(Digitally highly preferred) Create an x-axis and y-axis on any paper, real or digital. Draw a side view of a simple roller coaster with at least two hills and one loop. Specify the x and y axes intervals in feet. Mark one point at the bottom and one point at the top of the first uphill. Select points for which you know the coordinates, and afterwards write the coordinates next to each labeled point. Remember it’s (x, y). Make a mark near the top of the first downhill and another near the bottom of the first downhill. Then do it again for the second downhill. Choose points for which you know the coordinates. Next to each point you just marked, write the coordinates. Make a note of the domain of your coaster. This is the domain of the whole coaster, not just the points you marked. Then, write down your coaster’s range. This is the total range of the coaster. Determine the slope between the two uphill points. Display your work. Calculate the equation for the line connecting these two uphill points using this slope. Simplify after using the point-slope form. Display your steps. Determine the slope (also known as the rate of change) between the two downhill points you marked. Then, on the second downhill, compute the slope between the two points you marked. Display your work. Determine which of the two downhills is steeper, and explain how you determined this based on their slopes. Determine whether the graph you created for this coaster qualifies as a function. Then explain why it is or is not a function. Review the function definition and the vertical line test for just a function.

This week we examine how to solve for an unknown quantity. Some situations may be easily modeled by single variable equations and others might be more difficult. Due Thursday Respond to the following in a minimum of 175 words: Reflect on your professional or personal world. What is an example of a situation that you might be able to use an equation with a single unknown to help understand? What is an example of a situation that you might not be able to use an equation with a single unknown to understand? What makes an equation with a single unknown helpful in one of your examples but not the other? What patterns exist in your two examples that might be helpful in determining when to use a simple equation?

This week we investigate how quantities exist in multiple dimensions (i.e., 2-dimensional and 3-dimensional space). Naturally, we think about the world in three dimensions because that is what we experience daily. As a result, our minds are frequently making qualitative inferences about the space around us. However, we may or may not naturally quantify those situations. Respond to the following in a minimum of 175 words: Reflect on your day today. Think about all the times you considered how much space something took up to help make a choice. List as many examples from the past 24 hours as you can recall. Which of those did you quantify (measure) before acting? In which cases might you have saved yourself some resources if you would have used what you are learning this week to quantify the situation? Due Monday- * *****THE RESPONSES ARE IN THE UPLOADED FILES> MUST RESPOND TO 2! Both responses must be 75 words or more.***** Post 2 replies to classmates or your faculty member. Be constructive and professional.

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

Will be sending the assignments as you finish the previous. There will be assignments, quizzes, and tests. 2 math culminating during January. Am willing to pay more.

1)The assignment consist in selecting your individual state of the US to work with( discuss this selection as first come first served in the group chat to avoid repretitions that are not permitted) 2) Collect real data from the elections department in that state about the historic popular vote for the candidates in every presidential election for that state of your selection( note that data can be copied and paste in minitab directly from an excel format, no need to type one by one) 3) Collect from the national election department the popular and the electoral votes of the candidates from every presidential election in the hisoiry of the country 4) Describe the characteristics of the popular vote in the state of your choice, with a formal and documented statistical report as explained in class, be creative, specific to your data and detailed using the strategy shown in class ( you may replay the meetings) 5 ) Explain the correlation and its significance between the popular vote from your state and the national outcome in popular votes 6) Explain the regression analysis and its significance between the popular vote from your state and the national outcome in popular votes 7) Produce a bar graph comparing the electoral vote and the popular vote in the last six presidential elections 2020 you may use in this point the features of excel if you find it convenient) 8) Produce your conclusion about the evidence you may find in that last bar graph for further use in categorical by-variate data
