Answer:
A. 4
Step-by-step explanation:
First rearrange the temperatures from low to high
60, 65, 68, 69, 69, 70, 70, 70, 71, 71, 73, 74, 75, 77
There are 14 data,
Q1 = 4th data = 69
Q3 = 11th data = 73
Interquartile range = Q3 - Q1 = 73 - 69 = 4
Adding all of the areas together:
5 x 6 = 30
4 x 6 = 24
3 x 6 = 18
4^2 + 3^2 = 16 + 9 = 25(square root) = 5
" " = 5
30 + 24 + 18 + 5 + 5 = 82 ft^2
Step-by-step explanation:
