[Math4u] Re: sorry forgot to attach data //I really need help ...

This is interesting. Apparently these are the moons of Saturn. I
imagine that these columns of data are related to each other by some
exponential.

You have 6 columns. Take the log of the data in each column. If you
graph the logs for the left 3 columns, there should be a linear
relationship between them. The slopes will tell you to what power
they are related to each other.

There will be a rough correlation between the 4th and 5th columns.
This will not be exact because the density of the moons may vary.
Columns 5 and 6 should be directly proportional (a ratio but not a
fraction) to each other.

Regards,

Brian
