Discuss at least 3 pros and cons of net present value.

Are there situations where a manger would prefer to use IRR? If so, give 3 situations & Why?

In this section, you will carry out the following basic estimation and tests of differences using the provided SampleDataSet.xlsx:

Identify three continuous and three discrete variables and describe their distribution numerically (e.g., central tendency, spread) as well as graphically. Compare the results.
Using the variables selected, conduct all possible t-tests and chi-squared tests. Describe your findings.
In addition, discuss how data limitations (e.g., missing values, etc.) can affect the validity and reliability of statistical estimations and tests of differences. Be specific. Show your work using Microsoft Excel and import your work into a Microsoft Word document.

The Task
Which is bigger, The Big One or Oblivion?
Using differentiation find the difference between maximum and minimum heights for both the roller coasters.

The height of the Oblivion coaster can be determined for 10 seconds after the coaster comes out of a loop by this polynomial

Calculate maximum and minimum heights using differentiation then draw the graph (by hand)
Confirm the factors of the Oblivion Coaster using factor theorem.

The brochure for The Big One coaster says that the height of the coaster can be determined by this polynomial model for the first 10 seconds

Calculate maximum and minimum heights using differentiation then draw the graph (by hand)

Compare the underground areas using the Trapezium rule and then confirm the areas using definite integration.

When the requirements and design are completed for a project, the coding can begin. A good first step in development is to use the design to create a prototype, or proof of concept for the system. The prototype helps ensure the validity of the design and demonstrates that the basic concepts in the design will provide the desired solution. For this SLP assignment you will use your Design Document from the Case Study to guide the creation of a prototype for your integrated system.

Part 1 SLP Assignment Expectations
The Prototype should address the following requirements:

The prototype should match the overall design created in the Case Study assignment and should provide evidence that the intended design will work.
A basic visual interface to support navigation of the program and identify the future functionality of the application.
No subsystem functionality is required but stubs to connectivity points for subsystems should be identified and have the ability to perform basic functionality tests.
All code should be well-documented with comments.
The program should run without significant errors.
Include a document called operation.docxthat describes how to operate the application.
This document should provide sufficient information to allow the instructor to set up and operate the application.
Identify any external system requirements
Key parts of the application should be identified (i.e., tell the instructor where to find the important parts of the application).
This document should also provide a summary of how the prototype shows proof-of-concept for the project.
Include a section called STATUS with a summary of the current status of your project including problems encountered and how they will be addressed. Be sure to contact your instructor if you need help addressing any issues.
Part 2: SLP Assignment Overview
For this SLP assignment you will submit the Alpha version of your project. An alpha version of an application will have the major functionality operational but not fully completed. The purpose of the Alpha version is to ensure the major functional components of the application will work as intended. Your alpha version should have connections established to all outside components and internally developed functionality should be operational at a least a fundamental level.

Part 2 SLP Assignment Expectations
The Alpha version should address the following requirements:

The application should match the design created earlier in the course with the exception of any changes required to address problems or conform to a revised timeline.
All major functionality should be operational at least at a minimal level.
Connections to outside components should be functioning at a basic level to prove they will work for the final version of the application.
The visual interface should provide access to all major functions of the application.
There should be a demonstrable, functional connection to the required database for the project.
All code should be well-documented with comments.
The program should run without significant errors.
Include a document called operation.docxthat describes how to operate the application.
This document should provide sufficient information to allow the instructor to set up and operate the application.
Identify any external system requirements
Key parts of the application should be identified (i.e., tell the instructor where to find the important parts of the application and changes that have been made since the last submission).
Include a section called STATUS with a summary of the current status of your project including work performed since the last submission, problems encountered and how they will be addressed. Be sure to contact your instructor if you need help addressing any issues.
ZIP all required project files and documents together and submit for grading.

Post two screenshots: 1) of a website or mobile app that does not use feedback properly, thus creating confusion for the user about taking some action on the site (if possible, make the screenshot of the confusing situation), and 2) of a website or mobile app that uses feedback effectively (if possible, make the screenshot of the effective communication) to communicate the status of an action to the user. In roughly 150 words per screenshot, critique the feedback process and note the overall impact on information design for each.

Assessment is intended to test (i) students’ knowledge and understanding of project management concepts and issues and their application to professional practice in information systems (ii) students’ acquisition of project planning and management. Assessment consists of group coursework (groups of 3 to 5 and report of 5500-6000 words) based on a mixture of individual (40%) and team (60%) case-study analysis. It includes the production, interpretation and description of a series of diagrams based upon the techniques covered in the lectures. No additional credit will be given for over-length work. You are expected to keep within the word range specified above. Writing to a word limit is a key skill which is often required in the workplace and producing assignments to length provides useful practice. All overlength work will be looked at particularly critically for irrelevant material and unnecessary detail. Overlength pieces of work commonly reveal these weaknesses and may lose you marks.

Further details of the case-study forming the basis of the coursework, along with a list of specific deliverables will be presented at the end of the week 5 lecture session.

this is a group case study. in my part I need to write 1500 words. I choose xp(extreme programming).please write xp related in Case study. and what is advantage and disadvantage of xp. answer: whether xp will apply in this case study or not ? and explain why. I will upload case study. please check it.

In the novel, Emma, discuss how the author treats the theme of romantic love and marriage throughout the novel. What role does romantic love and marriage play in the novel? How does the protagonist’s view of romantic love and marriage correlate to her society’s view? Does Emma’s coming of age change her view of love and marriage during the course of the novel? If so, how? If not, why do you believe that to be true?
Compare and contrast the treatment of racism in the United Stated in the novels To Kill a Mockingbird and Brown Girl Dreaming. How is racism treated similarly? How is it treated differently? In what ways do you believe the author’s identity and experience (the author in context) shapes the treatment of racism in the novels?
In the novel Tuck Everlasting, how does the author use symbols to discuss and explain her theme of immortality? How do these symbols correlate to Winnie’s coming of age? Do these symbols prepare the reader for Winnie’s final decision on whether she should choose immortality?
Compare and contrast the coming of age of the protagonists in To Kill a Mockingbird and Tuck Everlasting. In what ways do these girls come of age similarly? How is their coming of age different? What role does family play in the coming of age of these two protagonists? What role does society play?
