I have been using an old version of MathCad on my Mac for some time. It runs under OS 9. I am planning an upgrade to a newer version of OS X that does not allow booting OS 9, and MathCad apparently no longer supports Mac. I would like to find a math program for the Max at a reasonable price (about $100). Any suggestions?

Here's a question that was posted before in a different section, but I began to think about . . .

The median number of lifetime female sexual partners for men was seven; the median number of male partners for women was four.

from:

http://www.msnbc.msn.com/id/19374216/

How is this possible? How can men have a net average number of female partners greater than that of women given that the initial ratio of male/female is 1:1?

If two light sources are 20 feet apart and their intensities are 30 and 20 respectively, at what point between them will the sum of their illuminations be a minimum?

This is about inequalities. I solved it but I don't know which one is the right answer. The question is:
-8w+4>or equal to12

I got w= -1 but there's two answer options that are similar.

a.) w I w b.) wI w>or equal to -1

I'm thinking that the answer is b (doesn't it have to be opposite?), but I'm not sure. Can you tell me which one is the right answer and why?? Thanks.
