100 150 200 300 400
determineif the relationship is proportional

Answer 1

To determine if the relationship is proportional, we need to check if the ratios of corresponding values are equal.

Let's calculate the ratios for each pair of corresponding values:

30 / 20 = 1.5
40 / 30 = 1.3333...
60 / 40 = 1.5
80 / 60 = 1.3333...
150 / 100 = 1.5
200 / 150 = 1.3333...
300 / 200 = 1.5
400 / 300 = 1.3333...

Since all the ratios are approximately equal to 1.5 or 1.3333..., we can conclude that the relationship is proportional.
