As we all know, because of market psychology when stocks increase in price on one day, they tend to decrease in price the next day. A payoff matrix shows the pertinent percents.

Now here's the payoff matrix.

If today the stock price increases, then the likelihood it will increase tomorrow is 0.2 and the likelihood it will decrease tomorrow is 0.8.

If today the stock price decreases, then the likelihood it will increase tomorrow is 0.6 and the likelihood it will decrease tomorrow is 0.4.

So the question is, in the long run, what fraction of the time will the stock increase in price?

Im not referring to approximations. Anyone can guess a number and methodologically modify it for accuracy. Im talking a real algorithm or equation of what have you that was used for sole purpose of determining the value of e, not validating it or verifying it. How was the number originally computed? What mathematical background and conceptual basis was necessary for this technique?

In a remote country, the monetary unit is called UNI. They only
have bills of 20 UNI and coins of 3 UNI.

You want to buy a toy at a store, but the clerk can't give
you the change back (so you have to pay the exact price).

Show that it is always possible to buy a toy as long as its price
is large enough...

A man (or a woman!) wants to buy an engagement ring. S/he has a choice of 4 metals (gold, silver, platinum, titanium), 3 stones (diamond, emerald, ruby) and 3 cuts of stone (Tiffany, square and round).

Assuming they must choose one specific type of metal, one type of stone and one cut, how many different ring combinations do they have to choose from?

1. Solve the equation, noting any double roots.
x^3+9x=6x^2


2. Solve by factoring. 6x^3+3x^2-9x=0
Why does it equal to 0?

I've been puzzled by the idea of building efficient roads based on the following criteria:
1) Minimize total length of roads built (each mile costs 1 point)
2) Minimize distance required to travel between any two cities specified (each mile costs one point, with total distance score = sum of roads required to travel between all distinct pairs of cities)

Notes:
Ignore existing roads in this problem. You are building roads from scratch.

Ignore topography. You can build roads anywhere.

Roads do not need to connect two cities directly... you can have "ghost nodes" between cities that roads connect through, if that makes your system more efficient.

Where would you put the roads to minimize total points? What technique did you use to determine your solution?

No, I'm not in college taking a final exam. I'm just personally curious about this problem.
