Assignment Questions Let $X$ be a random variable that gives the number of minutes after the instructed time that a person chosen at random shows up. (So for example, if the chosen person was told to show up at 11, and they show up at 10:30, then $X = -30$.) We'll assume at first that the probability density function (PDF) $f(x)$ is the same for everyone. Specifically, $f(x) = \frac{1}{120}e^{-\frac{x}{60}}$ Let's say that a person must be at the gate by noon in order to get on the plane. Anyone arriving after noon misses the plane; anyone arriving before noon makes it on. In this assignment, we'll investigate the time that the airlines should tell their customers to arrive at the gate. Question 2 Suppose the airline tells passengers to be at the gate at 11:00. What is the probability that a person will make it to the gate before noon? Extrapolating from this, what percentage of people do you expect to actually make it on the flight?

What is the torque $\tau_D$ about axis D due to $\vec{F}$? (D is the point located at a distance $d$ from the origin and making an angle $\phi$ with the x axis.) Express the torque about axis D in terms of F, $\theta$, $\phi$, $\pi$, and/or other given coordinate data. $\tau_D = Fd \sin(\phi - \theta)$

Three tables listed below show random variables and their probabilities. However, only one of these is actually a probability distribution. A B C x P(x) x P(x) x P(x) 25 0.4 25 0.4 25 0.4 50 0.1 50 0.1 50 0.1 75 0.3 75 0.3 75 0.3 100 0.4 100 0.2 100 0.6 a. Which of the above tables is a probability distribution? B b. Using the correct probability distribution, find the probability that x is: 1. Exactly 25 = 2. No more than 50 = 3. More than 25 =

Rucker Truck Line (RTL) is evaluating whether the fleet of trucks it owns should be replaced. If the trucks are replaced, current operating revenues and expenses will not change, except for depreciation expenses. Annual depreciation will increase from $150,000 to $175,000. Based on this information, how will the change in depreciation expense affect the incremental operating cash flows RTL when making its capital budgeting decision about replacing the trucks? RTL's marginal tax rate is 40 percent. a. After-tax operating cash flows will increase by $15,000. b. After-tax operating cash flows will increase by $10,000. c. After-tax operating cash flows will decrease by $25,000. d. After-tax operating cash flows will decrease by $10,000. e. Because depreciation is a non-cash expense, operating cash flows should not change
