The relationship between China and the United States is often in the news. To refresh your memory, here are four facts about the Chinese economy: 1. China manages its exchange rate with the dollar. 2. China runs a trade surplus with the United States. 3. The Chinese central bank owns a large number of U.S. Treasury bills. 4. Individual Chinese residents are not free to invest their savings in foreign countries as they would like. Any movement away from a managed exchange rate would probably include a relaxation of these restrictions.

Now evaluate the following claims below with three to five sentences for each. You should also feel free to use graphs or equations where appropriate. Your goal is to discuss why the claim is true, partially true, or not true at all.

i. “Cheap imports from China come a steep cost – lost jobs and lower wages for American workers.”

ii. “Over time, the Chinese government can maintain an unfair trading relationship with the United States by pegging its currency to the dollar at a low level.”

iii. “In the long run, if China continues to peg its currency to the dollar at an abnormally low value, it may incur a significant increase in its price level.”

iv. “The only way for the United States to close its bilateral trade deficit with China is to either raise national savings in the U.S. or reduce investment in new plant and equipment in the U.S.”

v. “Because China has a fixed exchange rate, it is unable to conduct discretionary monetary policy.”

vi. “If China stopped managing the value of its currency, the value of China’s currency would strengthen relative to the dollar and U.S. interest rates would rise.

Harvey is riding his bicycle, no-handed, and at a very fast speed down a park path. Trish, a jogger, accompanied by her dog, Rover on a leash is approaching Harvey from the other direction. Because he knows that he is bigger and faster on his bike, Harvey expects Trish to move out of his way. Unfortunately, Trish does not and as Harvey passes Trish, he side-swipes her knocking her to the ground and injuring her. Rover is inadvertently released when Trish falls, and he runs off into the road. Monty is driving carefully down the road. Seeing Rover running into his path and wanting to avoid hitting him, Monty swerves driving off the road and onto the sidewalk, damaging his wheel alignment when he jumps the curb. Grandma Jenkins is babysitting young Elvis, her grandson. Elvis happens to be playing hopscotch on the sidewalk across the street from the park. Fortunately, Monty's veering car stops far short of Elvis, and all is well for the tot (except for anxiety he suffered when he looked up and saw Monty's car heading straight for him). Unfortunately, Grandma Jenkins, observing the car veering off the road and heading straight toward her grandson, suffers a heart attack.

Analyze the following questions based on Negligence - (how far does Harvey's liability go? support)

Is Harvey liable for the injuries suffered by Trish and the loss of Rover? (Note: Rover is not dead, just lost) Is Harvey liable for the damage to Monty's car?

Is Harvey liable for the anxiety that Elvis suffered?

Is Harvey liable for Grandma Jenkins' heart attack?

For this assignment you have to create tables as reviewed in class Manufacturer table, Product table and Stock table. The code is in Week 7 PPT lecture. You are to add update as needed to make the tables the same as below and match Product, Manufacturer and Stock as below.

For this assignment you will be working with these same tables.  

Please complete the following tasks and submit in word file or notepad.

1. First insert tuples into two of the tables and make sure the contents of the tables match below.  

Write and execute the SQL to insert three records ProductID 844, 555 and 645 to the Product table (see below)

Write and execute the SQL to insert the one record to the Stock table (see below).  

2. Write and execute the SQL select statements to do the following selections of ALL TUPLES IN A TABLE

a. Select all (attributes) tuples in Product

b. Select all (attributes) tuples in Manufacturer

c. Select all (attributes) tuples in Stock

3. Write and execute the SQL select statements to do the following selections of ONLY SOME TUPLED IN A TABLE

a. Select Manufacturer ID = 1 tuples in Product table.

b. Select ProductID of Products that have a quantity of 300.

c. Select ProductID of Products that have quantity of 300 and less.

4. Write and execute the SQL select statements that select attributes (not all) based on a condition.

a. Select ProductID for items with ManufacturerID of 4.

b. Select ProductName for items with ManufacturerID of 1.

c. Select Products with the productName 'Keyboard'

5. Write and execute the SQL select statements that SELECT with and without DISTINCT modifier

a. Select ProductName and ManufacturerID from Product

b. Select Product Name and ManufacturerID from Product with the Distinct modifier.

c. Explain the difference in the results from a and b.

Question 3.[10 pt]

As indicated in the course book and discussed in the class extensively, there is

generally an efficiency trade-off among execution time, memory usage and communication

overhead for a given algorithm. Please give at least two examples where such a trade-off occurs.

For example, can you give an algorithm example wherein more storage permits faster execution,

or vice versa? Similarly, can you exemplify another algorithm wherein there are trade-offs

among communication and/or memory and/or execution time?

Algorithm Trade-off Example Brief Discussion 1 [5pt]:

Write a paragraph here by explaining the

name of the algorithm and how the performance trade-off.

Algorithm Trade-off Example Brief Discussion 2 [5pt]:

Write a paragraph here by explaining the

5

name of the algorithm and how the performance trade-off occurs.

Question 4. [30 pt]

In this exercise, we start getting familiar withtwo-dimensional arrays, i.e., a

matrix (remember that matrices are nothing but 2D arrays).Matrices are one of the most

fundamental data structures, and they are used in every aspect of Information Technology

including but not limited to AI, cyber-security and software engineering. The most basic

definition of a matrix is here:



https://www.mathsisfun.com/algebra/matrix-introduction.html

Specifically, as an example was given in the above link for 2x2 matrix, you will perform the

most basic arithmetic operation on a matrix,

adding two matrices entry-wise

. Please see the link

below and read

“Entrywise Sum”.

Each corresponding cell in a matrix is added and put into 3

rd

target matrix.



https://en.wikipedia.org/wiki/Matrix_addition

Write a program named “

hw2.py

” that will add two matrices entry-wise. The matrix dimension

is fixed and 5x5 for this exercise. Your program should print an error if the dimensions of the

two matrices are different. In this case, print a message stating that the matrix dimensions does

not match. There are two matrices to be added. One is shown in “hw2-m1.txt”

5 2 0 3 4

2 4 1 1 0

3 0 5 6 1

0 2 6 0 1

4 1 1 0 0

6

The other one is shown in “hw2-m2.txt”

2 0 4 0 1

2 2 1 0 5

0 0 1 0 3

2 1 0 4 1

0 0 4 0 1

Read these two matrices from “.txt” files, and use your own codes to add them,

donot use built-

in functions

. Finally, you should print the result on the screen as

The result is:

7 2 4 3 5

4 6 2 1 5

3 0 6 6 4

2 3 6 4 2

4 1 5 0 1

Name and define each trophic level in an ecosystem and cite an example for each level, using the following terms: producer, primary consumer, secondary consumer, tertiary consumer, decomposer, herbivore, carnivore, omnivore, autotroph, and heterotroph.

In two sentences differentiate between density-dependent and density-independent forces and their impact on population size.

What are the key differences between the three types of survivorship curves (Type I, Type II and Type III); give one example of an organism that exhibits each pattern and state in a sentence for each what traits inform you that it exhibits that strategy.

State seven ways humans make an impact on the environment through population size and/or the ecological footprint of its citizens.
