Chapter 4.3, Problem 157E
For the following problems, use Newton’s law of cooling.
157. [T] The liquid base of an ice cream has an initial temperature of 210°F before it is placed in a freezer with a constant temperature of 20° F. After 2 hours, the temperature of the ice-cream base has decreased to 170°F. At what time will the ice cream be ready to eat? (Assume 30°F is the optimal eating temperature.)

QUESTION 18 - 1 POINT
Jessie is playing a dice game and bets $9 on her first roll. If a 10, 7, or 4 is rolled, she wins $9. This happens with a probability of . If an 8 or 2 is rolled, she loses her $9. This has a probability of J. If any other number is rolled, she does not win or lose, and the game continues. Find the expected value for Jessie on her first roll.
Round to the nearest cent if necessary. Do not round until the final calculation.
