Given some very common assembly language command, like, for example, the following instruction.

ADD ECX, EAC

Please, describe the main CPU algorithm, or, the major stages of the instruction processing executed by the CPU within the instruction cycle. Assume, no pipelining is available.

Elaborate on the benefits of internet marketplace based on the four aspects below.

4. Consider the following data drawn independently from normally distributed populations: (You may find it useful to reference the appropriate table: z table or t table)

a. Construct the 95% confidence interval for the difference between the population means. Assume the population variances are unknown but equal. (Round all intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.)

Confidence interval is to .

b. Specify the competing hypotheses in order to determine whether or not the population means differ.

• H₀: μ₁ − μ₂ = 0; H_A: μ₁ − μ₂ ≠ 0

• H₀: μ₁ − μ₂ ≥ 0; H_A: μ₁ − μ₂ < 0

• H₀: μ₁ − μ₂ ≤ 0; H_A: μ₁ − μ₂ > 0

c. Using the confidence interval from part a, can you reject the null hypothesis?

• Yes, since the confidence interval includes the hypothesized value of 0.

• No, since the confidence interval includes the hypothesized value of 0.

• Yes, since the confidence interval does not include the hypothesized value of 0.

• No, since the confidence interval does not include the hypothesized value of 0.

d. Interpret the results at αα = 0.05.

• We conclude that population mean 1 is greater than population mean 2.

• We cannot conclude that population mean 1 is greater than population mean 2.

• We conclude that the population means differ.

• We cannot conclude that the population means differ.

An object with total mass m_total = 6.3 kg is sitting at rest when it explodes into two pieces. The two pieces, after the explosion, have masses of m and 3m. During the explosion, the pieces are given a total energy of E = 44 J.

1)What is the speed of the smaller piece after the collision? (m/s)

2)What is the speed of the larger piece after the collision? (m/s)

3)If the explosion lasted for a time t = 0.028 s, what was the average force on the larger piece? (N)

4)What is the magnitude of the change in momentum of the smaller piece? (kg-m/s)

5)What is the magnitude of the velocity of the center of mass of the pieces after the collision? (m/s)

This is JAVA. Must write a short description of this program, usually a sentence or two will be sufficient. All the classes, methods and data fields should be clearly documented (commented).

Write a program that will predict the size of a population of organisms. The program should ask for the starting number of organisms, their average daily population increase (as a percentage), and the number of days they will multiply. For example, a population might begin with two organisms, have an average daily increase of 50 percent (=0.5), and will be allowed to multiply for seven days. The program should use a loop to display the size of the population for each day.

Input Validation: Do not accept a number less than 2 for the starting size of the population. Do not accept a negative number for average daily population increase. Do not accept a number less than 1 for the number of days they will multiply.

Example Run

Enter the starting number organisms: 2
Enter the daily increase: 0.5
Enter the number of days the organisms will multiply: 7

The active ingredient in a zinc nutritional supplement is ZnSO4·7H2O (molar mass = 287.58 g/mol). Ten zinc tablets containing a mix of the active ingredient and an inactive filler were ground and mixed together thoroughly. The total mass of these ten tablets was 10.165 g. A 1.830 g sample of the finely ground tablets was dissolved in an acidic solution. The solution was neutralized with ammonia and subsequently warmed in a water bath. Addition of (NH4)3PO4 to the solution resulted in the precipitation of ZnNH4PO4. The precipitate was filtered and dried, then ignited to produce 0.234 g of Zn2P2O7 (molar mass = 304.76 g/mol). What is the mass percent of ZnSO4·7H2O in each tablet?

2-What is the average mass of the active ingredient ZnSO4·7H2O and inactive filler in each tablet?

I need to second part (2)?

PHYTON QUESTIONS

Your assignment is to write the following magic methods for the Date class.

1. __eq__ returns True if two Date objects have the same month, day, and year.

2. __add__ is passed an int as a parameter, and adds that number of days to the Date. It is nondestructive. For example:

>>> d = Date(1,31,2017)

>>> d + 5 Date(2,5,2017)

>>> d Date(1,31,2017)

3. __getitem__ is passed either an int between 0 and 2, or a str ‘month’, ‘day’, or ‘year’. It returns the appropriate instance variable from the Date object, or raises an exception otherwise. For example:

>>> d = Date(2,1,2017)

>>> d[0] 2

>>> d[2] 2017

>>> d[‘day’] 1

>>> d[4] # should raise an IndexError

4. __setitem__ is passed an index (as described in problem 4) and an integer, and sets the month, day, or year of the Date object to be that integer. If the index is not of the correct type or value, then an exception is raised. For example:

>>> d = Date(2,1,2017)

>>> d[0] = 5

>>> d Date(5,1,2017)

>>> d[‘year’] = 2020

>>> d Date(5,1,2020)

>>> d[‘moth’] = 31 # should raise an IndexError

5. __radd__ is passed an integer, and modifies the Date object to be the specified number of days into the future. It is destructive. For example:

>>> d = Date(2,1,2017)

>>> d += 28

>>> d Date(3,1,2017)

in Java:

A point in the x - y plane is represented by its x-coordinate and y-coordinate. Design a class, pointType, that can store and process a point in the x - y plane. You should then perform operations on a point, such as :

– Print the point

– Set the x-coordinate

– Set the y-coordinate

– Get the x-coordinate

– Get the y-coordinate

– Add() : add two points

– Sub(): subtract two points

– Mul(): multiply two points

– Div(): divide one point from the other

– Ass(): assign one point to the other

– Equ(): check if two points are equal

– LessThan(): check if one point is less than the other • Note: R = √ X2 − Y2

– The default constructor

– The second constructor

– The copy constructor 2.

## Design a class pointTypeTest to test the design of pointType.
