Homework Answers
an interval from 7 to 11 would have 7 as the lower limit and 11 as the upper limit.
Sum the upper and lower limit. In the example, 7+11 =18
Divide the sum of the upper and lower limits by 2. The result is the midpoint of the interval. In the example, 18 divided by 2 yields 9 as the midpoint between 4 and 8.
Midpoint is 9
