How to make up an equation

If I have 66 accidents in 2005 and 47 in 2006, how do I find the estimated accidents for 2007 and what equation would I give?

Well, that's very little information - but a hint could be %

jxharmon · 2007-01-29 13:15:16

What more info would be helpful? and how would I put % into an equation?

This is a little more of an explanation of what I need to do. Any help would be great.

Take the real-life situation you described (2005 & 2006 accidents) and create an equation or inequality that could be used for analysis, prediction, or decision making. Then, draw a graph to depict the variables in your situation. Use your graph and what you know about linear inequalities to discuss the significance of your findings

take 47 from 66 and that should be an estimate

Ok...that really confuses me. That means there would be 19 accidents estimated for 2007????

I'd say to use that 19 as a "rate of decrease" statistic, and so take 19 away from 47 to guess how many accidents there would be in 2007. So, that method would give 28 accidents. That obviously doesn't work properly though, because if you continued it then you'd get negative amounts of accidents.

So maybe you need to work out the percentage decrease and use that. However, if you did that then you'd get fractional amounts of accidents, so that wouldn't make sense either. There's no good way of estimating a figure, simply because there isn't enough data to go on. But from what's given, I'd go with the percentage method.

That would give you a figure of 33 accidents happening. But that is only a very rough guess. It's a very complex thing to try to work out, and there are probably tons of factors we haven't even thought of, let alone considered.

Is it Linear ? Impossible to tell from only two statist
