on the board, your teacher shows an example of finding the range. one of the numbers is erased, leaving what is shown. which of the following could not be true? 18 30 26 12 22 range = 18 the missing number is 11. the missing number is 20. the missing number is 25. the missing number is 30.

Answer

Explanation:

Step1: Recall range formula

Range = Max - Min

Step2: Analyze given numbers

Given numbers are 12, 18, 22, 26, 30. Current min = 12, current max = 30, current range = 30 - 12=18.

Step3: Check each option

If missing number is 11, new min = 11, new range = 30 - 11 = 19≠18.
If missing number is 20, range remains 30 - 12 = 18.
If missing number is 25, range remains 30 - 12 = 18.
If missing number is 30, range remains 30 - 12 = 18.

Answer:

The missing number is 11.
