n=33

(a) Let n be your special number. Construct a map of a continent having n different countries in such a way that four colours are needed to colour bordering countries in different colours. Using blue for the ocean (and possibly for some of the countries), and three other colours of your choice for the countries, apply colours to the map. [Use four colours whose names start with different letters, so that you can represent each colour with the first letter of its name.] (b) By inserting vertices at strategic locations, convert your map into a connected planar graph in which faces separated by an edge are differently coloured. (c) Construct the dual graph of your connected planar graph, and apply the corresponding vertex colouring to your dual graph.

Answers

Answer 1

(a) Given the exceptional number n = 33, let's draw a continent with 33 countries using four colours: blue for the ocean and three other colours representing their first letters.

Oceans are blue (B) on this map. Red (R), Green (G), and Yellow (Y) will represent the other colours.

Strategically inserting vertices turns the map into a connected planar graph. Add vertices at each country's centre. This creates a linked graph with coloured edges between faces.

(c) Switching vertices and faces in the connected planar graph creates the dual graph. The dual graph turns each vertex into a face and each face into a vertex. The dual graph connects vertices (former faces) that share an edge in the original graph.

The dual graph can be coloured using the same four colours: blue (B), red (R), green (G), and yellow (Y).

Following these methods, we produced a map of a continent with 33 countries, coloured it, transformed it into a connected planar graph with coloured faces, and created the dual graph with appropriate vertex colouring.

in your words why the
regulators require the parent entity to prepare consolidated
financial statements. (350 word)

Answers

Regulators require parent entity to prepare consolidated financial statements to provide comprehensive and accurate view of financial position, performance, cash flows of entire group, including subsidiaries.

Regulators require the preparation of consolidated financial statements for several reasons. Firstly, consolidated financial statements provide a holistic view of the financial affairs of a group of companies under the control of a parent entity. By consolidating the financial statements of the parent and its subsidiaries, regulators can assess the overall financial health and performance of the entire group. This is important for making informed decisions, evaluating the group's solvency, and ensuring compliance with regulatory requirements. Secondly, consolidated financial statements facilitate transparency and enhance the comparability of financial information. When a parent entity holds a controlling interest in its subsidiaries, it has the ability to influence and direct the operations and financial policies of those subsidiaries. Consolidation enables regulators and other stakeholders to assess the combined financial results and position of the group, rather than relying solely on separate financial statements of individual entities. This promotes transparency and helps investors, creditors, and other stakeholders in making more accurate and meaningful assessments of the group's performance and risks.

Furthermore, consolidated financial statements also play a crucial role in assessing the group's compliance with accounting standards and regulatory frameworks. By consolidating the financial statements, regulators can ensure that the group adheres to the prescribed accounting principles, disclosure requirements, and governance standards. This helps maintain the integrity and reliability of financial reporting within the group and protects the interests of stakeholders. Consolidated financial statements also provide valuable information for regulatory oversight and monitoring of the group's financial activities. Regulators can assess the group's overall risk exposure, evaluate its capital adequacy, and identify any potential issues or irregularities that may require regulatory intervention. By having access to consolidated financial statements, regulators can effectively fulfill their supervisory role and take appropriate actions to safeguard the interests of the public and maintain the stability of the financial system.

In summary, regulators require the preparation of consolidated financial statements to gain a comprehensive view of the group's financial position, promote transparency, enhance comparability, ensure compliance with accounting standards, and facilitate regulatory oversight. Consolidated financial statements provide a more accurate representation of the group's financial performance and enable regulators to make informed decisions and take appropriate actions when necessary.

Answers

:Suppose the average household income increases from $41 thousand to $64 thousand per year and we are asked to consider the market for Rainbow sandals.

