## Perpendicular Lines

Why do I need to know about perpendicular lines? To protect you from derailed trains! Watch video to learn more…

SPOILER: I mention details from the movie Super 8.

(This is the first video I created using ShowMe on my iPad.)

## Math for Bank Robbers: Part I

Does crime pay?

A pair of British economists analyzed data from 364 bank heists in the UK to answer that question.

After converting to US Dollars the average heist nets \$31,600. Split between the average 1.6 robbers, each person gets \$19,700. (BTW, the standard deviation is \$83,000. So a lot earned around \$20K and a few earned A LOT more.)  Roughly one-third of all heists end with the robbers earning nothing.  And about 20% end in the capture of the robbers.  (After 4 heists the odds of capture go up to 59%.)

So you might want to rethink a career as a bank robber.  Even if you hit 4 banks a year you’re making less than \$80K and you will probably get caught.  (Which means they would confiscate any earnings you haven’t spent…)

Is it better for US bank robbers?

No, it’s worse. The average heist in the US only nets \$4,330.

The only criminals making money at the banks are the bankers.

## Welcome to Wild Math

My name is Damon Hedman. I teach High School math (mostly Algebra II) at International Polytechnic High School, also know as I-Poly.

Welcome to Wild Math. I plan on discussing why math is important and how it should be taught. This will include discussion of “Wild Math Problems.” These are real life problems or situations where you can apply math.
