Consider and discuss the interactions between rising or falling costs, the quantity and profitability of products in a business environment. How does variable cost changes affect the contribution margin and profit as opposed to the changes in fixed costs? Provide life examples of how you see these costs in your personal life or business.

Two types of statistical data can be used to illustrate changes in encounters with death in American society: death rates and average life expectancy. How have these sets of data changed over the last hundred years in the U.S.? How have these changes affected your encounters with death, dying, and bereavement?

QUESTION 11

1. Which of the following is a statement of the principle of Hess's law?

   		If a reaction is carried out in a series of steps, the ΔH for the reaction will equal the product of the enthalpy changes for the individual steps - that is the multiplication of the enthalpy changes for the individual reactions you have manipulated.
   		The ΔH for a process in the forward direction is equal to the ΔH for the process in the reverse direction.
   		The ΔH for a process in the forward direction is equal in magnitude and opposite in sign to the ΔH for the process in the reverse direction.
   		If a reaction is carried out in a series of steps, the ΔH for the reaction will equal the sum of the enthalpy changes for the individual steps - that is the addition of the enthalpy changes for the individual reactions you have manipulated.
   		The ΔH of a reaction depends on the physical states of the reactants and products.

QUESTION 12

1. A coffee cup calorimeter is usually used for determining:

   		the heat of combustion of gaseous reactions
   		the molar heat capacity of pure elements
   		the heat of reaction of aqueous reactions
   		the calories in food samples
   		the heat capacity of solid samples

Explain the differences between the simple Keynesian (demand-side) model and the classical (supply side) model with respect to fiscal policy, what can change Y (Real GDP), and any other things that you think are relevant.

To answer this question correctly, you would need to:

A) Explain why fiscal policy does not change the Yd curve in the classical model but does in the

simple Keynesian model.

B) Explain that in the classical model Y only changes if Ys changes.

C) Explain that in the simple Keynesian model Y only changes if E or Yd changes.

D) Explain that there is no limit to rises in Y in the simple Keynesian model, but there are in the

classical model.

E) Explain that taxes change Ys in classical model but not in simple Keynesian model.

F) Explain that simple Keynesian model explains equilibrium in terms of inventories changing.

Classical model does not do this.

Please provide graphs/diagrams along with your explanation.

FLSA Analysis

For this assignment, you will be researching the Fair Labor Standards Act (FLSA).

For the first section of your paper:

Assess the main features of the Fair Labor Standards Act (FLSA).
Compare the definitions of exempt and nonexempt employees.
Evaluate at least three criteria that differentiate an exempt and nonexempt employee.

In spring 2014, then-President Obama sent a memo to the US Department of Labor (DOL) Secretary directing reform of FLSA to address white-collar exemptions and, effectively, increase the number of employees entitled to overtime pay. Some changes have been approved and became effective as of December 2016. Research some of the revisions the DOL adopted such as an increase in minimum salary requirements and changes to the current “primary duty” test.

For the second section of your paper:

Analyze some of the controversies and objections associated with these modifications. Explain and justify your view--do these changes benefit employees or the employer? Do you prefer the previous FLSA law or the changes?

Minden Company manufactures a high-quality wooden birdhouse
that sells for $30 per unit. Variable costs are $6 per unit
and fixed costs total $180,000. During 2018, Minden Company
sold 50,000 birdhouses to customers. The president of Minden
Company believes the following changes should be made in 2019:

1. the selling price of the birdhouse should be increased
   by 20%

2. increase advertising by $30,000

A.)Assume these changes are made. Calculate the number of units
Minden Company must sell in 2019 in order to break-even

B.) Assume these changes are made. Calculate the number of units Minden Company must sell in 2019 in order to earn a target profit equal to 25% of sales.

C.) Assume these changes are made. Calculate the number of units Minden Company must sell in 2019 in order to earn a net income that is 80% greater than the net income earned in 2018.

Need help with parts a,b and c. Thank you

The following are data from a small portion of the genome from four tetrapods.

Species: Sequence:

Chelonia mydas GACAG

Grus americana GACCG

Taricha granulosa GTACA

Zaglossus attenboroughi GTCAA

The challenge is to reconstruct the evolutionary ancestry of these four species from the molecular sequence information.

1.Phylogeny 1:

a. Draw a potential (unrooted) phylogenetic tree illustrating the possible relationships among these species.

b. Determine what (minimal) changes in sequence are required and where they must be located on the tree you have drawn in order to explain the observed sequences. Mark these on the tree above. HINT: it may be helpful to start with the sequences themselves at the tips of the tree.

c. How many (minimal) changes are required for this tree?

2. Phylogeny 2:

a. Draw a different potential (unrooted) phylogenetic tree illustrating the possible relationships among these species.

b.Mark the (minimal) changes on the tree above.

c. How many (minimal) changes are required for this tree?

Anglo American Platinum Limited is a major worldwide producer of platinum. Platinum is widely used in the production of catalytic converter. It is now August 1. The company is committed to selling 250 ounces of platinum on September 14. To hedge the risk, the company is considering using October futures contracts to offset the risk exposure. The standard deviation of monthly changes in the spot price of platinum per ounce is 30 and the standard deviation of monthly changes in the futures price of wheat per bushel the closest contract is 35. The correlation between the futures price changes and the spot price changes is 80. Each contract is for the delivery of 50 ounces platinum.

(a) What is the optimal hedge ratio?

(sample answer: 25.30%)

(b) Should the hedger take a long or short futures position?

(sample answer: long; or short)

(c) What is the optimal number of futures contracts with the hedge?

(sample answer: 12; it should be a whole number)

Advanced economies are emerging from the worst financial

recessions in modern times. Many developed nations

have implemented austerity measures to adjust the deficit

caused by massive spending during the years of cheap

and available credit facilities. New industrial policies are

also implemented at national and regional levels to police

banks and financial institutions as measures of avoiding

further economic problems in the future. The austerity

measures and policy changes have forced industries and

business practices to change.

1. What changes do you think this might cause in the

immediate task environment for a business operating

within the financial service industry?

2. How do these changes impact on corporate, business,

and functional level strategies of financial service

businesses? Are these changes going to affect

you as customers?

3. How do you think a learning organization would act

in this dynamic environment? What survival chances

do the stagnant organizations have?

The Levy Box plant produces wooden packing boxes to be used in the local seafood industry. Current operations allow the company to make 600 boxes per day, in two 8-hour shifts (300 boxes per shift). The company has introduced some moderate changes in equipment, and conducted appropriate job training, so that production levels have risen to 400 boxes per shift. Labor costs average $13 per hour for each of the 5 full-time workers on each shift. Capital costs were previously $4,000 per day, and rose to $4,200 per day with the equipment modifications. Energy costs were unchanged by the modifications, at $400 per day.

a) What is the firm's multifactor productivity (exhibit 2.5) before and after the changes?

b) What is the firm's labor hours productivity before and after the changes?

c) What is the percent change in the multifactor productivity before and after the changes?