The percentage change in the price of Rainbow sandals and the quantity of Rainbow sandals demanded can be calculated using the midpoint method.The formula for the percentage change in the price of Rainbow sandals using the midpoint method is:(Q2 - Q1) / [(Q1 + Q2) / 2] × 100where Q1 is the initial quantity demanded, and Q2 is the new quantity demanded after the change.The formula for the percentage change in the average price of Rainbow sandals using the midpoint method is:(P2 - P1) / [(P1 + P2) / 2] × 100where P1 is the initial price, and P2 is the new price.The midpoint formula for elasticity is:(Q2 - Q1) / [(Q1 + Q2) / 2] × 100 / (P2 - P1) / [(P1 + P2) / 2] × 100To compute the percentage change in the quantity of Rainbow sandals demanded, the midpoint formula can be used as follows:Using the midpoint formula:(Q2 - Q1) / [(Q1 + Q2) / 2] × 100= [(2400 - 2000) / [(2400 + 2000) / 2]] × 100= 400 / [4400 / 2] × 100= 400 / 2200 × 100= 18.18%The percentage change in the quantity of Rainbow sandals demanded is 18.18%.

The percentage change in the average price of Rainbow sandals using the midpoint method is calculated as follows:Using the midpoint formula:(P2 - P1) / [(P1 + P2) / 2] × 100= [($45 - $50) / [($45 + $50) / 2]] × 100= -$5 / [95 / 2] × 100= -$5 / 47.5 × 100= -10.53%The percentage change in the average price of Rainbow sandals using the midpoint method is -10.53%.The price elasticity of demand for Rainbow sandals is calculated using the midpoint formula.Using the midpoint formula:(Q2 - Q1) / [(Q1 + Q2) / 2] × 100 / (P2 - P1) / [(P1 + P2) / 2] × 100= 18.18% / (-10.53%)= -1.73LONG ANSWER:Therefore, the elasticity of demand for Rainbow sandals is -1.73. This implies that Rainbow sandals are elastic, and a 1% change in the average price of Rainbow sandals would cause a 1.73% change in the quantity of Rainbow sandals demanded. A household that earns an additional $23,000 per year can buy more Rainbow sandals, and the percentage change in quantity demanded is 18.18%. This increase in quantity demanded is significant, but it is still not enough to offset the loss in revenue caused by the decrease in the price of Rainbow sandals. A decrease in the price of Rainbow sandals would result in a 10.53% decrease in the average price of Rainbow sandals, which is significant and will result in a decrease in the total revenue from the sale of Rainbow sandals.

Answers

Based on this ratio, the NPV is less than the initial investment, indicating that the company would not have generated enough cash flow to cover the initial investment over the five-year period. Ratio = 0.0154.

Given that Scenario C involves selling the investment for $420,000 post-tax, we can calculate the NPV (Net Present Value) using the following formula:

Now, we need to compare this NPV to the initial investment of $22,000,000.

Initial Investment =  22,000,000

NPV=327,571.43

Ratio = NPV / Initial Investment

= 327,571.43/ 22,000,000

Ratio = 0.0154

However, it's important to note that this calculation assumes that the company will not receive any additional cash flow beyond the initial investment. If there are any additional opportunities for growth or investment, the NPV may be different.

Required dinontor on the Economy Society

Answers

The Mariana Dam disaster had significant impacts on both the economy and society. The following points highlight some of the effects:

Economic Impact: Environmental damage: The release of millions of tonnes of toxic mud caused extensive environmental damage, including pollution of the Rio Doce river. This had a direct impact on the region's ecosystem, affecting fish populations and threatening the livelihoods of fishermen who depend on the river for their income.

Disruption of economic activities: The disaster disrupted various economic activities in the affected region. The destruction of Bento Rodrigues and displacement of residents resulted in the loss of homes and affected local businesses. The region's mineral water supplies were also affected, impacting the bottled water industry.

Social Impact: Loss of lives and displacement: The disaster resulted in the loss of at least 17 lives and the displacement of hundreds of people. Entire communities, such as Bento Rodrigues, were wiped off the map, causing immense trauma and emotional distress to the affected individuals and families.

Social and cultural disruption: The disaster disrupted the social fabric and cultural heritage of the affected communities. The loss of homes, infrastructure, and historical sites had long-lasting social implications, as people had to rebuild their lives and communities from scratch.

The financial penalties imposed on the mining companies involved (Samarco, Vale, and BHP) reflect the recognition of the economic and societal damages caused by the disaster. The increased fine highlights the severity of the impact and the responsibility of the companies to compensate for the damages. Efforts to restore the environment and support the affected communities are essential to mitigate the long-term consequences on the economy and society.

