Actions
(it’s a blog post by Annie Murphy) and then answer the questions below. This activity is one of the Discussions for your grade (see the grade goals in the syllabus (Links to an external site.)). Prompt
What is the main point of the Annie Murphy’s blog post: When and How to Let Learner’s Struggle? You should be able to state her main point in one short sentence!
From the reading, what are the three conditions that promote beneficial struggle?
How are the messages in the article and these Michael Jordan videos related to each other?
If you’re comfortable sharing, give an example in your own life where failure has been productive and actually contributed to your success. If you’re not comfortable sharing a personal example, share how you plan to address setbacks in this class so that they contribute to your success.

Read/Study eigenvalue notes from “Linear Algebra and Diff. Eqns. Using Matlab” by Golubitsky and Dellnitz.[2×2 matrices] [NxN matrices]
Write a summary of all important formulas and definitions from these eigenvalue notes.
Return a TWO page (typed) summary/review.
Suggested outline:
Leading ParagraphBrief description of main theme/goal of the paper and its relevance to science and/or industry. Make the reader become interested and motivate further reading with a thumbnail description of main results.For instance: “In this paper, the author(s) use geometrical techniques to explore the behavior of the logistic map. In particular, they show …
Technical SectionIntroduce mathematical models, if any. Briefly describe principal terms and summarize results of the analysis. If appropriate, break down the summary by cases, according to the layout of the paper.
Final CommentsProvide an objective overall evaluation of the paper. Constructive negative criticisms are valid, but not subjective remarks. What makes this paper interesting or bad from the scientific point of view?For instance, “…Although the authors make a significant effort in presenting graphical tools for the analysis of the model, the results that they provide are not novel …

PROVIDE A MATLAB CODE FOR THE FIGURES BELOW! with an image of the output that would be similar to the figure given! I will need about 3 new images
the instructions and figures are below!
I will provide the book in case needed

The annual fixed cost to make cupcakes is $18,000. The variable cost including ingredients and labor to make a cupcake is $0.90. The bakery sells cupcakes for $3.20 apiece.
a. If the bakery sells 12,000 cupcakes annually, determine the total cost, total revenue, and profit.
b. How many cupcakes will the bakery need to sell to break even?
Chapter 1 Problem 4
Evergreen Fertilizer Company produces fertilizer. The company’s fixed monthly cost is $25,000, and its variable cost per pound of fertilizer is $0.15. Evergreen sells the fertilizer for $0.40 per pound. Determine the monthly break-even volume for the company.

Problem 10
A large research hospital has accumulated statistical data on its patients for an extended period. Researchers have determined that patients who are smokers have an 18% chance of contracting a serious illness such as heart disease, cancer, or emphysema, whereas there is only a .06 probability that a nonsmoker will contract a serious illness. From hospital records, the researchers know that 23% of all hospital patients are smokers, whereas 77% are nonsmokers. For planning purposes, the hospital physician staff would like to know the probability that a given patient is a smoker if the patient has a serious illness.
Problem 12
The Senate consists of 100 senators, of whom 34 are Republicans and 66 are Democrats. A bill to increase defense appropriations is before the Senate. Thirty-five percent of the Democrats and 70% of the Republicans favor the bill. The bill needs a simple majority to pass. Using a probability tree, determine the probability that the bill will pass.
Problem 14
A metropolitan school system consists of three districts—north, south, and central. The north district contains 25% of all students, the south district contains 40%, and the central district contains 35%. A minimum-competency test was given to all students; 10% of the north district students failed, 15% of the south district students failed, and 5% of the central district students failed.
a. Develop a probability tree showing all marginal, conditional, and joint probabilities.
b. Develop a joint probability table.
c. What is the probability that a student selected at random failed the test?

Do a little research to find a statistician/mathematician who worked or currently works in the area you chose in the first question above. Include the following information about the statistician/mathematician. (Hint: in the past students have used social media or Google to find a statistician/mathematician who works, or worked, in the student’s chosen area.)
Source (Your instructor should be able to easily use your source to find the same information.)
Name of the statistician/mathematician
If available, embed a picture of the statistician/mathematician . Please do not attach the picture! Also, if available, you may copy-and-paste a link to a YouTube video of (or about) the statistician/mathematician.
A brief biography/description of the statistician/mathematician (In this assignment only, it is acceptable to copy the biography/description, but be sure to indicate that it is not your writing and give credit to the original source.)
Stuck on this question? Be sure to use the Discussion Board above to ask your classmates what they are doing to answer this question.

Hi, i want to learn how I can set up the Modwet ? I have a class after 12 hour and it should be setuped in my computer before the class. But i want the video for how i setup the modwet. and I need a simplified video because I’m not familiar with the MATLA

The ancient civilizations used different number bases. Which base system do you think was most effective? Why do you think they chose the base systems that they did? If you could choose any base for us to use in our society which would it be and why? Do we use any base systems today other than base 10? If so, tell us where and when.
