Aparking lot charges $3 to park a car for the first hour and $2 per hour after that. if you use more than one parking space, the second and each subsequent car will be charged 75% of what you pay to park just one car. if you park 3 cars for t hours, which function gives the total parking charge? a. f(t) = 3(3 + 2(t − 1)) b. f(t) = (3 + 2t) + 0.75 ×  2(3 + 2t) c. f(t) = (3 + 2(t − 1)) + 0.75 × 2(3 + 2(t − 1)) d. f(t) = (3 + 2t) + 0.75(3 + 2t) + 0.75 × 0.75(3 + 2t) e. f(t) = (3 + 2(t − 1)) + 0.75(3 + 2(t − 1)) + 0.75 × 0.75(3 + 2(t − 1))

The vice president of programming at nbc is finalizing the prime-time schedule for the fall. she has decided to include a hospital drama but is unsure which of two possibilities to select. she has a pilot called the surgeon and another called critical care. to her make a final decision, a sample of 20 viewers from throughout the united states was asked to watch the two pilots and indicate which show they prefer. the results were that 12 liked the surgeon, 7 liked critical care, and one had no preference. state the decision rule, using the 0.10 significance level. h0: π = 0.50 h1: π ≠ 0.50 1. reject h0 if number of + signs is either < = or > = 2. what is your decision regarding h0? is there a preference for one of the two shows?
