Make Sense? During the winter, you program your home thermostat so that at midnight, the temperature is 55 °. This temperature is maintained until 6 A.M. Then the house begins to warm up so that by 9 A.M. the temperature is 65 °. At 6 P.M. the house begins to cool. By 9 P.M., the temperature is again 55 °. In Exercises 137–140, determine whether each statement makes sense or does not make sense, and explain your reasoning. If the statement makes sense, graph the new function on the domain [0, 24]. If the statement does not make sense, correct the function in the statement and graph the corrected function on the domain [0, 24]. I decided to change the heating schedule to start one hour earlier than before, so I reprogrammed the thermostat to y = f ( t – 1).

Amy and Samiha have a hat that contains two playing cards, one ace and one king. They are playing a game where they randomly pick a card out of the hat four times, with replacement.
Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater.
The sample space of possible outcomes is listed below. A represents an ace, and K represents a king. Who is correct?
