Ike’s Bikes is a major manufacturer of bicycles. Currently, the company produces bikes using only one factory. However, it is considering expanding production to two or even three factories. The following table shows the company’s short-run average total cost (SRATC) each month for various levels of production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.)

Average total cost (dollars per bike)

Suppose Ike’s Bikes is currently producing 25 bikes per month in its only factory. Its short-run average total cost is

per bike.

Suppose Ike’s Bikes is expecting to produce 25 bikes per month for several years. In this case, in the long run, it would choose to produce bikes using   .

On the following graph, plot the three SRATC curves for Ike’s Bikes from the previous table. Specifically, use the green points (triangle symbol) to plot its SRATC curve if it operates one factory (SRATC1SRATC1); use the purple points (diamond symbol) to plot its SRATC curve if it operates two factories (SRATC2SRATC2); and use the orange points (square symbol) to plot its SRATC curve if it operates three factories (SRATC3SRATC3). Finally, plot the long-run average total cost (LRATC) curve for Ike’s Bikes using the blue points (circle symbol).

Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

Original question:

d) Use metacharacters and the ls -lL command (with lower and upper case L) to list all filenames under the datafiles directory that contain a dot '.' with the letter 'f' or 'u' anywhere after the dot.

e) Use metacharacters and a single ls -lL command (with lower and upper case L) to listall file names that contain a dot '.' followed by a lower case letter, then end with the letter 't' or 'r' as the second from last character. And these files should be from your current directory as well as any directory under the current directory that contains the letters "data".
For example: data1/a.pqrs would be a match, but dabta.Dtu and datafiles/.softdo not match.
Hint: use two command arguments, one for the current directory, and one for directories the contain 'data'.

1. A publisher faces the following demand schedule for the next novel from one of its popular authors:

The author is paid $2 million to write the book,

Price 100 90 80 70 60 50 40 30 20 10 0

QD(1000s) 0 100 200 300 400 500 600 700 800 900 1000

and the marginal cost of publishing the book is a constant $10 per book.

a. Compute the total revenue, total cost, and profit at each quantity. What quantity would a profit-maximizing publisher choose? What price would it charge?

The total revenue at each level of production is given by the demand schedule above, using T R = P Q. The total cost is the constant fixed costs of $2 million plus the variable cost of ($10)Q. For convenience, the units of revenue, cost, and profit are given in millions. In the table below, we combine these equations with the calculation of marginal revenue. It turns out that the profit-maximizing level of output is 500,000 units, corresponding to a price of $50.

b. Compute marginal revenue. (Recall that MR = ∆T R/∆Q). How does marginal revenue compare to the price? Explain.

QD(1000s) 0 100 200 300 400 500 600 700 800 900 1000

TR ($ millions) 0 9 16 21 24 25 24 21 16 9 0

TC ($ millions) 2 3 4 5 6 7 8 9 10 11 12

Profit ($ millions) -2 6 12 16 18 18 16 12 6 -2 -12

Marginal Revenue ($) 90 70 50 30 10 -10 -30 -50 -70 -90

Marginal Cost ($) 10 10 10 10 10 10 10 10 10 10

c. Graph the marginal-revenue, marginal-cost, and demand curves. At what quantity do the marginal-revenue and marginal-cost curves cross? what does this signify?

The relevant information is given in the table above. In the table, we can see that marginal cost and marginal revenue are equal at Q = 50. That is MR(50) = MC(50) = 10. Not coincidentally, this is also the profit-maximizing level of output that we found earlier.

d. In your graph, shade in the deadweight loss. Explain in words what this means.

The social surplus maximizing level of output would set the price equal to marginal cost. In that case, P = 10 and then turning to the demand schedule this corresponds to output of Q(10) = 900, 000. The deadweight loss is the surplus that is lost because we do not makes the units from 500,000 to 900,000. In this case, the deadweight loss if represented with a triangle with base 900, 000− 500, 000 = 400, 000 and the height of 50 − 10 = 40. The area of this triangle is 0.5(400000)(40) = 2 million

e. If the author were paid $3 million instead of $2 million to write the book, how would this affect the publisher’s decision regarding what price to charge? Explain.

Recall that there are two questions for the firm — how much to produce, and how whether to stay in business. The first question — how much to produce — is based on comparing marginal costs and benefits (e.g. should I go from 3 to 4? From 4 to 5, and etc.). By definition, marginal costs are variable costs i.e. they are related to how much output is chosen. The increase in the fee to the author is a type of fixed cost. In the current exercise, the fee paid to the author has no affect on the market demand schedule or on the production costs of the book. Thus, there is no affect of the author’s fee on any of the MARGINAL factors in our exercise. The publisher’s profit will go down, but otherwise there is no effect on what choices it will want to make.

3. Below is the number of texts per day for a random sample of students from last semester. (Population normal enough.)

a. Create the 95% confidence interval for both sets of data. Is there evidence that the population means are different? Under 19 years old: 250, 15, 200, 10, 15, 50, 20, 150, 63, 15, 7, 20, 35, 4, 20 At least 19 years old: 100, 20, 40, 5, 30, 100, 100, 65, 5, 25, 20, 50, 10, 10

b. How many more people at least 19 years old would you need to sample to be within 10 texts of the true mean?

Three identical units of merchandise were purchased during July, as follows:

Assume one unit sells on July 28 for $40.

Determine the gross profit, cost of goods sold, and ending inventory on July 31 using (a) first-in, first-out, (b) last-in, first-out, and (c) average cost flow methods.

Problem 9-16

One unit of A is composed of two units of B and three units of C. Each B is composed of one unit of F. C is made of one unit of D, one unit of E, and two units of F. Items A, B, C, and D have 15, 50, 45, and 25 units of on-hand inventory, respectively. Items A, B, and C use lot-for-lot (L4L) as their lot-sizing technique, while D, E, and F require multiples of 45, 100, and 100, respectively, to be purchased. B has scheduled receipts of 30 units in Period 1. No other scheduled receipts exist. Lead times are one period for Items A, B, and D, and two periods for Items C, E, and F. Gross requirements for A are 15 units in Period 1, 15 units in Period 2, 60 units in Period 6, and 50 units in Period 8.

You will design and implement two classes to support a client program, RockPaperScissorsGame.java, to simulate Rock-Paper-Scissors game.

Read and understand the client program to find out the requirements for the HandShape and Player classes.

The rules of the Rock-Paper-Scissors game are:

    Scissors✌️ beats Paper✋ that beats Rock✊ that beats Scissors✌️

Additionally, to simplify the game logic (and complexify a little bit the HandSahpe class) , two players cannot show the same hand shape.

The followings are some sample runs:

                HandShape handShape = new HandShape();
                
                Player player1 = new Player("Alice");
                Player player2 = new Player("Bob");

                System.out.println(player1.getName() + " shows " + handShapeName[player1.showHand(handShape)]);
                System.out.println(player2.getName() + " shows " + handShapeName[player2.showHand(handShape)]);