Answers

The NPV (Net Present Value) of the project for Volvox Foundry Company is $590,850, which is negative.

To calculate the NPV, we need to discount the cash flows to their present values using the provided discount rates and PV factors. The cash flows for each year are $1,250,000, $1,350,000, $2,400,000, and $1,150,000 for years 1, 2, 3, and 4 respectively. Using the PV factors for a discount rate of 15%, we multiply each cash flow by the corresponding PV factor and sum them up:

NPV = ($1,250,000 * 0.87) + ($1,350,000 * 0.756) + ($2,400,000 * 0.658) + ($1,150,000 * 0.572) = $590,850 (rounded to the nearest dollar)

Since the NPV is negative, it indicates that the present value of the cash inflows from the project is less than the initial investment of $5,000,000. This suggests that the project may not generate enough returns to cover the cost of the investment and may result in a financial loss for the company. Therefore, the correct answer is: $590,850 negative.

Inventory costing methods help in estimating the value of inventory available for sale at the end of the period. Two inventory costing methods are FIFO and LIFO.FIFO (First-In, First-Out) assumes that the earliest goods purchased are the first ones sold. In contrast, LIFO (Last-In, First-Out) assumes that the most recently acquired items are the first to be sold.FIFO Method: Based on the FIFO method, the cost of the first eight units sold comes from the first eight units purchased for $24 each. Thus, the cost of the first eight units sold is 8 × $24 = $192.The next seven units sold come from the $30 stock bought on April 11. The cost of the next seven units sold is 7 × $30 = $210.The last six units sold come from the $19 stock bought on May 17. The cost of the last six units sold is 6 × $19 = $114.The dollar cost of the inventory sold is $192 + $210 + $114 = $516.LIFO Method: Based on the LIFO method, the cost of the last six units sold comes from the six units purchased for $19 each on May 17. Thus, the cost of the last six units sold is 6 × $19 = $114.The next seven units sold come from the $30 stock bought on April 11. The cost of the next seven units sold is 7 × $30 = $210.The first eight units sold come from the $24 stock bought on Jan 1. The cost of the first eight units sold is 8 × $24 = $192.The dollar cost of the inventory sold is $114 + $210 + $192 = $516.The calculation shows that the dollar cost of the inventory sold under both FIFO and LIFO is the same, $516.

the market is a cournot market
P = 1000 – 4Q
TC1 = 50 + q1 + 5q12
TC2 = 50 + 4.9q2 + 2q22

find profit max quantity of firm 2
q2=?

Answers

To find the profit-maximizing quantity for firm 2 in a Cournot market, we need to calculate the reaction function of firm 2 and then solve for the quantity that maximizes its profit.

First, we need to determine the reaction function of Firm 2, which represents its best response to the quantity chosen by Firm 1. In a Cournot model, each firm assumes that its competitor's quantity is fixed when deciding its own quantity.

The reaction function for firm 2 can be derived by maximizing its profit function, which is given by total revenue minus total cost:

Profit2 = (P - MC2) x q2 = (1000 - 4Q - 4.9q2 - 2q22) x q2

To find the profit-maximizing quantity, we differentiate the profit function with respect to q2 and set it equal to zero:

[tex]\frac{d(Profit2)}{dq2}[/tex] = (1000 - 4Q - 4.9q2 - 2q22) - (4.9q2 + 2q22) = 1000 - 4Q - 9.8q2 = 0

Solving for q2, we can substitute the given quantity Q into the equation and solve for q2. However, since the quantity Q is not provided in the question, it is not possible to determine the specific value of q2 without additional information.

a. Let U(X, Y) = min [X, ½Y] and Px = 10, Py = 20 and income M =
1000. Find optimal X, Y, and
the resulting Utility.
b. Now let Px = 12. How does optimal consumption and utility
change? E

Answers

a. To find the optimal X and Y that maximize utility, we need to compare the marginal utilities per dollar spent on each good.

Given U(X, Y) = min[X, ½Y], we can start by setting up the following equations:

MUx/Px = MUy/Py, where MUx and MUy are the marginal utilities of X and Y, respectively.

