Explanation & Answer
Thank you for the opportunity to help you with your question!
-----------------------------------------------------------------
Length = 2a + 5Width = 3
First expression is the area of the rectangle = length x width = 3(2a + 5)
Expand it using distributive property=> a(b + c) = ab + ac
3(2a + 5) = 3x2a + 3x5 = 6a + 15
is the second equivalent expression.
ANSWER: 3(2a + 5) and 6a + 15

Discussion Post Conditional Probability Business Statistics 150 words
Conditional ProbabilityIn §4.4 we are introduced to the concept of conditional probability. The notation P(A | B) denotes the probability of event A occurring given that we know event B has occurred. Now consider the Monty Hall Problem introduced in the following video:https://m.youtube.com/watch?v=4Lb-6rxZxx0After watching this video, we know that if we are given the option to switch doors that, probabilistically speaking, it is in our best interest to switch. Explain why this is the case using your knowledge of conditional probability"should be a minimum of 150 words 300 words max. If you use any source outside of your own thoughts, you should reference that source. Include solid grammar, punctuation, sentence structure, and spelling."

You will write a 2 page review/abstract/summary on an article from a peerreviewed scholarly journal. This is to assess your ability to select and summarize
the research of others, analyze and apply the research of others, and communicate

ANOVA, MANOVA, ANCOVA, Mann-Whitney, correlation, regression.
2. Read the article thoroughly.
3. Write a 2-page summary about the article following the given guidelines.
Guidelines:
1. Your review should include:
a. The question/problem being researched by the author
b. The experiment that will answer the question
c. How they collected data
d. Analysis of the data (Must identify the statistical test used)
e. Their conclusion or findings
2. Your review can be single spaced or double spaced in at least 11 pt font.
3. You should make a bibliography to list the article you chose and practice APA
format. NOTE: The APA Guidelines address specifically how the reference
page is title and how articles are provided! Note: It is not called Bibliography.
4. Graphs or visual representations are not needed for this assignment.
5. A title page is not required, but you may include one if you want to practice
APA style. If you have a title page, your submission is 4 pages. If you do not
have a title page, your submission is 3 pages. Do not go over. There are
