Assume a nation has an output level of 150 units per year, and that consumption is also 150. Suppose there is a sudden temporary drop in GDP by 16%. What does the long-run consumption path look like if this country has access to global financial markets with an interest rate of 5%?

1.) The speed of an electron is measured to within an uncertainty of 2.0x104 m/s. In how large a region of space is the electron likely to be found?

2.)The star nearest to Earth is Proxima Centauri, located at a distance of about 4.2 light years. (a) If one could travel there at 99% of the speed of light (0.99c), what would be the apparent distance to the star? (b) If you traveled to Proxmia Centauri at this high velocity, stayed there for 2 years, and then returned (also at 0.99c), how much time would have passed on Earth?

200.0 mL of 1.5 x 10^^-3 M Cu(NO3)² is mixed with 250.0 mL of 0.20 M NH3. The overall formation constant for the formation of the [Cu(NH3)⁴]²+ complex is 1.7·10¹³. (8 points)

The story must include 10 words from the following list: Fortune, appliance, fortnight, caution, creature, literature, access and cautious, nuisance, ruin, disastrous, distribute, counterfeit, certificate, collapse, gimmick, conscious, collection, magician, tragedy.

Thank you

review the research on fan violence, citing a specific example in the sport of your choice (including the URL). Fans have become more actively involved in spectator events in recent years (passive involvement vs. active involvement).

4. Compare the approaches of Fisher’s transactions and Pigou’s cash balances to the quantity theory. Are there any similarities between them? If so, in which respects? Or should they be treated as different approaches altogether?

Two suppliers have been contracted by a government agency to train agency employees learning to use a new computer system. The marginal cost curve of firm 1 is MC1=160+2Q1, while the marginal cost curve for Firm 2 is MC2=100+Q2, where Q is hours of training per week. Originally, each firm provides 60 hours of training services each week.

What is the total cost to firm 1 of providing 60 hours of training each week?

What is the total cost to firm 2 of providing 60 hours of training each week?

An economically-literate manager suggests it would be better to state a price that the government is willing to pay for an hour of training, and let each firm provide the number of hours they are willing to at this price.

What price should the government set to cost-effectively distribute the number of hours between the two firms while maintaining the total training provided at 120 hours per week?

How many hours of training will firm 1 provide at this price?

What is firm 1’s total cost?

How many hours will firm 2 provide at this price?

What is firm 2’s total cost?

How large is the cost savings resulting from the price rationed system relative to the original allocation of 60 training hours for each firm?

Instructions: Digital submission in PDF format (you can use Word or Markdown to create these and then convert to PDF). Your submission must include all R code.
I will be testing all of your code by copying and pasting into my R session, so make sure it works. Your solutions should be a narrative that incorporates R code (i.e. tell a story). R code by itself is not sufficient. This must be entirely an original work done by you. Copying someone else’s work (possibly found online) is not acceptable.

Assignment:

1) In homework 2, you gave the name of a site you would like to scrape. Follow through with this (you may change the site if you wish). The point of this exercise will be to ultimately provide an interesting visualization of the data which needs to be included in your solution. For this problem, the data must be scraped. Provide why you chose this site, and how someone would find your visualization useful (in other words, justify why anyone would care about this).

Given the information below, create the fully labeled Crow's Foot ERD using a specialization hierarchy where appropriate (use Visio). The ERD must contain all primary keys, foreign keys, and main attributes. Business rules are defined as follows: A small company sells products on-line. Each product is supplied by one supplier. Each supplier delivers only one product. Each product belongs to one of the following categories: Books, Movies, or CDs. All products have common attributes - a product code, a title and a price- and attributes that are unique for each group of products. The list of such attributes includes but is not limited to the following: the publisher name (books), the format (movies), and the rating (CDs). In addition, customers may purchase a book (hardcover or paperback) or its' electronic version. For regular books, the company wants to record the number of pages per book. For electronic books, the format and the size of the file must be recorded.

1, If we want to display output from a command, such as DIR or TYPE, one screen at a time, we can use what kind of command?

> MORE

| PAGE

| MORE

>> PAGE

2, To delete a directory that contains subdirectories and/or files, we will use what command:

DEL directory name /S

MD directory name /S

RD directory name /S

RMDIR directory name

3, When we are using certain tools (e.g. WMIC, DISKPART, and NETSH) in the Interactive Mode, most of the internal Command Prompt commands, such as CLS and CD, would not work. However, which command will work?

BYE

EXIT

| MORE

START

4, When we use this command in a batch file, the user must pick from the available options because Command Prompt won't let s/he pick anything else:

CHOICE

IF ELSE

FOR

Thalassines Kataskeves, S.A., of Greece makes marine equipment. The company has been experiencing losses on its bilge pump product line for several years. The most recent quarterly contribution format income statement for the bilge pump product line follows:

*Common costs allocated on the basis of machine-hours.

†Common costs allocated on the basis of sales dollars.

Discontinuing the bilge pump product line would not affect sales of other product lines and would have no effect on the company’s total general factory overhead or total Purchasing Department expenses.

Required:

a. Compute the increase or decrease of net operating income if the product line is continued or discontinued. (Decreases should be indicated by a minus sign.)

b. Would you recommend that the bilge pump product line be discontinued?

Give examples from the literature of metal complexes with coordination numbers (CN) of 2, 3, 4, 5, 6, 7 and 8 (formula, structure). What is the highest Coordination Number found for a metal ion?

a) Suppose each of the following confidence intervals were calculated using the same sample. Circle the interval that is at the lower confidence level. State the sample proportion that was used to construct these intervals. (.25, .35), (.24, .36)

b) Suppose you want a confidence interval to be more narrow. What two things can you do to achieve this?

c) For a given sample, which would you prefer, a wider interval or a more narrow one? Why?

d) Suppose your sample proportion is 0.17, with n = 100. How many “successes” were in your sample?

e) Suppose you have a sample with n = 27. Nine of your sample values are found to have the characteristic of interest. Are the 4 conditions required to do a confidence interval met?

f) True or False: a 95% confidence interval for p always contains p.

Hi Can someone explain how the the output was achieved in details for this java question?

public class Example
  
{
public static void main(String [] args)
{
int a = 6, b = 5, i , num1, num2;
for (i = 1; i <= 3; ++i)
{
num1 = method1(a, b);
num2 = method2 (a, b);
System.out.println (num1 + " " + num2);
a = a + 2;
b = b - 1;
}
}
public static int method1 (int c, int d)
{
c = c + d;
return c;
}
public static int method2 (int e, int f)
{
f = f + e * 2 ;
return f ;
}
}

Linda invest 25000 for one year part is invested at 5% another part at 6% and the rest at 8%. the total income from all three investments is $1600. the income from the 5% and 6% investments is the same as the income from the 8% investment. find the amount invested at each rate.
