Briefly define, in your own words, the concepts of capitalism and socialism. Then list three pros and cons of each.

UK climate projections suggest a change in rainfall patterns. This will increase risk of flooding of cities from rivers. As a mitigation, a local lead flood authority is considering replacing the current temporary flood barriers with three different permanent gates to control the flood in different flood situations. The time required to complete each, and the number of workers required to be on the job at all times are shown in Table A below.

Table A. Specification ofthe flood barrier projects

Flood barrier gate - Duration of work [months] - Number of workers required

1 - 2 - 30

2 - 2 - 20

3 - 3 - 30

Once a flood gate is completed, it is estimated that it can control the following amount of water measured in cubic metres per month (cmm): gate I, 50cmm; gate 2, 30cmm; gate 3, 40cmm. For building these three gates, 60 workers are available during each month.

(a) Formulate a mathematical model in order to maximise, in the case of flood, the total water control capacity at the end of month 4.

(b) Formulate the following additional constraints forced by the tlood management committee:
(i) At most, construction on only one gate can be started during anyone month.
(ii) Gate 2 must be completed by the end of month 4.

a certain hospital is considering setting up a new facility. Management estimates that it will cost $1.5 million to purchase the necessary equipment and renovate the building to support its long term care services. The projected net cash flows generated by the new facility over the next five years are given below:

Year 1 -0

Year 2 $380,000

Year 3 $400,000

Year 4 $420,000

Year 5 $440,000

Assuming a five year life and 8% cost of capital, compute the net present value of this proposal. On the merits of your net present value computation, should this hospital invest in this project?

Identify what determinant changes and explain how the equilibrium price and equilibrium quantity in a purely competitive market will change given the following situations. Draw the appropriate demand and supply curves showing the change. (Each graph should have an equilibrium point before the impact as well as after; be sure to label all parts of the graphs).

a. Product: oranges – A winter storm freezes 50 % of the fruit on the trees in Florida

b. Product: avocados- A tariff is imposed on the importation of avocados from Mexico while demand remains the same.

c. Product: donuts – consumers desire for donuts decreases and the cost of flour (used to make donuts) increases

Explain in detail the shape of a perfectly competitive firm’s Total Revenue function and a monopoly's Total Revenue function. Explain why they are different.

A travel agent wants to estimate the proportion of vacationers who plan to travel outside the United States in the next 12 months. A random sample of 130 vacationers revealed that 40 had plans for foreign travel in that time frame. Construct a 95% confidence interval estimate of the population proportion. Make a statement about this in context of the problem

Adam Smith coined the Diamond Water Paradox. Where something that is essential to life has little value where something that does not has great value.

1.) Explain what theory Adam Smith was using and therefore was unable to explain why the paradox existed.

Describe the various reasons that anthropologists study performance by providing at least two specific examples.

A very large piece of carbon steel (? = 7854 kg/m3 , ? = 60.5 W/m·K, ?? = 434 J/kg·K) is initially at a temperature of 40°C. Suddenly, the flat surface of the steel is pressed into contact with an object at a temperature of 20°C. Which of the following is closest to the temperature of the steel at a location 10 mm from the flat surface after 0.5 s?

Knowing what you know now about how the various industries operate, when you proceed to the next steps in your career, either as an employee or as a business person, where will you concentrate on finding your place in the economy? Please provide some analysis of why you made this particular choice, using examples , and also please provide some choices you would not make, also using examples.

Write a program (preferably in Java) that, given an arithmetic expression,

• first transforms it to a postfix form, and then computes its value (by using stack-based algorithms).

Assume that all the numbers in the arithmetic expression are one-digit numbers, i.e., each of these numbers is either 0, or 1, or 2, ..., or 9. For example, your program should correctly process expressions like 2+3*4, but there is no need to process expressions like 11+22.

Implement a Composite Design Pattern for the code below that creates a family tree

MAIN:

public class Main {
public static void main(String[] args) {
/* Let's create a family tree (for instance like one used on genealogy sites).
For the sake of simplicity, assume an individual can have at most two children.
If an individual has 1-2 children, they are considered a "tree". If an individual
does not have children, they are considered a "person".
With that in mind, let's populate a family tree with some data. */
