November 30 Post...24 Days 'til Christmas

Hope you all had fun on your two snow days!
Mr. Max brought Nemo Kleenexes...yay!
Mental Math...everyone's favorite thing on an unmonday Thursday
Then we looked at the wiki site...Mr. Max will check what you've done on Monday because of the snow days...so you have a few days to figure out what question you want to post...just make sure you check the site first to make sure your objective hasn't been posted yet...Also check out the posts by pbwiki so that you can play with the html codes, underlining, bolding, and boxing things...


NORMAL DISTRIBUTIONS
Calculating Percent Values Under the Normal Curve


3 ways
1. Spreadsheet Way
ex) "Chicken Moisture"

2. Calculator Way
**Today is last day for ShadeNorm...Now use normalcdf
Bring to screen normalcdf (2nd Vars, 2)
normalcdf (low real score (2), high real score (6), mean (3.8), sd (1.3))
or normalcdf (low z-score (-1.385), high z-score (1.692) )

z = x - mean z = x - mean
sd sd
= (2-3.8) = (6-3.8)
1.3 1.3
from = -1.385 to = 1.692
***Nice, neat, even, and good way without too much hassle

3. The Web Way
www.ronblond.com - Areas Under the Normal Curve Applet

**Note that on the site the following image notations apply**







***There will be a homework check tomorrow for the questions that we did last Tuesday...and question 2 on that new package of papers is due tomorrow at the beginning of class

Tomorrows scribe will be Infedros

SNOW DAY!

Ok, so today is a snow day, but I am the only one here. 'cept for Mr. Max, of course. Teachers must always come to school. Rain, sleet, or snow... or even in the event of an inservice. :-)

Today in math all we did was... well, all I did was Accelorated Math, and worked on my Wiki assignment. If you go to Mr. Max's blog, you will find that assignment there. Have fun with it. It's Math *sarcastic excitement*.I believe that is all for today.

And to make Mr. Max's day, Mr. Bredin is a funny guy. He let us watch The Chronicles of Narnia in English. Hurray.

Tomorrow's scribe will be one of two people: Jessica, or I will again make a post, as today may not nessecarily count. I will discuss this with both Mr. Max and Jessica, and perhaps I will see you all again later.

Later Days!

Probability Review

Ok, this class was spent reviewing and studying for the probability test tomorrow. Hopefully we have no crammers for the test. Cramming hurts.

Well, I took almost the exact notes from Mr. Max. So I will post them here.

6 bites for the test
Remember: Double Sided Note Sheet for Test

1. Vocabulary/Terminology
-experiment
-trial
-event
-fundamental counting principle
-ratio/percent/decimal/etc.
-sample space
-fractorial
-permutation
-combination
-sets
-set elements
-independent event
-dependent event
-mutually exclusive
-mutually inclusive
-"with/without replacement"

2. "Pathway Problems" following "Pascal's Triangle Rule"
Be aware of the "Dr. Office" phenomenon type questions
i.e. P(going though) or P(not going through)

3. F.C.P (FUNDAMENTAL COUNTING PRINCIPLE)
a) FACTORIAL NOTATION
n! = n (n-1) (n-2)..... 3x2x1
b) PERMUTATIONS
nPr = n!/(n-r)!
order does matter
n = number of possible selections
r = number selected at a time
context clues: combinations locks, passwords, codes,
(? no repeats), 'words'
For same n, r values permutation is a large number.
c) COMBINATIONS
nCr = n! / (n-r)! r!
order doesn't matter (hence divide by number of selections factorial)
context clues: poker hands, pizza toppings, commitees
For same n, r Combination is a small number.

4. MUTUALLY EXCLUSIVE OR MUTUALLY INCLUSIVE
This is the best way for me to show you how this one works.


5. INDEPENDANT/DEPENDANT EVENTS
Context clues: 'with/without replacement',
Mr. Max recommended the use of tree diagrams for these type of questions.
He quoteth, "...tree diagrams will be best friends."

6. COMPLEMENTRY EVENTS
summary
P (A) + P (A') = 1
P(A') = 1 - P(A)

Ok. That is about it. One more image to help you with the test for tomorrow.

And, as is the custom, one joke.

Teacher: "What is seven Q plus three Q?" Student: " Ten Q"Teacher: "You're Welcome."

November 9th

Today I'm starting off with a statement full of joy! Yay for LOTS of snow!!!

Mental math (I learned something and I'm not being sarcastic), then a homework check on the assignment we were given from yesterday.

We went over the questions and the answers, in case you missed them, are as follows:
1. 2/15 3. 1/10 5a. 325/1326 5b. 13/221 7. 5/9
9. 6/35 11. 23/66

It would be a good idea to do accelerated math between now and Tuesday's test because we most likely will be doing Personal Finance until then.

******BIG HINT*****
Mr. Max will put at least one of the even questions from the Independent/Dependent Events package on the test.

Try to do question # 7 from the Personal Finance package (the Coopers') on a spreadsheet or using TVM Solver before Mr. Max gets to it tomorrow.

To end this blog on a positive note...

Tomorrow's scribe will be Mystic. Enjoy!

See How Grumpy This Guy Looks?

kattie Nov.1

Well today! We had Mr. Gorchenski! ( I'm really sorry I don't know how to spell, but thank you to Linz that might be it!) We missed you Mr. Max. So basically we were told to do Accelerated math and Exercise #2, 1-11! we also got a booklet handout, I'd tell you what it was called but seeing as the one night I forget to bring my math home is the day I scribe! But hmm. I was going to try and find some useful sites! I'll try and add some stuff later hopefully I'm really sorry guys (failure as a blogger!) Oh and by the way I checked out Marsha's links on her blog and they seem really neat. Anyways it’s really early and I'm really tired so I'm going to pick Ashley to be the next blogger! Have fun Ash.
