666...
10 * 12 = 120
131 - 120 = 11
12 represents the feet and the remainder, 11, is the inches.
