LOL...go get some rest and thanks tons!!!
I went to smarthinking.com to ask a tutor for the equation and unfortunately
neither the algebra or statistics tutors could help me. You ought to apply
there for a job! But I think their site is outsourced and you might need to
speak another language, or 3:)
This really helps tons!
Thanks again:)

Well, I emailed my instructor and let him know that I would be doing that
assignment tomorrow morning. When I get back to that page it kicks up an
error message on the ones that are wrong. I'll post the results after I get
that done. I can't believe someone is paying tutors that can't tute!...lol
Anyways, I really do appreciate the help.
I took first year math last term, but it didn't cover anything like what was
needed here. Over summer I need to practice on math because this degree
requires that I go all the way to calculus...yikes!

I never took Geometry and I only know up to Algebra (forgot tons), so by
logic (LOL), I would think
those 6 areas are 6 decades of that month's average rainfall. Then you take
the highest average and make that your emergency flood possibility.
