What is the Range of the height of buidings in feet:
8 , 12 , 6 , 8, 12 , 18 , 11, 20 , 8
The range of the height of buildings in feet is 14, as the tallest building is 20 feet and the shortest is 6 feet.
To find the range of the height of buildings, we need to find the difference between the highest and the lowest value.
First, let's arrange the heights in ascending order:
6, 8, 8, 8, 11, 12, 12, 18, 20
Now, we can find the range by subtracting the lowest value (6) from the highest value (20):
Range = 20 - 6 = 14
Therefore, the range of the height of the buildings is 14 feet.
