The campus bookstore sells a campus mug for $1010. When you buy a second campus mug, however, its price is only $66. How does this relate to marginal utility? Part 2 A. As more is consumed, the marginal utility increases so consumers are willing to purchase more at higher prices. B. Increases in total utility from the consumption of campus mugs become larger as more is consumed so consumers will pay more. C. Since marginal utility falls as additional units of the good are consumed, consumers are only willing to purchase more as the price falls. D. The cost of a campus mug becomes cheaper as more are consumed.

Binomial Distribution A business phone line in an order processing center is setup to receive both voice calls and fax messages. Suppose 30% of the incoming calls are fax messages, consider a sample of 10 incoming calls during a 30-minute period. (It is assumed that the processing center gets ~10 calls during a typical 30-minute period.) 1. What is the probability that exactly 6 calls involve fax messages? 2. What is the probability that less than 1 call involve fax message? 3. What is the probability that at least 1 call involve fax message? 4. What is the expected number of fax messages during a 5-hour period? [Hint: 5-hour means 300 minutes.] 5. What is the standard deviation of number of fax messages received during a 30-minute period? 6. What is the probability that the number of calls among 10 calls received in a 30-minute period involving fax transmissions exceeds the expected number by more than 2 standard deviation? Write the complete solution in the form of an equation, but do not need to calculate.

Prob.1. (pts) The root-locus plot of KG(s)H(s) = K \frac{(s+3-jl)(s+3+jl)}{s(s+3)(s+2)} and the desired region (PO ?5% (? ? 0.7) and t ? 4 sec, are given below. a. (pts) Label the gain K (such as K?, K?, ..., etc.) at each point where the root- locus intersects the borders of the desired region but do not calculate the gai K at these points. Find the range of the gain K in terms of K?, K?, ... such that all characteristic roots (closed-loop poles) lie inside the desired region.

Given the descriptions below, draw the corresponding ER diagrams and also use Data Definition Language (DDL) to convert them into their relational schema: a. A football player plays in a team managed by a coach. The football player is uniquely identified by his name and date of birth. The player also contains information about their nationality. A team is uniquely identified by the team ID. The team also contains information about the team name. The relationship between a football player and his team contains information about the player's contract start date and contract end date. The coach is uniquely identified by their name and date of birth. The coach also contains information about their nationality. A football player can play for at most one team, and one team can have multiple players. The team is managed by exactly one coach and each coach manages exactly one team. b. A musician produces an album and the album contains songs. A musician is uniquely identified by their stage name. The musician also contains information about their genre. An album is uniquely identified by the album number and the album title. The album also contains information about the release date and the number of songs. A song is uniquely identified by the song name, the album number and the album title. The song also contains information about the duration of the song. A musician can produce multiple albums, and an album can be produced by multiple musicians. Also, the album can contain multiple songs.

A.2 Consider the Hamiltonian for a rigid rotor $H = \alpha L^2$, where $\alpha$ is a number. Show that the expectation values of the total angular momentum $L^2$ are conserved quantities. Are expectation values of $L_z$ conserved quantities? Why does $L^2$ and $L_z$ form a complete set of commuting observables (CSCO). Why does $L^2$ not form a CSCO? Why does $L_z$ not form a CSCO? A.3 Using the properties of the ladder operators $a$ and $a^\dagger$, show that $[a, f(a^\dagger)] = \frac{\partial}{\partial a^\dagger}f(a^\dagger)$ where $f(a^\dagger)$ is an arbitrary function of the lowering operator.