Since U(X, Y) = min[X, ½Y], we have:

MUx = 1 when X < ½Y, and MUx = 0 when X > ½Y.

MUy = ½ when X > ½Y, and MUy = 0 when X < ½Y.

Considering Px = 10 and Py = 20, we can set up the equations as follows:

1/10 = ½MUy/20  =>  MUy = 10

1/10 = 0/20  =>  MUx = 0

To maximize utility, we should allocate our budget in a way that MUx/MUy = Px/Py. However, since MUx = 0, this equation is satisfied regardless of the allocation between X and Y.

Given an income of M = 1000, we can calculate the amount of X and Y:

10X + 20Y = 1000

X + 2Y = 100

Let's assume X = 0 (as MUx = 0), then we have:

2Y = 100

Y = 50

So, the optimal consumption is X = 0 and Y = 50.

To find the resulting utility, we substitute the values of X and Y into the utility function:

U(X, Y) = min[0, ½ * 50] = min[0, 25] = 0

Therefore, the resulting utility is 0.

b. Now, let's consider Px = 12. The equations for marginal utilities remain the same:

1/12 = ½MUy/20  =>  MUy = 40/3

1/12 = 0/20  =>  MUx = 0

Since MUx = 0, the equation MUx/MUy = Px/Py is again satisfied regardless of the allocation between X and Y.

Using the income of M = 1000, we can calculate the amount of X and Y:

12X + 20Y = 1000

X + 5/3Y = 100

Assuming X = 0, we have:

5/3Y = 100

Y = 60

So, the optimal consumption is X = 0 and Y = 60.

Substituting the values of X and Y into the utility function:

U(X, Y) = min[0, ½ * 60] = min[0, 30] = 0

Therefore, the resulting utility is still 0.

In summary, when Px increases from 10 to 12, the optimal consumption and resulting utility remain the same. The change in Px does not affect the allocation between X and Y or the utility derived from consuming the goods.

You are considering the investment of $1,000 in stock A, B, and T-bill. The probability distributions of assets are as follows. The covariance of stock A and B is 0 Stock A Stock B T-bill Expected return 10% 5% 2% Standard deviation 10% 5 0 (1) What is the investment weight on stock A and B at the optimal risky portfolio? (2) If you place 90% of your money in optimal risky portfolio and 10% in T-bill, what is the proportion invested in the T-bill and each of the two stocks? (3) In (2), what is the expected return and standard deviation at the complete portfolio? (4) Which stock would be chosen if you select one stock with higher the Sharpe ratio?

Answers

1.  The covariance between stock A and B is 0, the variance simplifies to: Varp = (wA^2 * Vara) + (wB^2 * Varb)

2. Proportion in stock B = 90% * wB

3. Varc = (pA^2 * Vara) + (pB^2 * Varb) + (pT^2 * Vart)

4. SR = (ER - Rf) / SD

(1) To find the investment weights on stock A and B at the optimal risky portfolio, we need to calculate the portfolio's expected return and variance. Since the covariance between stock A and B is given as 0, there is no correlation between them, and the portfolio's variance simplifies.

The expected return of the optimal risky portfolio (ERp) can be calculated as the weighted sum of the expected returns of stock A (ERa) and stock B (ERb) using the investment weights (wA and wB):

ERp = wA * ERa + wB * ERb

The variance of the optimal risky portfolio (Varp) can be calculated as the weighted sum of the variances of stock A (Vara) and stock B (Varb) using the investment weights and considering the covariance:

Varp = (wA^2 * Vara) + (wB^2 * Varb) + 2 * wA * wB * Cov(A, B)

Since the covariance between stock A and B is 0, the variance simplifies to:

Varp = (wA^2 * Vara) + (wB^2 * Varb)

(2) If 90% of the money is invested in the optimal risky portfolio and 10% in T-bill, the proportion invested in the T-bill is 10%, and the proportion invested in each of the two stocks (A and B) can be calculated using the investment weights and the remaining 90% of the money:

Proportion in T-bill = 10%

Proportion in stock A = 90% * wA

Proportion in stock B = 90% * wB

(3) To calculate the expected return and standard deviation of the complete portfolio, we need to consider the proportions invested in each asset. Let's denote the proportions as pA, pB, and pT for stock A, stock B, and T-bill, respectively.

