1.Determine whether S spans V . Justify your answers.

V = C ^0 [−1, 1] (the vector space of continuous functions on [−1, 1]) and S = {1, t, t2 , t3 , . . . }.

2.Let S be a set in a vector space V and v any vector. Prove that span(S) = span(S ∪ {v}) if and only if v ∈ span(S).

The municipality of a major city in Quebec is planning to build a new bridge to decrease the traffic load on the existing bridges connecting both sides of the city across the river. Construction is to start in 2020 and is expected to take four years at a cost of $25 million per year. After construction is completed, the cost of operation and maintenance is expected to be $2.5 million for the first year and to increase by 2.8% per year thereafter. The scrap/salvage value of the bridge at the end of year 2053 is estimated to be $5 million. Consider the present to be the end of 2018/beginning of 2019 and the interest rate to be 8%.

a)   Draw a cash flow diagram for this project (from present till end of year 2053).
b)   Find the Present Worth of this project.
c)   Find the Future Worth of this project.

Students are to complete Module 4, Human Resources and Capacity (Scenario) in Practice Operations. Based on their observations in this scenario, and upon a careful review of the available literature, the student is to consider him - or herself to be the Production Manager of Kibby and Strand, the company in the scenario.

The CEO is thinking of expanding Kibby and Strand, and you are tasked to create a data collection plan and measurement criteria for how production output and product quality will be measured. Create your collection plan and output measurement criteria assuming the current production capacity in the simulation scenario will be doubled.

In addition, the HR manager asks for a list of qualifications and skill sets required for production shift managers to staff the expansion. Create your job ad to include qualifications and desired skill sets.

The student is to create the data collection plan, measurement criteria, job qualifications list, and staffing plan based on knowledge learned in the scenario, and post it in the discussion

QUESTION:

Add code so that if no parameter values are specified for method “main”, then the error message “file name expected” is printed out instead of the "Opening file " message. Hint: If no parameter values are specified for method “main”, then the length of the array “args” will be zero. If that error message “file name expected” is printed out, the program should stop. You can make any Java program stop using this line …

• System.exit(0);

1. Write a program to prompt the user to enter a first name, last name, student ID, number of hours completed and GPA for 5 students. Use a loop to accept the data listed below. Save the records in a text file.
2. Write a second program that reads the records from your new text file, then determines if the student qualifies for Dean’s list or probation. Display the records read from the file on screen with appropriate headings above the data being displayed. Save screenshot for submission.

If the GPA is >= 3.5, display 'Dean’s List'

If the GPA is < 2.0, display 'Dismissed’

If the GPA is < 3.5 and >= 2.0, display 'Regular Standing'

‘Online Educational Systems’ (Online) has developed a package to deliver integrated curriculum and face to face group learning, for all levels of students around the world, due to the Covid-19 pandemic. Online has asked you to research customer preferences and to recommend a pricing policy. There are limited price differences relating to the timing of classes in the Northern Hemisphere. However, for Southern Hemisphere classes running a class at or below 45 students (normal class size is 50) costs significantly more for Online to run the class.

a. In addition to customer preferences, what information would you like to gather before recommending a pricing policy? Explain why each item you list is relevant.

b. Explain why it is important to understand customer preferences before investing in the infrastructure to run the system.

c. Is the need to consider customer preferences different for this organisation than for another type of organisation? Why or why not?

Eight male and eight female college students who have credit cards were surveyed and asked their total credit card debt. The responses are given below in dollars:

1. Is this an observational study or a designed experiment? Explain your answer.

2. Is it reasonable to use Welch’s t-test? Explain your answer.

3. Is there a difference in the mean credit card debt of males and females? Use α = 0.10. List out all 5 steps in the hypothesis testing and show your work.

Step 1

Step 2

Step 3

Step 4

Step 5

4. Construct a 90% confidence interval for the difference in the mean credit card debt of male and female college students.
