Factoring, I guess, but it really depends on the type of polynomial question. Can you give a sample?

I think you have to make a histogram. Make the x axis be the values (make it in ranges though, like $340-$350, $350-$360, etc) and then put the number of people who thought it would be in that range  on the y axis and make a bar graph. this is called a histogram. you should get a bell curve around the actual value i think.\n\nother than this, i cant think of another way you could do it, but the way that you said is wrong (most likely).

this really only works when its done verbally...when people are looking at the numbers, its much easier to realize that the answer is 4100 instead of 5000, pretty neat one isnt it

Look at them carefully, find out the diff between each number and it should be obvious.\n\nEquations?

You would need to perform the calculations yourself.  But, here is a useful website that will help you understand the inputs you need for making those calculations:\nhttp://pages.stern.nyu.edu/~adamodar/

I do not know a preprogrammed utility to do this, but can point you in the direction that you might need to go.  See the reference below for the math and an on-line converter:

You simply type: \n=rand(25,25) and then enter.

hmm use a calculator...i am sure a ti-83 can show you how to do it, and/or this problem is impossible..but i am sure you can do it..or am i...man now you confused me you have this in the tennis section???

I think you just take the numbers and plug them in where the letters are and find your result.  Ie.  every time you see an a in the question, write -2 instead and then work it out...
