For a game at the carnival you get to roll a ten-sided die, numbered from 1 to 10. If
you roll at least a 3, you win $10. Unfortunately, if you roll anything else, you
lose $15. How much money do you expect to make (or lose) per game?

Aci is desired for the true average stray-load loss μ (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. assume that stray-load loss is normally distributed with σ = 2.3. (round your answers to two decimal places.)
