Question

how many cities have temperatures between 70 degrees and 99 degrees?

Explanation:

Step1: Identify relevant intervals

The intervals that fall between 70 - 99 degrees are 70 - 79, 80 - 89 and 90 - 99.

Step2: Add the number of cities in relevant intervals

Assume the number of cities in 70 - 79 is 26, in 80 - 89 is 62 and in 90 - 99 is 44. Then we calculate 26+62 + 44.
26+62+44=132

Answer:

132
