The development of linear programming is perhaps among the most important scientific advances of the mid-20th century. Today, it is one of the standard tools that has saved many millions of dollars for most companies and enterprises.
Identify at least two reasons for the importance of linear programming in an enterprise of your choice and describe the impact that linear programming has had in that enterprise in recent decades. Provide a specific example of a linear programming model related to the enterprise that you have selected and interpret the slack variables of your example. Describe how the information obtained about the slack variables of your example can be used by the decision-making sector of that enterprise. (You do not have to write a mathematical formulation of your example. Simply mention the objective, the decision variables, and a few possible constraints to describe your model example).

Recall from Activities 16-1 and 16-3 that the Kaiser Family Foundation commissioned an extensive survey in 2004 that investigated the degree to which American youths aged 8–18 have access to various forms of media. Of the 1036 girls in the sample, 64% had a television in their bedrooms, compared to 72% of the 996 boys in the sample.
a. Suppose you want to use these sample results to produce a 95% confidence interval for πg - πb. Describe in words what πg - πb represents.
b. Calculate this interval, and interpret what it reveals. Be sure to mention whether the interval contains all negative values, all positive values, or some of each.
c. Calculate a 99% confidence interval for πg - πb. Comment on how its midpoint and width compare to the 95% interval

Bacteria can perform aerobic and anaerobic respiration depending on their enzymes and metabolic needs. A student argued that aerobic and anaerobic respiration should produce the same amount of ATP. He reasoned that they both use basically the same process; only the terminal electron acceptor is different. What is the primary error in this student’s argument? Think about the different organisms in the body and in nature. Discuss how some produce their energy by anaerobic and aerobic metabolism. Discuss what would be available to them in this environment and what would they use as a primary electron acceptor. Would they all produce the same amount of ATP (energy) ? Within your discussion, mention a specific bacteria that uses aerobic, or anaerobic, aerotolerant, facultative anaerobic metabolism etc. Include a link to your source not previously posted.

Question 4 Flash Inc. was founded 5 years ago. It has been profitable for the last 2 years, but it has needed all of its earnings to support growth and thus has never paid a dividend. Management has indicated that it plans to pay a $1 dividend starting from today, then it will increase the dividend growth by 50% for the next two years, and then the company will achieve a long run growth rate of 7.5%. Assuming a required return of 12%, what is your estimate of the stock's intrinsic value today?
a) Calculate the Flash Inc. non-constant dividends.
b) Calculate the Flash Inc. horizon value.
c) What is the firm's intrinsic value today, P̂ 0?
Mention the appropriate BA II Plus keys (where required).

Your company's MARR is 9%.. Your boss wants to buy a new piece of
rental equipment - a snow making machine - which she plans to rent
to local ski clubs. The estimated cost of the machine is $55,000
and the annual O&M is $6000. She expects to rent the machine at
$16,000 per season for 7 seasons, at which time Global Warming will
end the ski industry. However the snow machine can be sold as an
antique at an estimated price of $20,000. A. Does this sound like a good investment? [copy the pertinent value before you start part B.] B. You mention to boss that it does not sound bad, but the salvage value sounds too high. She asks you to find the value of the salvage value at which the investment will just break even. |

Learning: Operant Conditioning
Psychologists like B. F. Skinner have studied how we can use
operant conditioning to change the behavior of people and animals.
Drawing on your personal experience, choose a person or animal
whose behavior you want to change. (You may select your own
behavior for this question if you wish.) How could you use operant
conditioning to change the behavior of this person or animal?
In a multi-paragraph essay, describe your plan to change this
behavior. Be sure to mention what type of reinforcer and
reinforcement schedule you would use and explain why you made those
particular choices. Include information from class materials,
readings, and research on operant conditioning to support your
discussion.

A 65.0 mL sample of 1.0 M NaOH is mixed with 48.0 mL of 1.0 M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid through which passes a calibrated thermometer. The temperature of each solution before mixing is 24.4°C. After adding the NaOH solution to the coffee cup, the mixed solutions are stirred until reaction is complete. Assume that the density of the mixed solutions is 1.0 g/mL, that the specific heat of the mixed solutions is 4.18 J/(g •°C), and that no heat is lost to the surroundings. The ΔΗrxn for the neutralization of NaOH with H2SO4 is –114 kJ/mol H2SO4.
What is the maximum measured temperature in the Styrofoam cup? ---------
Also, 35.985 is incorrect as they mention at the site, "H2SO4 is not the limiting reagent. Remember to consider the stoichiometry of the balanced equation for the reaction".

Q.1) Based on your understanding of Aggregate tests answer the
following:
a. Show the differences between apparent specific gravity and
effective specific gravity by drawing sketches for their aggregate
particles.
b. Absorption and specific gravity are critical information for the
Hot Mix Asphalt design engineer, Why?
c. How you can make check that the fine aggregate sample reaches
the SSD case?
Q.2) Based on your understanding of Asphalt cement tests answer the
following:
a. Asphalt binder at room temperature is solid. To be able to mix
it with aggregate it must become liquid. How you can convert it to
a liquid material (show all methods)?
b. Is there a direct measure for asphalt binder aging? Mention it
or them and Explain your answer.
c. In solubility test AC should be moisture free, why?

1. Describe a transformation process within an organization that is familiar to you; list all inputs, components, and the transformation process that produces either a product or service the organization delivers its customers. Make sure you mention all of the parts of the transformation process.
2. What is the difference between a “products or goods” versus “services”? What are some of the similarities and differences between the two? Can services be inventoried? (Last Question is Lecture Based) Give some examples based upon your experience as a customer or from your professional experience.
3. Many people state that their organization has no customers. Is it possible for a business, or department within an enterprise, not to have customers? Why or why not? How does the customer influence an operations strategy? What is the difference between a strategy and an operations plan?
