2. John and Morgan purchase a foreclosed property for $50,000 and had to spend an additional $27,000 fixing up the property. They feel that they can resell the property for $120,000 with
probability of 0.15, $100,000 with probability of 0.45, $80,000 with probability of 0.25, and
$60,000 with probability 0.15. Compute and interpret the expected profit for reselling the
property.

Ateacher attaches a ball to a meter long string and whirls it around in a horizontal circle at constant speed. the teacher explains that the string is what makes the ball go in a circle. why is the string necessary? a) the string is needed to apply a torque to the ball. b) the string is needed to push on the ball to get it up to speed. c) circle motion requires an inertia which is provided by the string. d) circle motion requires a force to give it a centripetal acceleratio
