Mobile and wireless devices are being increasingly used in the Business Administration and Management Industry.   write a three-page paper that discusses three (3) mobile apps that could be used in business management. How do these apps increase the productivity of business managers and their customers? Are there any drawbacks involved in using these apps?

Your paper should include:

1. A three-page discussion of the problem.

2. A conclusion and list of all academic references used.

What are the options that might be considered in relation to introducing flexible work practices? What are any barriers to change and the pros and cons of possible changes?

Question 2 : Aggregate Scores: Write a program that opens 2 files, quiz.txt, and hw.txt. The program will
read each file and aggregate these values into the associated class variables. Using a list of Students, the
program keeps track of each student's scores. The program will then write out to the scores.txt file, the
students score in homework, quizzes, and their overall score. Related input files.
Each student is supposed to have 3 quiz scores and 3 homework scores. If a score is not present in the file,
then it defaults to 0 points.
Files will be formatted as a Name followed by a tab followed by a score.
Note: Refer to the Pre-Lab for the student class, and how to work with classes.
How to Calculate Grades:
Homework Percent can thus be calculated as:
Homework_Points/3
Quiz Percent can be calculated in the same way:
Quiz_Points/3
Student’s overall score will be computed using the following formula
HW_Score_Percent * .5 + Quiz_Score_Percent * .5
These scores work as each assignment is out of 100. Thus the homework percent is calculated as
hw_percent = student.HW/300 * 100, which equals hw_percent = student.HW/3
Required Design Schematic:
You must use the Student class. You must use a list of students. You must not use global variables.
● Write a function find_student(student_list, name)
o Either returns a student or an index to the student in the list
o Should return None if a student with name is not found
● Write a function get_HW_Scores(file_name, student_list)
o Opens the file
o Reads the file
▪ Divide the line into a name and score
▪ Finds the student
▪ Adds the score to the students homework score
o Closes the file
● Write a function get_Quiz_Scores (file_name, student_list)
o Opens the file
o Reads the file
▪ Divide the line into a name and score
▪ Finds the student
▪ Adds the score to the students quiz score
o Closes the file
● Write a function assign_grade(score)
o Returns a string containing a letter grade matching the percent, see the week 3 lab for scoring
brackets
o Feel free to copy your lab function for use here
● Write a function output_Scores(student_list)
o Opens the file scores.txt
o Loops over every student in the list
▪ Writes the students name + "\n"
▪ Writes "HW_Percent: " + str(hw_percent) + "% \n"
▪ Writes "Quiz_Percent: " + str(quiz_percent) + "% \n"
▪ Calculate num to be the overall score for the student
▪ Writes "Overall: " + str(num) + "%" "(" + assign_grade(num) + ")" + "\n"
o Closes the file
● Write a function main to call the above and other functions as needed to complete the task
Note: You are allowed to create as many helper functions as you need.

Define the term symbiosis specifically as it applies in a biological context. Compare and contrast parasitism, mutualism, and commensalism using a specific example of each type of symbiosis. For all three examples, explain how each organism in the relationship is affected.

A research team conducted a study showing that approximately 20% of all businessmen who wear ties wear them so tightly that they actually reduce blood flow to the brain, diminishing cerebral functions. At a board meeting of 20 businessmen, all of whom wear ties, what are the following probabilities? (Round your answers to three decimal places.)

(a) at least one tie is too tight


(b) more than two ties are too tight


(c) no tie is too tight


(d) at least 18 ties are not too tight

Research the internet for companies that have executed data science projects. Pick one company and describe a possible data science life cycle for that project. Make use of both information that you have researched as well as the information provided in the data science life cycle models.

Explain two theories or frameworks for understanding how Western Europe emerged out of 1,000 years of feudalism.

(e.g. 2-3 well-reasoned paragraphs).

Two cannons are mounted as shown in the drawing and rigged to fire simultaneously. They are used in a circus act in which two clowns serve as human cannonballs. The clowns are fired toward each other and collide at a height of 1.05 m above the muzzles of the cannons. Clown A is launched at θA = 76.0° angle, with a speed v0A = 9.50 m /s. The horizontal separation between the clowns as they leave the cannons is d = 5.55 m. Find the launch speed v0B and the launch angle θB (>45.0°) for clown B. magnitude m/s direction °.

What is the potential of a cell made up of Zn|Zn²⁺ and Cu|Cu²⁺ half-cells at 25^o C if [Zn²⁺] = 0.25 M and [Cu²⁺] = 0.15 M?

(Answer should be E = +1.09 V but I need to know how to get to that)
