Module 5 Practice Tests Chapters 10, 11 & 12

Q DB: Module 5 Practice Tests Chapters 10, 11 & 12: Post your Math questions from chapters 10, 11 & 12. You are required to post (at least) one question and its solution either from Chapters 10, 11 & 12 Practice Tests posted under the modules, or any source of your choice (per grading policy in the syllabus). You must read all the posts and make sure not to duplicate any questions; similar questions are acceptable. 1. Read all the posts: questions and solutions posted by others first, and pick a different question to post (No duplication is allowed). A question with One-word solution, One-line solution, or Definition is not acceptable and results in ZERO Points for the post . (10 points) 1. Write the question number and copy down the question 2. Show all steps using the math equation editor \(\sqrt{Math}\) (The above Math Palette): 2. Find a similar problem online, or on YouTube, or Khan Academy and post the link. (5 points) 3. Comment on (Explain) at least one classmate question that is either solved or is found online and posted by watching it carefully in its entirety. Explain about what the question addressed and what you learned from it and outline a few steps you learned as a result; a complement is nice but is not a comment. To receive credit for this part, write the name of your classmate. (5 points) Example of a Student Post (Made up example): 1. Question 15: Find the mean, median, mode, and range for the following Population list: 13, 18, 13, 14, 13, 16, 14, 21, 13 Solution: \(\mu=\frac{\sum x}{N}=\frac{13+18+13+14+13+16+14+21+13}{9\:}=9\) \(\text{The median is the middle value, so rank the data first: 13, 13, 13, 13, 14, 14, 16, 18, 21}\) \(\text{Population size: N = 9, so the middle value will be the (9 + 1) ÷ 2 = 10 ÷ 2 = 5th number:}\) 13, 13, 13, 13, 14, 14, 16, 18, 21 \(\Longrightarrow Median\:=14\) \(\text{The mode is the number that is repeated more often than any other: }\Longrightarrow Mode=13\) \(\:Range\:\:R=Max-Min=21-13=8\:\:\) 2.

Comment on question by John Doe’s YouTube post: This post was about finding the Z Scores; they represent number of standard deviations away from the mean. A positive Z-score indicates a score which is above the average score in class. A negative Z-score indicates a score which is below the average score in class. A zero Z-score indicates a score equal to the average score in class. https://www.youtube.com/watch?v=1yYCyAwg-7gLinks to an external site. Grades: A positive Z Score represents a grade greater than the mean (average) grade in class. A negative Z Score represents a grade smaller than the mean (average) grade in class. A zero Z Score represents a grade that is equal to the mean (average) grade in class. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Please refer to the following instructions for "How to Embed an Image in Canvas Discussion" for help.
