There was an old man with a beard

             who said, “It is just as I feared.

             Two owls and a hen,

             Four larks and a wren

             Have all built their nests in my beard”

                                                       Edgar Lear

1. A bird is chosen at random from the beard. What is the probability that it is a wren?
2. Each bird has a little tag with a letter on it, O for owl, H for hen, L for lark, and W for wren. One morning the birds are called out from the beard at random and lined up in a row from the left to the right. What is the probability that their tags are spell out WOLHOLLL?
3. How many teams of 4 birds can be chosen from the beard dwellers if each team must include at least 1 lark?
4. At least 2 larks?
5. What’s the least number of birds that can be chosen from the beard to be sure that at least 1 is a lark?
6. What’s the largest number that can be chosen without having any larks?
7. What’s the least number that can be chosen so that at least 2 birds must be of the same kind?
8. Another old man with a beard has an unlimited supply of owls, hens, larks, and wrens and wishes to choose 8 birds to nest in his beard. How many different distributions, i.e., assortments, such as 3 owls, 2 hens, no larks, and 3 wrens, can he choose?

Sales plays an important role in allowing a business to maintain long-term relationships with customers. Sales force structures can be critical in allowing companies to distribute their products to their customers effectively. Typical sales force structures include territorial, customer, or product structures. Each structure has pros and cons. In addition, a sales force should be routinely evaluated to determine how effective it is in reaching company sales goals. The choice of how to compensate a sales force, whether through incentives, bonuses, or even contests, may also impact how effective a sales force is.

Imagine that you are the sales manager for a company that makes cabinet hardware, which it has traditionally sold to large contractors who build homes and offices. Your company has built a solid reputation and grown its business regionally, and it is now looking to sell its products to end consumers through national retailers such as Home Depot and Lowes. Your challenge is to create a sales force structure that will meet the expanding role of sales in your company.

In an essay, explain how you would:

structure the sales force. Explain why the structure you recommend is better than alternative approaches. compensate the sales force.

Explain why the approach you recommend would provide the right incentives for the sales force.

Question 2 There are 6 cities in Kilroy County.  The county must determine where to build central fire stations.  The county wants to build the minimum number of central fire stations needed to ensure that at least two fire stations are within 20 minutes (driving time) of each city. The times (in minutes) required to drive between the cities in Kilroy County are given in the table. Formulate a model that will tell Kilroy how many fire stations should be built and where they should be located.

1) Does Netflix have a strong brand? Offer evidence demonstrating why the firm’s brand is or isn’t strong. How is a strong brand built?

2) Who are the rivals to the Netflix streaming effort? Do any of these firms have advantages that Netflix lacks? What are these advantages?

3) Is Netflix a friend or foe to the studios? Make a list of reasons why they would ‘like’ Netflix, and why studios might be fearful of the firm. What is disintermediation and what incentives do studios have to try to disintermediate Netflix?

4) What advantages does Netflix have over premium cable television channels? What advantages do these channels have over Netflix? Do you think this is a winner-take-all market, or that there is room enough for multiple players?

5)What has been the impact of Netflix move from single plan pricing to separate pricing for streaming and DVD-by-mail? What factors motivated this move? Do you think splitting the service into separate plans was a wise move? Why or why not? What errors did the firm make in the ‘Qwikster debacle’? What could the firm have done differently? Do you think this would have had a positive impact on the firm? Why or why not?

Thank you

Braxton Technologies, Inc., constructed a conveyor for A&G Warehousers that was completed and ready for use on January 1, 2018. A&G paid for the conveyor by issuing a $100,000, four-year note that specified 4% interest to be paid on December 31 of each year, and the note is to be repaid at the end of four years. The conveyor was custom-built for A&G, so its cash price was unknown. By comparison with similar transactions it was determined that a reasonable interest rate was 12%. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)

Required:

1. Prepare the journal entry for A&G’s purchase of the conveyor on January 1, 2018.
2. Prepare an amortization schedule for the four-year term of the note.
3. Prepare the journal entry for A&G’s third interest payment on December 31, 2020.
4. If A&G’s note had been an installment note to be paid in four equal payments at the end of each year beginning December 31, 2018, what would be the amount of each installment?
5. By considering the installment payment of required 4. Prepare an amortization schedule for the four-year term of the installment note.
6. Prepare the journal entry for A&G’s third installment payment on December 31, 2020.

Can you please tell me what more information I need to provide to solve below problem?

1. Find out below using R

Hints: Use iris dataset from R (built in data set in R)

a) Create a new data frame called virginica.versicolor (that only contains these two species)

the command I used:

virginica.versicolor <- iris[iris$Species %in% c("versicolor", "virginica"), ]

b) What is your null hypothesis regarding sepal lengths for the two species (virginica.versicolor) ? And what is your alternate hypothesis?

c) Describe your hypotheses in terms of your test statistic: what would be the t under the null hypothesis, H₀, and what would be the statement about t under your alternate hypothesis Ha?

d) Would you do a one- or non-(i.e., two-sided) directional test? Why?

e) Conduct a Student’s t-test using the formula format as follows:

t.test(sepal.length ~ species, data = virginica.versicolor, var.equal = T).

f) Explain what the three different sections do within the t.test() function.

g) Did your function run a one- or non-directional test?

h) What is your t-value? Based on the results of your t-test, what is your conclusion and why?

Language: Python

Function name : sort_by_rating
Parameters : file (.csv file), category (string), order (boolean)
Returns: None
Description : You want to see what order the items of a particular category in your file would be in if you sorted them by rating. Given a file, a category of clothing, and an order boolean (True for ascending order, False for descending order), create a function that writes a file called “sorted_items.csv” that includes all of the items in the specified category in sorted order by ranking.
The format of the file should look like this:

(NOTE: there will be a header row at the top of each .csv file)

Note: If your input file contains no items in the specified category, your “sorted_items.csv” file should still be created and have the header row. Also, your written files should end in a new line character
Hint : You can use the built-in Python .sort() method on a list of tuples. The tuples will get sorted by the first item in each tuple. Example:
>>> list_of_tups = [(5, "cats"), (6, "kittens"), (1, "lizards")] >>> list_of_tups.sort()
>>> print(list_of_tups)
[(1, 'lizards'), (5, 'cats'), (6, 'kittens')]

Test cases:

>>> sort_by_rating("uniqlo.csv","tops",True)
