E Price  
a) Identify the price point ranges for each product type for business to consumer and for business to business.
Create a table to summarize the products (services) and the price points.
It could be bronze, silver, gold or small, medium, and large etc for different product types coffee, tea, brownies etc or TV's, phones etc. If the service is free to consumers explain why? How does the company make money? What is the price they charge to businesses for the different services? Discuss if some services are provided free to consumers and if the service can be upgraded for a fee that might suggest a Good, Better, Best pricing strategy.

b) Discuss why or why not you feel their strategy is penetration pricing or skimming.  
c) Discuss if they segmented the market by price or some other segmentation approach.

Here is assignment 11 and it must be completed and submitted by Sunday july 26 at 11:59pm Pacific Time. Start early and follow the instructions. Please note, no late assignment will be accepted. The assignment’s grade will be available in your Gradebook by the following Tuesday.

This assignment is mainly to practice Selection programming structure with creating a project in VB. That is IF ... THEN ... ELSE ... END IF and  IF ... THEN ... ELSEIF ... ELSEIF .... END IF

1. Provide pics
2. Create a form with two labels, one textbox and one button, similar to sample form below. We use textbox control to receive input.
3. Here are the properties of the form and each control:
4. Form: change the title of the form to: Selection Homework – your name
5. Label1, Text: Enter a value for IntNumber; Name: lblIntNumber
6. Label2, Text: Display IntNumber; Name: lblResult ; BorderStyle: Fixed 3D; AutoSize: False
7. Textbox, Name: txtEnterIntNumber
8. Button, Text: Compute; Name: btnCompute

9. Double-click on Compute Button; declare variables you need to store entered intNumber and calculated intNumber. Both variables data type is Integer . Then type the Selection structure code from Assignment 7 #3. Run the program and test it for intNumber values of 50, 500 and 1000. For each test the result should be: 100, 500, and 3000 respectively.

Screenshots for creating a new project in VB:

1. When you open Visual Studio 2019 you see the following window, to create a new project in VB, click on "Create a new project" on the right:

2. In the next screen, Create a new project, you choose the correct project template. Since you created a VB project in Week 4, then the correct template: "VB Windows Forms App (.NET Framework)" will display in Recent Project Templates list, you will see a similar screenshot below, Just make sure you open VB Windows Forms App (.NET Framework) and not the one for C++. Click on Next button to continue:

3. Type project name: yourlastname-firstname-SelectionVBProgram in Project and select the VB folder that you will save VB project files in Location box. NOTE: your VB project will be saved in a folder with the project name you type in Project Name box. This will create a folder and a file with SLN extension. Both have the same project name. see below screenshot for where you enter Project name and Location:

4. To change the Location, click on three dots (...), locate the CS3 folder you created earlier for this class. in Project Location window, you should see VB folder that you created earlier in this assignment. Click once to select VB folder(do not double-click) and then click on Select Folder button. This will take you back to "Configure your new project" window. See below screenshot for selecting VB folder. Note that if you have selected VB folder to save the first VB Project, then it will automatically becomes the default folder. You will see the above screenshot. Click on Create to continue to VB Editor window.

5. Upon clicking on Create, you will be placed in VB editor window, see below:

6. From here on, click on View menu to activate Toolbox menu, expand Common Controls, Then add two Label controls, one TextBox and one Button controls on the form. Follow the instructions to name each control and add necessary text properties for each control. See below:

7. Then double-click on the Button which now should read “computer” to see the VB coding area, Form1.vb. type the code for the criteria in #9 such that when the program runs, you enter 50 for intNumber (textbox) and in the Label2 you see 100 displays, when you enter 500, result is 500 and when you enter 1000, the result is 3000. You have code in assignment 7.

Assignment 7 #3 Use the following selection structure to answer the next three questions:

If intNumber<= 100 Then

intNumber = intNumber * 2

ElseIf

    intNumber> 500 Then

    intNumber = intNumber * 3

End If

1. Assume intNumber initially contains 1000. What value intNumber will contain after the above selection structure is executed?

1. File input.txt contains 100,000 numbers separated by new line. Do the following:
   1. Write a C++ program to compute the summation of these 100,000 numbers using single thread.
   2. Write a C++ program to compute the summation of these 100,000 numbers using 10 threads, meaning each thread compute 10,000 summations and the main thread sum the result of the 10 threads.
   3. Using the time syscall to compare the time spent for 1.1 and 1.2

Turn Ins:

Source code of two programs and a short report on to answer the following question:

1. What is the run time for 1.1?
2. What is the run time for 1.2?
3. Is there a run time difference and why?

Nowadays, movies can be rented from a vending machine located at the entrance to many stores.  Suppose that it is now Friday evening at 8pm and a certain machine within a certain store has six copiesof the movie “Twilight” available for rent.  The machine will not be visited by the owner until Sunday afternoon at noon (which is 40hrs later), at which time returned movies will be restocked.

Suppose that customers wanting to rent “Twilight” arrive at this rental machine at a rate of 1 every 5 hours.

LetW= the time (in hours) until the next “Twilight” renter arrives at the machine.

Name the distribution of Wand identify the parameter.

Distribution name:  ___________________

Parameter value:  ___________________

What is the chance the next “Twilight” renter arrives sometime on Saturday?

      Thus, we seek the P( ___ < W< ___ ) which equals ________________?

LetX= the number of renters wanting “Twilight” that come to the

vending machine over the weekend (Fri 8pm until Sunday noon).

Name the distribution of Xand identify the parameter.

Distribution name:  ___________________

Parameter value:  ___________________

What is the probability that exactly 4 copies of “Twilight” are rented over

       the weekend?  Thus, we seek the P(X= 4) which equals ________________?

What is the probability that all copies of “Twilight” are rented over the

      weekend?  Thus, we seek  P( X __  __ ) which equals ________________?

• Q3 Problem description

Tim was born in a leap year, so he would like to know when he could have his birthday party. Could you tell him? Given a positive integers Y indicating the starting year, and a positive integer N, your task is to tell the N-th leap year from year Y. Note: if year Y is a leap year, then the 1st leap year is year Y.

• Input & output requirements

The input contains several test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow. Each test case contains two positive integers Y and N(1<=N<=10000). For each test case, you should output the Nth leap year from year Y.
