An airport shuttle service uses a van that can accommodate a driver and 9 passengers. Past experience has shown that 80% of people who make a reservation actually show up. The probability of any person showing up for the van is independent from whether other people show up or don’t show up. If the shuttle service takes 9 reservations for the 2 p.m. shuttle, what is the probability that exactly 7 people show up? ANSWER (4 decimal places):_______________________ In order...

05 Question (4 points) A video game developer hires two types of workers to develop games: game coders (x1) and game testers (x2). The developer produces games according to the following production function: y = x14x3/4, where y stands for the number of games developed per month, and X1 and x2 stand for, respectively, the number of programmers and testers hired per month. Because both types of workers freelance using their own tools, the video game developer does not require...
