Explanation & Answer
Thank you for the opportunity to help you with your question!
14+3x=4x
The goal is to get all the x's on one side, and all the constants on the other.
To do so, subtract 3x from both sides
14+3x-3x=4x-3x
14=1x
or x=14

Article Analysis 2
Search the GCU Library and find two new health care articles that use quantitative research. Do not use articles from a previous assignment, or articles that appear in the Topic Materials or textbook.Complete an article analysis for each using the "Article Analysis: Part 2" template.Refer to the "Patient Preference and Satisfaction in Hospital-at-Home and Usual Hospital Care for COPD Exacerbations: Results of a Randomised Controlled Trial," in conjunction with the "Article Analysis Example 2," for an example of an article analysis.While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

Discussion: Multiple Regression
This Discussion assists in solidifying your understanding of statistical testing by engaging in some data analysis. This week you will work with a real, secondary dataset to construct a research question, estimate a multiple regression model, and interpret the results.
Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will post your response to the hypothesis test, along with the results. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another.
To prepare for this Discussion:
Review this week’s Learning Resources and media program related to multiple regression.
Create a research question using the General Social Survey that can be answered by multiple regression.
Use SPSS to answer the research question. Post your response to the following:
What is your research question?
What is the null hypothesis for your question?
What research design would align with this question?
What dependent variable was used and how is it measured?
What independent variable is used and how is it measured?
What other variables were added to the multiple regression models as controls?
What is the justification for adding the variables?
If you found significance, what is the strength of the effect?
Explain your results for a lay audience, explain what the answer to your research question.
Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.
Respond to at least one of your colleagues’ posts and comment on the following:
Do you think the variables are appropriately used? Why or why not?
Does the addition of the control variables make sense to you? Why or why not?
Does the analysis answer the research question? Be sure and provide constructive and helpful comments for possible improvement.
If there was a significant effect, comments on the strength and its meaningfulness.
As a lay reader, were you able to understand the results and their implications? Why or why not?

TUTA SPSS Computation and Interpretation Questions
Homework 8 focuses on the application of concepts addressed in Exercises 19 and 35. This homework uses data from a randomized prospective study by LePage and colleagues (2017). A sample of 111 veterans with a history of homelessness and mental illness were randomly assigned to either an experimental treatment condition involving a specialized vocational program, or treatment as usual services at a veterans affairs health center. One of the study outcomes was obtaining stable employment post-treatment (in other words, the rate of stable employment).The two variables in this example are dichotomous: Group (Experimental Program versus Treatment as Usual {TAU}) and having obtaining stable employment post-treatment (yes/no). These data are presented in HW8.sav. The null hypothesis is “There is no difference between the experimental and TAU veterans on achieving stable employment post-treatment.”Questions to be answered in word Doc Open in SPSS. Use the dataset to answer the following questions.The study data are presented in HW8.sav. The contingency table is below:Stable EmploymentNo Stable EmploymentExperimental Group1017Treatment As Usual (TAU)777Compute the chi-square. List the numerator.List the denominator.Using the numbers in the contingency table, calculate the percentage of veterans in the Experimental Group who achieved stable employment.Using the numbers in the contingency table, calculate the percentage of veterans in the TAU Group who achieved stable employment.Write your interpretation of the results, as you would in an APA-formatted journal.

MTH109 Pepperdine University Traveling Salesman Problem Paper
Traveling Salesman ProblemFor this Critical Thinking assignment, you will
solve a real-world optimization problem using graph theory.Part I: Complete the following steps:
Select a
real-world optimization problem that is an example of the Traveling
Salesman Problem (TSP).
Create a graph modeling the
real-world scenario corresponding to the problem. Use weights to represent
the variable that you are optimizing.
Find an optimal solution for the
problem using the concepts studied in this module.
Part II: Based on your work in Part I, discuss the following:
Discuss your
rationale for your choice of the real-world optimization problem. How were
you able to identify that it was an example of the TSP? Why is this
example relevant?
Describe how you created the
graph modeling the real-world scenario corresponding to the problem.
Determine if the graph is
complete. If so, use your graph to describe the formula for computing the
number of Hamilton circuits.
Explain in detail how you solved
the problem.
Describe a method for finding a
non-optimal solution to the problem.
Consider another variable that
could be optimized in the problem. How would your answers to Part I be
affected by this change?
Discuss the advantages of using
graph theory to solve this problem.
Requirements:You must submit TWO files for this assignment.
The first file should contain the computations, graphs, diagrams, etc.,
associated with the questions in Part I. This file may be formatted as a
numbered list of answers. Unless stated in the problem, a narrative discussion
is not required, but you must provide enough information to show how you
arrived at the answer.The second file should be a 2-3-page narrative
paper, written in APA format, associated with the situation described in Part
II. Specific requirements for the paper are provided below:
