Why or why?

Survey & Graph Project Part 2 This assignment is the second part of a two-part assignment in which you practice the first three steps of the statistics process: 1) Asking a research question, 2) collecting data, and 3) describing the data. Directions For your written assignment, you should do the following: Give your survey to individuals to answer. If in Part 1 you said that you In your assignment, please include the answers to these questions: 1.Briefly describe your surveying experience: What obstacles did you face — if any — as you gave out your survey? Did you get all the responses you wanted? Why or why? Did you change your sampling method? Please explain. 2.Construct a table that has the following (use the table in Example 2 on page 64 as a model): 3.Frequency distribution 4.Relative frequency distribution 5.Construct 2 bar graphs of the following (use the bar graphs in Example 3 on page 65 as a model): 6.Frequency distribution 7.Relative frequency distribution 8.What conclusions can you come to? In other words, what do think your data is telling you? 9.What is the answer to your research question? I have already written part 1 several weeks ago and I copy paste part 1 that you could see,I attached files there was bar graphs in pages,you should use them for part 2

Explain why the process of finding the domain of a radical function with an even index is different from the process when the index is odd.

Select two questions from the following list:
Explain what is meant by the nth root of a number.
Explain the difference of finding the nth root of a number when the index is even compared to when the index is odd.
Show two different algebraic methods to simplify 4^(3/2). Explain all your steps.
Explain when a radical expression is in simplest form.
Explain what is meant by the word rationalize in the phrase, “rationalize a denominator.”
Explain how to find the domain of a fourth root function.
Explain why the process of finding the domain of a radical function with an even index is different from the process when the index is odd.
Explain how dividing complex numbers is similar to rationalizing a denominator.
2. Prepare the solution to the selected exercise showing the solution on a step-by-step basis. If your response is a descriiption of a process, concept, or problem-solving technique then be sure to show at least one example to support your post.
3. Check the solution if possible.
4. Discuss the method of solving the exercise that was used and possible real-world applications that could be solved with the same technique.NEED TO USE THE REFERENCE PROVIDED IN ATTACHMENT PLEASE.

1) the differences between digital signatures and electronic signatures.

Write a research paper on digital signatures and certifying authorities including their relation to RSA Public and Private Key encryption. This research paper should be at least 800 – 1100 words and include references to the legal status in developed nations, the mathematics behind the technology, what are the major recognized authorities, and the likely future for this technology/business practice. The researcher should find the major US entities and how they relate and trust each other. On the legal topic, the researcher should find national and state laws and standards. You may also find laws from other countries and international organizations. Since many of these laws are now a decade or more old, we could also find legal interpretations of the law itself.
For this project, complete some basic research on the trust infrastructure of the internet. This research should include Digital Signatures, Certify Authorities, Public Key Infrastructure, RSA, and the laws that support these entities. Be sure to include the following relationships:
1) The differences between digital signatures and electronic signatures.
2) Identify a digital signature and how it might be better than a holographic signature (good old pen on paper).
3) Describe Certifying Authorities, identifying who they are and the whole PKI (Public Key Infrastructure).
4) Describe some of the laws that make this technology legally binding.
5) Discuss some of the math behind RSA/Public Key Cryptography.
In researching this topic, I hope that you can provide a clear explanation of how all this works to provide security, authentication, and non-repudiation in the online environment. This topic becomes more and more relevant every day as we do more and more business and live more and more of our lives online.
Please cite two or more authoritative sources. Government sources are a good source for the legal aspects of trust on the Internet. Reputable vendors (the companies that operate some of these services) often have good resources on how these entities work. Finally, research and industry standards organizations are also excellent sources.

Research on diophantine equations.

Diophantus was a great mathematician who studied and wrote about problems with two or more unknowns where the solutions were limited to whole numbers. An example of a Diophantine problem is: “If twice Betty’s age in years plus Joe’s age in years equals seven, how old are Betty and Joe?” Solve this problem, and then explain why it falls into the category of Diophantine equations.
He researches the Diophantine equations in-depth and uses the information he gathers to help present these types of problems to a group of students.
Prepare a lesson plan for grade 5 of elementary, the duration of the lesson, the materials, the objective, the standard, the vocabulary, the procedure (step by step), the evaluation, the activity for printing to each student, and the extension. Be sure to include a comprehensive self-assessment of the lesson.
