Identify the interval that is not equal to the other three 15-19 30-34 40-45 45-49

Answer 1

Answer:

45-40

Step-by-step explanation:

The first interval is 15-19.

The width of this interval is: 19-15=4

The second interval is 30-34.

The width of this interval is: 34-30=4

The third interval is 40-45.

The width of this interval is: 45-40=5

The fourth interval is 45-49.

The width of this interval is: 49-45=4

Therefore the interval that is not equal to the other three is 45-40
