7 West Math

While we are creating our presentations in the computer lab today, Mr. Harbeck’s students in Canada will be doing the same thing!  Here are your instructions so everything will go smoothly for us.

1. Log into Novell.  Your username is your first and last name.  Your password is your lunch number.
2. Open Geometer’s Sketchpad and insert a text box into the window.
3. Type an explanation of your conversion.  You can change the font, size, and color of your writing.  Make it large enough to fill the screen.
4. Select and copy your  work.
5. Open  PowerPoint and paste your work from Sketchpad into a blank slide.
6. Adjust the size so that it fills the slide.
7. Save the slide as a jpeg file into a place where you can find it.
8. Go back to Geometer’s Sketchpad and create a summary slide showing the price of your item in US and Canadian currency.
9. Repeat steps 4-7.
10. Open Bubbleshare and log in using the email alatoba@gmail.com.  The password is ilovemath.
11. Follow the instructions on the alatoba wiki.
12. Once your album is created, copy the number that is found in the url after the words “myalbum/”
13. Paste this code onto the page for your group under your group name.
    • Click on “Edit Page”
    • Highlight “Place Bubbleshare Here.”
    • Click on “Insert Plugin”
    • Choose “Photos” and then “Bubbleshare Slideshow.”
    • Paste the album number into the appropriate box.
14. You are done!

A dart is thrown at random at each of the dartboards below.

(I will try to upload the pictures later.  You should have them on your worksheet.)

a.  For each dartboard, what is the probability that a dart will land in a region marked A?  A region marked B?  A region marked C?

b.  For board 1, what is the probability that a dart will land in a region marked A or B?

c.  For board 2, what is the probability that a dart will not land in region C?

Same rules as number 3.

Tioko and Dione are using the spinners from the Making Purple game to play a two-person game.  They take turns spinning the two spinners.  If the colors on the two spinners make purple, Dione scores.  If they do not make purple, Tioko scores.  For this to be a fair game, how many points should Dione score when the spinners make purple, and how many points should Tioko score when they do not make purple?

Post your answer as a comment.  Same rules as number 3.

In the Gee Whiz Everyone Wins! television game show, members of the studio audience draw a block randomly from a bucket containing 2 red blocks, 1 yellow block, and 3 blue blocks.  If a blue block is drawn, the contestant wins $5.  If a red block is drawn, the contestant wins $10.  If the yellow block is drawn, the contestant wins $50.  The block is replaced after each draw.

a.  What is the probability of drawing each color?

b.  If 24 contestants draw a block from the bucket, how much money can the game show expect to pay out?

Today we began a mini-unit on compound probability called What Do You Expect? We are exploring what happens when you find the probability of two things happening together. For example, if you flip a coin five times, what is the probability of getting heads all five times? This is much more complicated than finding the probability of getting heads on one flip. We will also be working from the textbook. There was no homework tonight.
