Median Sale Price The median sale price p (in thousands of dollars) of an existing one-family home in the United States from 2002 through 2014 (see figure) can be approximated by the model p t = 0.757 t 2 + 20.80 t + 127.2 , 2 ≤ t ≤ 6 3.879 t 2 + 82.50 t + 605.8 , 7 ≤ t ≤ 11 − 4.171 t 2 + 124.34 t − 714.2 , 12 ≤ t ≤ 14 where t represents the year, with t = 2 corresponding to 2002 . Use this model to find the median sale price of an existing one-family home in each year from 2002 through 2014 .

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?
Consider the exponential function f(x) = 12x. Complete the sentences about the key features of the graph.
The domain is all real numbers.
The range is y> 0.
