Explanation & Answer
4y^4(9x+5)^8-3y^3(9x+5)^7
(9x+5)^7[ 4y^4(9x+5)-3y^3]
(9x+5)^7[ y^3{4(9x+5)-3}]
(9x+5)^7[ y^3{36x+20-3}]
(9x+5)^7[ y^3{36x+17}]
(9x+5)^7 (y^3)(36x+17)
you can find the values of x and y by putting each factor equal to zero.....

Walden University Central Tendency & Variability GSS Dataset Discussion
For this Discussion, you will examine central tendency and variability based on two separate variables. You will also explore the implications for positive social change based on the results of the data.
To prepare for this Discussion:
Review this week’s Learning Resources and the Descriptive Statistics media program.
For additional support, review the Skill Builder: Visual Displays for Categorical Variables and the Skill Builder: Visual Displays for Continuous Variables, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.
Review the Chapter 4 of the Wagner text and the examples in the SPSS software related to central tendency and variability.
From the General Social Survey dataset found in this week’s Learning Resources, use the SPSS software and choose one continuous and one categorical variable Note: this dataset will be different from your Assignment dataset).
As you review, consider the implications for positive social change based on the results of your data.
Post, present, and report a descriptive analysis for your variables, specifically noting the following:
For your continuous variable:
Report the mean, median, and mode.
What might be the better measure for central tendency? (i.e., mean, median, or mode) and why?
Report the standard deviation.
How variable are the data?
How would you describe this data?
What sort of research question would this variable help answer that might inform social change?
Post the following information for your categorical variable:
A frequency distribution.
An appropriate measure of variation.
How variable are the data?
How would you describe this data?
What sort of research question would this variable help answer that might inform social change?
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.

MTH 156 Colorado State University Estimator New York Survey Data MCT 6 Report
Option #2: New York Survey DataA consulting firm was hired to conduct a survey on people living in
New York City. The survey was completed monthly for six months by 445
randomly-selected people in different boroughs. There were a number of
items on the survey, but six basic biographical items will be studied
for this exercise. The data for the people surveyed in one of these
monthly surveys can be found in the Excel file SURVEY. The variables that were used for the basic biographical data are found on the last page of the exercise.In this exercise, some of the estimation techniques presented in the
module will be applied to the New York survey results. You may assume
that these respondents represent a simple random sample of all potential
respondents within the community, and that the population is large
enough that application of the finite population correction would not
make an appreciable difference in the results.New York City governmental agency personnel like to have point
estimates regarding variables describing the biographical information of
the people living within the different boroughs. It is very helpful for
them to have some idea regarding the likely accuracy of these estimates
as well. Therein lies the benefit of the techniques presented in this
module and applied here.
Item A in the description of the data collection instrument lists
variables 1 through 5, which represent the respondent’s general attitude
toward each of the five boroughs. Each of these variables has
numerically equal distances between the possible responses, and for
purposes of analysis they may be considered to be of the interval scale
of measurement.
Determine the point estimate, and then construct the 95% confidence interval for μ1= the average attitude toward Manhattan.
Repeat part (a) for μ2 through μ5, the average attitudes toward Brooklyn, Queens, The Bronx and Staten Island, respectively.
Given the breakdown of responses for variable 6 (highest level of
education), determine the point estimate, and then construct the 95%
confidence interval for p6= the population proportion of doctoral degrees.
Given the breakdown of responses for variable 7 (marital status of
respondent), determine the point estimate, and then construct the 95%
confidence interval for p7 = the population proportion in the “single or other” category.
Assume the governmental agencies requested estimates of the mean
attitudes towards each borough with a margin of error of 0.05 for each
borough. If the governmental agency personnel want to have 95%
confidence that the sample mean will fall within this margin of error,
how large should the sample sizes be for each borough?
Requirements:
Your paper should be 2-3 pages in length (not counting the title
page and references page) and cite and integrate at least one credible
outside source. The CSU Global Library is a great place to find
resources. Your textbook is a credible resource.
Include a title page, introduction, body, conclusion, and a reference page.
The introduction should describe or summarize the topic or problem.
It might discuss the general applications of the topic or it might
introduce the unique terminology associated with the topic.
The body of your paper should address the questions posed in the
problem. Explain how you approached and answered the question or solved
the problem, and, for each question, show all steps involved. Be sure
this is in paragraph format, not numbered answers like a homework
assignment.
The conclusion should summarize your thoughts about what you have
determined from your analysis in completing the assignment. Nothing new
should be introduced in the conclusion that was not previously discussed
in the body paragraphs.
Include any tables of data or calculations, calculated values,
and/or graphs referenced in the paper. (Note: The minimum required
length excludes any tables or graphs.)
Document formatting, citations, and style should conform to the CSU Global Guide to Writing and APA Requirements (Links to an external site.). A short summary containing much that you need to know about paper formatting, citations, and references is contained in the Template Paper (Links to an external site.). In addition, information in the CSU Global Writing Center (Links to an external site.) has many helpful areas (Writing Tips, Template & Examples/Papers & Essays, Figures and Tables, and others).
NOTE: You MUST submit your Excel file with your
report. This will allow you to qualify for consideration for partial
credit if any errors are found in your report.
