More Network Examples

Friday in class we started off with mental math, which was quite interesting. We then went on to do some more network examples:

This example shows the number of DIRECT ways to get from one city to another. For example, if you wanted to get from Winnipeg to Brandon, there would be one direct way, but if you were to go from Brandon to Lynn lake, there is no direct route. We then found the number of ways you could get from one city to another goin through one town, and so on. The graphing calculator example shows the number of ways you can get from one town to another going through 2 other towns. An easy way to tell is if you take the original matrix and raise it to the 2nd power, and so on.

We then did another example based on an old provincial exam:

For those of you that are still having trouble with the transition matricies, here's another example for you:

This is question 5 off exercise 6, and it starts off like this:65% of the fitness club members will also use the pool, 78% of the new members will use the pool, 59% of new members will use the fitness room

Using those percentages, you then have to write a matrix showing the expected use of the fitness room and pool. Then in B) you have to show the distrubtion of old and new members. Then in C) multiply the answers in a and b to find out how many members will use each facility after the pool is done.

If you still need help with this, exercise 8 will help with the networks, and excercise 6 will help with the transtional matricies.
