Alleles for Sickle Cell Anemia occur at higher rates in some populations compared to others. Here, please explain what Sickle Cell Anemia is, how it is inherited, and why in spite of any negative side effects has it persisted as a trait among humans. Be as detailed as possible. You may even include a punnet square in your answer.

Cute Camel Woodcraft Company is a small firm, and several of its managers are worried about how soon the firm will be able to recover its initial investment from Project Sigma’s expected future cash flows. To answer this question, Cute Camel’s CFO has asked that you compute the project’s payback period using the following expected net cash flows and assuming that the cash flows are received evenly throughout each year.

Complete the following table and compute the project’s conventional payback period. For full credit, complete the entire table. (Note: Round the conventional payback period to two decimal places. If your answer is negative, be sure to use a minus sign in your answer.)

The conventional payback period ignores the time value of money, and this concerns Cute Camel’s CFO. He has now asked you to compute Sigma’s discounted payback period, assuming the company has a 9% cost of capital. Complete the following table and perform any necessary calculations. Round the discounted cash flow values to the nearest whole dollar, and the discounted payback period to two decimal places. For full credit, complete the entire table. (Note: If your answer is negative, be sure to use a minus sign in your answer.)

Which version of a project’s payback period should the CFO use when evaluating Project Sigma, given its theoretical superiority?

The discounted payback period

The regular payback period

One theoretical disadvantage of both payback methods—compared to the net present value method—is that they fail to consider the value of the cash flows beyond the point in time equal to the payback period.

How much value in this example does the discounted payback period method fail to recognize due to this theoretical deficiency?

In python language do thee following:

Some password scheme is designed such that the password must start with a special symbol in “$” “@” or “!” followed by four letters that could be in a..z followed by a similar special symbol followed by three letters in A..Z followed by a single digit. Write a program that takes from the user a string, and verifies whether the string abides by this password scheme. Do this once using regular expressions. Another time without using regular expressions.

A firm uses skilled labor, unskilled labor, and capital, and is initially in equilibrium. Suppose that the wage paid to unskilled labor falls, and that unskilled labor is a substitute in production with both skilled labor and capital. Depict in separate graphs of (a) capital and unskilled labor and (b) capital and skilled labor how the original equilibrium choices change in response to the decline in wages paid to unskilled workers. What are the expected impacts on the wage and employment level for each group of worker, and why? How does this factor into the growth of inequality in recent decades in the United States?

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 65 students enrolled in those two courses. Data concerning the company’s cost formulas appear below:

For example, administrative expenses should be $3,500 per month plus $45 per course plus $6 per student. The company’s sales should average $850 per student.

The company planned to run four courses with a total of 65 students; however, it actually ran four courses with a total of only 61 students. The actual operating results for September appear below:

Required:

Prepare a flexible budget performance report that shows both revenue and spending variances and activity variances for September (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

1. Friedman distinguishes between the two concepts that (a) businesses really do act in ways to maximize profit and (b) businesses have a moral responsibility (or, as he puts it, a social responsibility) to act to maximize profit. How does he defend the latter position? (See both the Friedman and Sandbu readings)
2. From the Sandbu article, Sandbu quotes Adam Smith as saying that we get our dinner from the self-interest of the butcher, baker and brewer. What does he mean by this? How does this observation lead to Adam Smith's concept of the "invisible hand?"

NB: Can I get an email to send both article?

Two stationary positive point charges, charge 1 of magnitude 3.85 nC and charge 2 of magnitude 2.00 nC , are separated by a distance of 43.0 cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed V_final of the electron when it is 10.0 cm from charge 1?

1) Describe the performance impact of using the LIKE operation with a wild card character at the beginning of the value.

2) Under what circumstances is a non-matching index scan performed?

3) A query is written to access a single table. Furthermore, that query will return only a single row because an equality predicate is coded on the primary key for the table. A unique index exists to support the primary key. What type of access is likely to be the most efficient for that query?

4) How can stored procedures be used to optimize performance in a client/server application?

5) Under what circumstances will a table scan outperform indexed access?

Create a base class called Shape which has 2 attributes: X and Y (positions on a Cartesian coordinate system). Since a shape is amorphous, set the class up so that an object of type Shape can not be instantiated.

Create three derived classes of your choice whose base class is Shape. These derived classes should have accessors/mutators for their class specific attributes, as well as methods to compute the area and the perimeter of the shape.

In main(), create a stack of pointers to Shape and push one object of each derived class onto the stack. Then, pop each shape pointer off of the stack and output that shape's area and perimeter, demonstrating polymorphism.

1. Mike and Suzanne have a daughter (Michelle) and a son (Jack). Michelle is 25 years old, working in a law firm. Jack is only 18 years old. Next year, Jack will start at the University of Adelaide as a student. As a family tradition, they have been doing lottery syndicate for years. They collect money and pay together, using their birthday numbers to play in the lottery. One day, Jack bought one lottery ticket, and later on, surprisingly found out he won 1 million Dollar. Now Jack wants to take all money for himself and leave his parents’ house to start a new life. Do you think Jack can do so? Would Mike, Suzanne and Michelle have any claim in this lotter?

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 15 engines and the mean pressure was 4.3 pounds/square inch with a standard deviation of 0.7. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.

Items are sometimes fastened to plastic parts by screw driven into smooth holes molded in the parts. Over time, however, the screws loosen. To what common laboratory test of viscoelasticity does this correspond? (Provide explanation)
