Thank you for the opportunity to help you with your question!
The total height of the composite figure is h=(3*3) in.= 9 in.
surface area= (8*4*2)+(8*9*2)+(4*9*2). Note that we multiply by 2 in every part because there are 2 faces that are similar.
surface area= 64+ 144 + 72
surface area= 280 in.^2

MATH 225N Chamberlain College of Nursing Week 4 Probability Discussion
Probability plays a major role in the medical community. Diagnoses are based on probabilities. They are really questions or "what if's", and are answered by the probability that the treatment will be the best for the ailment.
Let's look at probability in terms of both the real world and the medical community.
Survey 30 people to find out if they are left-handed or right-handed, and use the following chart to create a contingency table with the information.
Left handed Right handed Total Female Male Total
Answer the following questions about the information in your contingency table:
If a person is randomly selected from the survey participants, what is the probability that the person will be left-handed?
If you randomly choose a female from the people you surveyed, what is the probability that she is left-handed?
What is the odds ratio of choosing a left-handed female?
What is the relative risk of choosing a left-handed female?

70 (A+C)

Probability of Green - (A+C)/(A+B+C+D): 70/130 = 0.54
Probability of Green Cat - A/(A+B): 40/60 = 0.67
Odds Ratio of Green Cat - (A/B)/(C/D) or AD/BC: (4040)/(2030) = 1600/600 = 2.67
Relative Risk of Green Cat - [A/(A+C)]/[B/(B+D)]: (40/70)/(20/60) = 1.71
Skim through at least one of the following articles on left-handed vs. right-handed people from the Chamberlain Library. Answer the following question: How do the probabilities and percentages for your study compare to those in the study you read?

MATH 534 KGS Wk 6 Regression & Correlation Simple Linear Regression Analysis Essay
Final Project: Regression and Correlation Analysis Use the dependent variable (labeled Y) and one of the
independent variables (labeled X1, X2, and X3) in the data file. Select
and use one independent variable throughout this analysis. Use Excel to
perform the regression and correlation analysis to answer the following.
The week 6 spreadsheet can be helpful in this work.Generate a scatterplot for the specified dependent variable (Y) and
the selected independent variable (X), including the graph of the "best
fit" line. Interpret.Determine the equation of the "best fit" line, which describes the
relationship between the dependent variable and the selected independent
variable.Determine the correlation coefficient. Interpret.Determine the coefficient of determination. Interpret.Test the utility of this regression model by completing a hypothesis
test of b=0 using α=0.10. Interpret results, including the p-value.Based on the findings in steps 1-5, analyze the ability of the independent variable to predict the dependent variable.Compute the confidence interval for b, using a 95% confidence level. Interpret this interval.Compute the 99% confidence interval for the dependent variable, for a
selected value of the independent variable. Each student can choose a
value to use for the independent variable (use same value in the next
step). Interpret this interval.Using the same chosen value for part (8), estimate the 99%
prediction interval for the dependent variable. Interpret this interval.What can be said about the value of the dependent variable for
values of the independent variable that are outside the range of the
sample values? Explain.Describe a business decision that could be made based on the results
of this analysis. In other words, how might the business operations
change based on these statistical results.All DeVry University policies are in effect, including the plagiarism policy.Final Project report is due by the end of Week 7.Final Project is worth 130 total points. See grading rubric below.Summarize your results from Steps 1-11 in a 3-page report.
The report should explain and interpret the results in ways that are
understandable to someone who does not know statistics.Submission: The Word document, summary report should be
submitted for questions 1-11. The Excel output can be included as an
appendix, if needed.Format for report:Summary ReportSteps 1-11 addressed with appropriate output, graphs and interpretations. Be sure to number each step 1-11.

SOCI 332 America Public University Week 7 Providing Poor Communities PPT
Take your Week 7 Final Portfolio Assignment and digest it in a presentation format. Create a narrated multimedia presentation using either Power Point, Screencast-o-matic (http://www.screencast-o-matic.com), or Prezi. Remember, narration with audio (not just ppt notes) is necessary. In essence, your presentations should "play" for us. The presentation should be no more than 5-10 minutes (about 8-10 slides). Be sure to provide some background on the topic, discuss your variables, provide figures (tables/charts - frequencies/graphs, crosstabs, tests of significance and measures of association), and conclude by highlighting how your research fits into the existing body of literature on this topic.*Minus the audio*
