//Objective: Write programs that use the random number generator.//



Get into your Gaggle digital locker and save your RandomNumber.frm program to your desktop.

Write the answers on paper and keep it for later in the period when you write your own program.

1. When you run your RandomNumber.frm program, do you get the same exact results as the example shown on the direction sheet?

2. Why or why not?

3. What line in the code makes cmdOne produce a **decimal**?

4. What line in the code makes cmdTen produce a **decimal**?

5. What line in the code makes cmdFive produce an **integer**?

6. What line in the code makes cmd100 produce an **integer**?

7. What line of code guarantees that the results will be truly random?

8. What is the keyword in Visual Basic that produces a random number between 0 and 1?

9. What type of numbers exist between 0 and 1?

10. When you multiply a number between 0 and 1 by 10, how many digits are to the left of the decimal point?


 * Study the code and the output from several tries before answer these questions.**

11. Describe the number that will be stored in memory in **LessTen** because of this line of code in **cmdTen**. **LessTen = 10 * Rnd **

12. Describe the number that will be stored in the variable, **UpTo5**, because of this line of code in **cmdFive**. **UpTo5 = 5 * Rnd **

13. What must **Rnd** be multiplied by to produce a number from 1 to 33?

14. Write the line of code that will put a random number from 1 to 33 in the variable, **UpTo33**.

15. True or False: To have a program user pick the highest number, use a textbox to get the number and multiply **Rnd** by the numerical variable where that number is stored.

16. Write the assignment statement for putting the random integer from 0 to the top number the user provided, into a variable in memory, if these declarations are given? Dim Top As Integer Dim UpToTop As Integer

Study the RandomNumber.frm **code** and its **output** first. Use your answers that you put on paper from the Do Now. Make sure to type your **name** in the name box on the left before you start the quiz. After you are finished, read the corrections and the explanations that go with them. Even if you got all the answers correct, please read the explanations that are provided below the problem. If you did not get 100%, take it again. Follow this link. Random Numbers with Rnd » quiz Program: **MyRandom.frm** Refer to the questions in the Do Now, your answers on paper, and the quiz explanations to help you with the program.
 * Correct your answers on your lined paper so you have that to refer to when you do your own program.!!**

 Turn in your paper with your name, period and 16 corrected answers on it.

//Objective: Write a program that uses the random number generator to produces random numbers within a certain range.//

__Paper and Pencil:__ 1. Use a random number generator online @http://www.random.org/integers/ or @http://www.psychicscience.org/random.aspx to pick the number of the ticket that you are hypothetically being given from the range pictured to the right (410005 to 410514). Write down your ticket number. 2. Use a random number generator online to pick the 5 door prize winners' numbers picked from the tickets distributed which had a range of numbers from 410005 to 410514. Write down the ticket numbers. 3. Did you win a door prize? 4. Ticket numbers 410005 through 410514 were distributed. How many tickets were distributed? 5. Write the chance of winning a door prize as a fraction. 6. Write the chance of winning as a percentage.

Program: **RandomNumber.frm** Directions can be found in your binder.

 __Paper and Pencil/Fill-in-the-Blank:__ 7. In Visual Basic, a random decimal number between 0 and 1 is generated with the use of the keyword, Rnd **.**

//Objective: Discover why a program to calculate slope needs an If Then Else structure.// //Objective (Eligible Content M11C3): Relate slope to parallelism.//
 * Friday November 19, 2010**



Draw an x y coordinate system on a piece of graph paper. Plot these pairs of points and draw a line through each pair. (3, 6) (-2, 6) (5, -3) (2, 8) (10, -5) (10, 3) (-5, -9) (5, 9) Calculate the slope of each line and write it next to the line. Write the word horizontal by the horizontal line. Write the word vertical by the vertical line. Draw a line that is parallel to one of the lines and use two points on the line to determine its slope. What can you conclude about parallel lines and slope?

Study the SlopeLine.frm directions and explanation in your notebook. Discuss with the student next to you as necessary.

__Paper and Pencil:__ 1. When typing a fraction into VB, what must surround the numerator of a fraction that has more than one thing in it? 2. When typing a fraction into VB, what must surround the denominator of a fraction that has more than one thing in it? 3. The slope of a line can be calculated by using the coordinates of two points on the line. The slope is the difference in the y direction divided by the difference in the x direction. Write the assignment statement for the formula for slope of the line that contains the points, (xone, yone) and (xtwo, ytwo).
