Answer:

s is not inversely proportional to t

Explanation:

This is an edited response. My first answer was incorrect.

s is not inversely proportional to t. I had responded that they were, based on the fact that as s went up, t went down. But the question was not simply is there an inverse relationship, but are they inversely proportional.

The term proportional means that the relationship between s and t is a constant. That is:

t = s*(1/x)

Let's rewrite that to y*x = k and then check the numbers. See the attached spreadsheet. If the relationship were inversel proportioanl, thaen the product of t*s would be a contant for the series. The third set is different from the first two. The data has an is inverse relationship, but it is NOT proportional.
