Answer:
Range is 18.
Step-by-step explanation:
Range can be calculated by subtracting the smallest value of the data set from the largest value of the data set.
The values are:
13, 17, 18, 15, 12, 21, 10, 6, 8, 11, 3
Largest Value in this data set: 21
Smallest Value in this data set: 3
Range = Largest Value - Smallest Value
Range = 21 - 3
Range = 18

To raise 4x/y to a power, raise the numerator and denominator to the power, and then divide.

Expand (4x)².

Calculates 4 to the power of 2 and gets 16.

Answer:
