Explanation & Answer
This one is very simple. For any trapezoid with WX || YZ we know that
midsegment = 1/2(WX + YZ).
Thereby WX = 2*midsegment - YZ = 2*2.75 - 4.25 = 1.25 (centimeters).

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?

DirectionsFor this project, you will submit the Python script you used to make your calculations and a summary report explaining your findings.Python Script: To complete the tasks listed below, open the Project Two Jupyter Notebook link in the Assignment Information module. Your project contains the NBA data set and a Jupyter Notebook with your Python scripts. In the notebook, you will find step-by-step instructions and code blocks that will help you complete the following tasks:Hypothesis tests for a population parameterHypothesis tests for a population meanHypothesis test for a population proportionHypothesis test for the difference between two population parametersHypothesis test for difference between two population meansSummary Report: Once you have completed all the steps in your Python script, you will create a summary report to present your findings. Use the provided template to create your report. You must complete each of the following sections:Introduction: Set the context for your scenario and the analyses you will be performing.Hypothesis tests for the population mean: Discuss all steps of the hypothesis tests and interpret your results.Hypothesis test for the population proportion: Discuss all steps of the hypothesis test and interpret your results.Hypothesis test for the difference between two population means: Discuss all steps of the hypothesis test and interpret your results.Conclusion: Summarize your findings and explain their practical implications.Please see RUBRIC attached.

John makes DVDs, Algebra Assignment Homework Help
John makes DVDs of his friend’s shows. He has realized that, because of his fixed costs, his average cost per DVD depends on the number of DVDs he produces. The cost of producing x DVDs is given by John wants to figure out how much to charge his friend for the DVDs without making a profit. How much should he charge for 100 DVDs in order to break even? What is the cost per DVD? Suppose John makes more than 100 DVDs for his friend. complete the table below showing his costs at different levels of production. Graph the function C(x) from 0 ≤ x ≤ 3000 . What happens to the cost per DVD? Why do you think this happens?
