MiniMax and Decision Tree Payoff Questions

I have 3 individual questions related to a class lecture that we had on Payoff Alternatives and Regret. These questions should be VERY simple, and probably take less than 2 minutes to answer... so I believe that one (1) credit is reasonable for the quick answers... 1. Is it true that the payoff at the end of a decision ...continues

Rotating bodies and angular momentum : Rolling objects and moment of inertia

A sphere of radius mass M and moment of inertia I rolls down a slope that is inclined at an angle phi to the horizontal. The sphere starts from rest and rolls without slipping a distance L down the slope. Choose coordinates x and theta as shown. a) Write down a relationship between x and theta. (Answer x =R*theta) b) Wri ...continues