Expected return of the complete portfolio (ERc) can be calculated as:

ERc = pA * ERa + pB * ERb + pT * ERt

Since the T-bill has an expected return of 2%, ERt = 2%.

The variance of the complete portfolio (Varc) can be calculated as:

Varc = (pA^2 * Vara) + (pB^2 * Varb) + (pT^2 * Vart) + 2 * pA * pB * Cov(A, B) + 2 * pA * pT * Cov(A, T) + 2 * pB * pT * Cov(B, T)

Given that the covariance between stock A and T-bill (Cov(A, T)) and the covariance between stock B and T-bill (Cov(B, T)) are both 0, the variance simplifies to:

Varc = (pA^2 * Vara) + (pB^2 * Varb) + (pT^2 * Vart)

(4) To determine the stock with a higher Sharpe ratio, we need to calculate the Sharpe ratio for each stock. The Sharpe ratio measures the risk-adjusted return of an asset.

Sharpe ratio (SR) can be calculated as:

SR = (ER - Rf) / SD

Where ER is the expected return of the asset, Rf is the risk-free rate (T-bill rate), and SD is the standard deviation of the asset.

The company pays 100% of group term life insurance premiums for its employees as a non-cash taxable benefit which for Mary's is $23.00 per pay period, Mary is a member of the company's registered pension plan and contributes 3% of her salary to the plan every pay. Her federal and Alberta TD1 claim codes are 1. Determine Mary's total income tax deduction per pay period. Your answer:

Answers

Mary's total income tax deduction per pay period is $236.06.

Mary's total income tax deduction per pay period is $236.06.WORD COUNT: 100. Explanation:

Total Salary = $40,000.00/yr

Salary per pay period = $40,000.00 / 26 pay periods = $1,538.46. Car allowance per pay period = $100.00

Group term life insurance per pay period = $23.00.

Pension contribution per pay period = 3% of salary = 3/100 x $1,538.46 = $46.15Gross pay per pay period = $1,707.61

Federal TD1 claim code = 1

Alberta TD1 claim code = 1

Income tax deduction per pay period can be calculated as follows: Federal tax payable = ($1,538.46 - $122.92) x 15% - $463.19 = $53.29

Alberta tax payable = ($1,538.46 - $131.54) x 10% - $171.29 = $82.60CPP contribution = ($1,707.61 - $57.40) x 5.10% = $82.72

EI premium = ($1,707.61 - $57.40) x 1.58% = $25.40

Total income tax deduction per pay period =

Federal tax payable + Alberta tax payable + CPP contribution + EI premium= $53.29 + $82.60 + $82.72 + $25.40 = $236.06.

Therefore, Mary's total income tax deduction per pay period is $236.06.

the correlation coefficient between two assets equals ____

Answers

However, the answer requires a long answer as there are several factors that can impact the correlation coefficient between two assets. The correlation coefficient measures the strength and direction of the linear relationship between two variables.

In the case of assets, it measures how closely the returns of the two assets move together. The correlation coefficient can range from -1 to +1, with -1 indicating a perfect negative correlation (meaning the two assets move in opposite directions), +1 indicating a perfect positive correlation (meaning the two assets move in the same direction), and 0 indicating no correlation (meaning there is no relationship between the two assets).

To calculate the correlation coefficient between two assets, you will need to have historical returns data for both assets. Once you have this data, you can use a statistical software or tool to calculate the correlation coefficient. It's important to note that the correlation coefficient is not a measure of causation, meaning it doesn't tell you why the two assets are moving together (or not). It simply tells you how closely they are moving together.

In summary, the correlation coefficient between two assets is a measure of the strength and direction of the linear relationship between their returns. It can range from -1 to +1, with -1 indicating a perfect negative correlation, +1 indicating a perfect positive correlation, and 0 indicating no correlation. To calculate the correlation coefficient, you will need historical returns data for both assets and a statistical software or tool.
