There's a monthly raffle at work for 5 parking spaces out back. There are about 30 people in my office. There's no limit to the amount of tickets you can buy. You can only win once. Otherwise, parking costs about $4 a day, or about $80 a month. Raffle proceeds go to charity. What's the optimal amount to spend on this? [more inside]

Please help me make more meaningful graphs for my boss! Our department runs computer labs on campus, and being the end of the school year we're looking at utilization rates. I can give him: number of users served per hour; number of machines used per hour; and average session time per hour. What he also wants is some sort of utilization, or fill factor graph. But none of us can really figure out what formula to use. [more inside]

On blank graph paper, what is the mathematically proper name for any random line you see on the page? It wouldn't be "coordinate" since that refers to the line's value. It wouldn't be "grid" since that refers to all of the visible lines. It wouldn't be "axis" since there can be only one in each direction. I'd also be cool with the name for all of the lines (as a set) that are parallel to one another. Thanks!

I have created an excel spreadsheet that pulls data from the web, it works great. The only problem is that I can't tell if the data has changed over time. The website that I am pulling from doesn't track changes over time but it would be helpful for me. Is there a way to graph the data over time?

Is there a finance website that can plot historical and current graphs of a stock price in a currency other than that of its local exchange, e.g. the stock price of IBM in USD multiplied by the (moving, not current!) EUR:USD exchange rate? If this is easy to do on Google or Yahoo Finance then I'm obviously missing something!

Math/CS majors: What algorithms are out there to do "approximate reductions for weighted graphs"? This is a term I made up, but basically I have a 200,000 node graph with weighted edges and I want to reduce it so I can see clusters and/or patterns. I know of SUBDUE, but it only works for unweighted graphs.

I'm trying to track down a graph I once saw in a book - pretty sure it was an evolutionary psychology book - that compared the ratio of number of mates/sexual partners with either brain or body size among primates. Humans fell somewhere in the middle, at about 2.5 mates each (i.e. an argument about how "natural" monogamy is to our species.) Any ideas?
