Write a program using MARIE’s assembly language. The program consists of a main program and a subroutine. It uses the subroutine to process a given number. If the value of the number is negative, the value will be replaced with zero and returned. Otherwise, the value is doubled and returned. Then, in the main program, it calls the subroutine to process for X = -3 and saves the value after the processing.

Write a fragment of code that uses two existing arrays of doubles, a and b, creates a third array c, and assigns each element of c to the average of the corresponding elements of a and b. You may assume that the arrays a and b are the same length. (java)

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?

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.
(a) Find E[Y ].
(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!
14) Water is flowing through a pipe that slowly gets smaller as it rises to the bathroom on your second floor (10 m high). The pipe coming into your house is 3 cm in diameter, the pressure there is 3x105 Pa, and the water is moving at .8 m/s. The diameter of the pipe in the upstairs bathroom is 1.5 cm. How fast is the water moving right before it leaves the pipe in the bathroom?
.2 m/s
.4 m/s
1.6 m/s
3.2 m/s
15) What is the pressure of the water in the pipe right before it leaves the pipe?
1.50x105 Pa
1.97x105 Pa
2.88x105 Pa
3.67x105 Pa
