Careforall, The mayor of sickcity, claimed that his residents are very elastic and highly sensitive when the price of preventative care changes but not so sensitive when the price of inpatient care changes. To prove her point she referred back to the RAND studies. She claimed that the results of a replicated study in her town are shown below
Plan Average # of preventative care visits Average # of inpatient visits
Free 3.2 0.126
25% 2.54 0.122
50% 2.10 0.118
Careforall claimed that the best solution for her city is to provide free health care for all. The insurance companies replied that they will not be able to provide such a service. As a health adviser, you need to draft a proposal where you can design a health coverage that will be optimum for the citizen and provide insurance companies with a profitable market. Assume that the average cost of a preventative visit is $75 and the average cost of an inpatient care is $2700 and that the current plan ask patients to contribute 25% of the cost as a copay.

Monroe County is trying to determine where to place the county fire station. The locations of the county’s four major towns are as follows: (10, 20), (60, 20), (40, 30), and (80, 60) (see Figure 7.50). Town 1 averages 40 fires per year; town 2, 25 fires; town 3, 20 fires; and town 4, 30 fires. The county wants to build the fire station in a location that minimizes the average distance that a fire engine must travel to respond to a fire. Because most roads run in either an east-west or a north-south direction, the fire engine must do the same. For example, if the fire station is located at (30, 40) and a fire occurs at town 4, the fire engine has to travel miles to the fire.
Determine where the fire station should be located.
Use SolverTable to see how the optimal location of the fire station changes as the number of fires at town 3 changes.

Transaction Control
Transaction control involves coordinating multiple concurrent accesses to the same data. When one session is changing data that another session is accessing, Oracle uses transactions to control which users have visibility to changing data and when they can see the changed data. Transactions represent an atomic unit of work. All changes to data in a transaction are applied together or rolled back (undone) together. Transactions provide data consistency in the event of a user-process failure or system failure.
In your organization, the company's CIO is concerned about incidents in which statements committed changes without finishing up the whole series of statements. These incidents caused the data to be inconsistent, with errors in the later statements that did not get changed.
Write a memo in which you address how the use of transactions can help resolve this issue. Provide example database setup. Explain the importance of an atomic transaction.

As an independent governmental agency, the Bank of Canada is in charge of implementing monetary policies to achieve its major objectives. What are those objectives, and what policy tools does the Bank exercise to meet them? Explain the transition mechanisms through which changes in policy variables affect the economy. (You are welcome to “chose” the state of the economy – slumping or fast growing with a threat of inflation, and progress your policy recommendations and analysis based on your scenario. You should mention how you understand contractionary/expansionary monetary policies, the tools in the hand of the Central Banks to use, methods (OMO, inflation targeting, interest rate setting, etc. as well as the channels those changes may impact the economic indicators such as GDP, unemployment and inflation. You do not need to discuss all possible transmission mechanisms channels, just stick with one that you think is the most plausible and develop your logic.)

True or false
1. the control function gathers feedback to ensure that plans are being followed.
2. when the benefits of a potential decision are greater than the cost, the decision should usually be made.
3. decision making involves making a selection among competing alternatives
4.period cost involve direct: materials, director labor, and manifacturing overhead.
5. a good example of a cost diverter production labor wages is the number of machine hours
6. a fixed cost changes in direct proportion to changes in a cost driver .
7. the income statement can be expressed as sales - variable expenses fixed expense = net operating income
8. CM is used first to cover fixed expenses . any remaining CM contributes in net operating income
9. committed fixed cost are long-term and cannot be significantly reduced in the short term.
1o. in the mixed-cost equation: y=a+bx, the a is the slope

written and graphical analysis of the Covid outbreak in terms of Aggregate Supply and Demand. Specifically, - Is the pandemic a supply shock or demand shock? Why? (You can tell by the changes in prices, employment, and GDP) - If the economy self-corrects over time, what would happen to the above variables? Why? (Discuss how SRAS would change) - Has there been a permanent change in the economy's natural level of output / potential GDP? (i.e., has the LRAS curve shifted and why? Note that if LRAS changes along with the shock, there may not be a self-correction) - Are there Keynesian (sticky price) factors that would hinder self-correction? - What types of economic policies do you recommend? Fiscal or monetary? Expansionary or contractionary? Why? Include 1) AS/AD graph(s) that support the argument and 2) at least two cited references to economic data (GDP, unemployment rate, inflation rate, etc.) that would support your argument

Present and Future Values of Single Cash Flows for Different Interest Rates
Use both the TVM equations and a financial calculator to find the following values. Round your answers to the nearest cent. (Hint: Using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in parts b and d, and in many other situations, to see how changes in input variables affect the output variable.)

Consider a Carnot-cycle heat pump with R-410a as the working fluid. Heat is rejected from the R410a at 35 oC, during which process the R-410a changes from saturated vapor to saturated liquid.
