Hello Paul, hope you are doing well. You agreed to help me with my practice final which will be on May 24th, from 6pm-8pm (New York time), I hope you are still available to help. I am officially posting this question now ahead of time which will hopefully make it easier for us to interact and both of us to prepare, as I may have some questions for you while I study, I hope that is OK with you. My final is on the 29th, so that gives me four days to prepare after the practice final. As before I only need you to answer the questions I provide one by one, and a copy of your work for each question at the end of the assessment. The final will be on sections 2.2-5.5 from the textbook Single Variable Calculus, Early Transcendentals by James Stewart,8th ed Cengage Learning ISBN:9781305270336. The practice will be very similar to the official, so if you could offer advice on what to focus on in terms of studying and reviewing after helping me with it, I would greatly appreciate it. Let me know if there is anything you need.

will have four questions similar to the practice, please write details step so I can easy understand

given practice question and lectures

will send solutions to the practice tomorrow

For learning exercises 30.5. Do 3,4 and 5 . You can do 3 and 4 by using technology. It is a lot easier. Do not do by hand. For learning exercises 30.6 do 2 , 11, and 12. I will send you our class material. It might help you.

instructions: Homework 1 needs to be completed using RMarkdown please read through the other materials to help you answer the questions for the homework. Pls save the RMarkdown file as a pdf when you are done! The second part of the homework is a journal. Journals are to encourage responsible consumption of statistics “in the wild” and understand how methodologies might be used in various settings, we will be reading or viewing news articles, podcasts, videos, etc. This content comes from a variety of nationally recognized and credible news outlets and will be posted on Moodle. Your journal entries should be written in response to this content.Journal entries will be worth 15 points each. I will post questions to help guide your responses. To receive full points for your journal, you must engage with the material beyond simply answering the questions–for instance, how does the article clarify topics we’ve learned in class? How did it affect you? Do you have personal connections to any of the material? Did this article make you rethink your own position or habits? I have chosen to do option 1 for the journal please follow the instructions mentioned aboved for the journal entry i also have attached the article for option 1 that you will need to read in order to do the assignment. Please send the homework assignment as a pdf from RMarkdown and the journal entry as a word document these should not be saved all in one document thanks!

This activity requires the use of the Survey Data Set. Access by Clicking on the Class Survey Data File icon on the Home Page. You must download the file to edit, copy, and use the data. You must use your sdsu.edu account to access the class survey data file.

Below are 3 files: follow the Directions (1) to complete the assignment using the Survey Data Set (see above) along with the Descriptive Statistics Calculator (2), and then upload and submit your work using the Assignment Submission Form (3) via the appropriate link —

The assignment is due Tuesday, September 7, 2021 at 4:00 pm. There is a 24-hour window to submit late submissions for partial credit, after which this assignment closes.

If you are unfamiliar with Excel Charts and Pivot Tables, click on the Previous Arrow at the bottom of this page and view Additional Materials: Reference Videos for Competing A1-Ch2.

This being the first assignment, here is is 120 second video showing an assignment being copied & pasted into the submission form. All Excel sheets are protected but do allow for inputting data where needed and copying. There is a static slide at the end of the video with the directions for snipping (rather than copying) and Paste Special, both of which I mention in the video

There are 3 parts from A, B, C, D and I need help on part B-D

I need to know if the answer I got below are right?

Leave a comment below if you need help

=======================================================

part A:

0.1A + 0.07B

A+ 1 B <= 10000

A<= 6000

B>=2000

A>=B

======================================

part B:

I think it could be one of these below

“Correct answer is not listed”

, [“(0,10000) , (0,2000) , (6000,2000) , (6000,4000)”],

==========================

Part C:

(6000,4000)

=============================

Part D:

$880

========================================

(Here is the option for each answer for part A to D)

A woman has up to $10000 to invest. Her broker suggests investing in two bonds: Bond A, and Bond B. Bond A is a rather risky bond with an annual yield of 10% and bond B is a rather safe bond with an annual yield of 7%. After some consideration, she decides to invest at most $6000 in bond A , and invest at least $2000 in bond B. Moreover, she wants to invest at least as much in bond A as in bond B. She wishes to maximize her annual yield.

a) In each blank box below, select the best answer from the list that helps complete the objective function and its associated constraint inequalities.

Please note that the option <= indicates ≤ , and the option >= indicates ≥.

R=
[“0.07”, “6000”, “0.1”, “10000”,
“2000”, “Correct answer is not listed”] A+ [“Correct
answer is not listed”, “10000”, “2000”,
“0.1”, “6000”, “0.07”] B

A+
[“Correct answer is not listed”, “2”, “1”,
“0.07”, “0.01”, “2000”,
“6000”] B
[“<=”, “>=”, “=”, “Correct answer is
not listed”] 10000

A
[“Correct answer is not listed”, “<=”, “=”,
“>=”] 6000

B
[“Correct answer is not listed”, “<=”,
“>=”, “=”] 2000

A [“Correct
answer is not listed”, “<=”, “>=”,
“=”] B

b) Use
the geometric approach (with A placed on the x-axis and B on the y-axis) to
determine the coordinates of the corner points of the solution region. Then,
select the answer from this list:

[“(6000,4000) , (6000,2000)
, (8000,2000)”],

[“(0,0) , (0,10000) ,
(10000,0)”],

“Correct answer is not
listed”

, [“(0,10000) , (0,2000) ,
(6000,2000) , (6000,4000)”],

[“(6000,0) , (6000,2000) ,
(8000,2000) , (10000,0)”],

[“(0,0) , (0,2000) ,
(6000,2000) , (6000,0)”],

[“(6000,0) , (6000,4000) ,
(10000,0)”]

c) Which of the feasible corner
points you selected in part (b) above maximizes the objective function? Note that
a feasible corner point is any corner point with at least one non-zero
coordinate. Select the answer from this list:

[“(6000,0)”,

“Correct answer is not
listed”,

“(8000,2000)”

, “(6000,4000)”,

“(0,10000)”,

“(6000,2000)”,

“(10000,0)”]

d) What
is the maximum yield?

“$740”,

“$840”,

“Correct answer is not
listed”,

“$700”,

“$800”,

“$920”,

“$880”
