The researcher from problem 1 has a graduate student who is exploring doing his master's degree in the area of community-based mental health services. The student wants to assess whether the public health agencies in the southern part of the state have fewer resources than the agencies in the northern part of the state. He obtained survey data from a convenience sample of 12 agencies, 6 from the northern region and 6 from the southern region. The survey items used this response scale about their funding: 3 = more than enough funding, 2 = about enough funding, 1 = not enough funding (the survey did not interval level data). Here are the data:

Northern: 3, 3, 2, 1, 3, 2

Southern: 2, 1, 3, 2, 1, 2

Suppose you plan on eating 50 potato chips. As you start consuming potato chips, your marginal utility is very high, but it begins to fall slowly until you’ve eaten 10 chips. After you have eaten 10 chips, your marginal utility decreases even faster with each additional chip. Marginal utility continues to decline until you’ve eaten 49 chips. The fiftieth chip does not give you any additional utility. After 50 chips, your mouth gets so salty that it is unpleasant to eat any more, so marginal utility is actually negative for those chips. How many chips should you eat in order to maximize your total utility?

Implement a recursive algorithm to compute the product of two integers (in java). Your algorithm can only perform addition and subtraction; no multiplication. Analyze the running time and space complexity of your solution.

Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 120. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 80 and 50 bytes of data, respectively. In the first segment, the sequence number is 121, the source port number is 30058, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A.

In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number?

If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number?

If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?

Two isotopes of carbon, carbon-12 and carbon-13, have masses of 1.993 10-26 kg and 2.159 10-26 kg, respectively. These two isotopes are singly ionized (+e) and each is given a speed of 7.88 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.8400 T.

Determine the spatial separation between the two isotopes after they have traveled through a half-circle.

Calculate the ultimate biochemical oxygen demand (BOD) and the total organic carbon (TOC) concentration of an industrial wastewater containing 434 mg/L of organic matter that has been analyzed and found to have the empirical formula C9H15O5N and to be 100% biodegradable. Assume that no other organic, biodegradable or oxygen-demanding materials are present in the wastewater; and also assume that the nitrogen is converted to ammonia, NH3. Hints: a) although the molecular weight of the organic matter is not known, and may vary from one molecule to another, the formula weight can be used in similar fashion to convert mg/L to M; b) for completely biodegradable organic matter, the ultimate BOD is equal to the theoretical oxygen demand; and c) it is best to begin by writing the appropriate reaction and balancing it.

P.S. I know this is supposed to go in the Chemical Engineering subject but I can't find it. I have tried Civil Engineering but I have received no replies. Please help as much as you can.

A machine produces coins such that the probability of heads, p, follows a Beta distribution with parameters (α, β) = (1, 1). A coin produced by this machine is picked at random and tossed independently n times. Let Y be the number of heads.

1. (a) Find E[Y ].

2. (b) Write down the pmf for Y (your answer can include unevaluated integrals and

   combination numbers [aka “n choose m” symbols]).

Straws work on the principle of the outside atmospheric pressure pushing the fluid (for example water) up the straw after you have lowered the pressure at the top of the straw (in your mouth). Assuming you could create a perfect vacuum in your mouth, what is the longest vertical straw you could drink water from?

1.65 m

4.28 m

7.71 m

10.3 m

8)  How would this answer change if you were on a planet with a much lower atmospheric pressure?

increases

decreases

remains the same

9)  A block of wood (density 550 kg/m³) and a block of metal (density 2700 kg/m³) with equal volume are placed 1 m under water in a swimming pool. Which has a greater buoyant force on it?

the metal

the wood

they have the same buoyant force

10)  Which has a greater force of gravity on it?

the metal

the wood

they have the same force of gravity

11)  Compare the buoyant force to the force of gravity for each object.

In both cases the buoyant force is greater.

In both cases the force of gravity is greater.

For the metal, the buoyant force is greater; for the wood, the force of gravity is greater.

For the wood, the buoyant force is greater; for the metal, the force of gravity is greater.

12)  If they were taken to a depth of 10 m what would happen to the buoyant force on each (assume the density of water is constant and the objects are incompressible)?

they increase

they decrease

they remain the same

13)  If the objects were connected together, would they sink or float?

they would sink

they would float

they would stay right where the are!

For your main Discussion post, describe at least two typical adjusting entries a service-type business would need to record to bring account balances up-to-date. For your examples, one of the adjusting entries should be an accrual and another a deferral. You may use similar examples as those in your textbook and you may also research other typical adjusting entries for service-type companies. Be sure to address the following questions:

• What are the purposes of each of your example adjusting entries?
• Why are these adjusting entries required?
• What if the company does not record these adjusting entries? Would financial statements be accurate? Why or why not?
• Should the adjusting entries described be posted to the general ledger before preparing an adjusted trial balance? Why or why not?

Question 3:

2. Explain how the question in part (a) could be answered by constructing a 95% two-sided confidence interval for p.

Please provide an example of how MC.sim in R is to be used. The data can be made up, but please provide steps and explanations what to plug into that function. Thanks.

Java question:

Explain how class (static) variables and methods differ from their instance counterparts. Give an example of a class that contains at least one class variable and at least one class method. Explain why using a class variable and method rather than an instance variable and method would be the correct choice in the example you select.
