Stand Deviation and Range

Today we learnt....“The square root of the quotient between the sum of all x subtract x bar squared divded by n”.
We were shown how to calculate the standard deviation and range in a set of numbers.
Population Standard Deviation- the measure of variability within a data set.
Range- is also a measure of variability
We used kindergarten students and grad students as a sample.

Today we got a little distracted before we did mental math. Mr. Maxs confirmed he has a brother and showed us his house on google earth. We then looked up more things and got back on track to mental math. We are working on our exercises 3 and 4.

Stamps Game

Today we did notes on Pathways and practiced the first question ( with Jason and Penelope ). We took notes on F.C.P. and we were supposed to do Factorial Notation but were doing that tomorrow. One of Mr. Maxs examples was: Calculate the number of ways to enter and exit the arena during a hockey game.
a) first period
ways in= 1
ways out=5
Therefore there are 5 ways in and out of the building.
b) third period
ways in=5
ways out=5
Therefore there are 25 ways in and out of the building.

We did notes on pathways, and how many ways you can get to the dentist office. Then we got questions, excercise 1-6.

Today Mr.Max called us up to show him excercise 1-2. We also had to tell him a plan for our Vector projects. I am not too sure what I am going to do yet, but its due on the 27th. Today i'm just going to work on excercise 3.

Vectors Presentation

Due Date: Nov.27th
format negotaible, possibilities include:

*Start with a known RESULTANT vector!
- Must include: 5 specifically appropraite, context- based, scenarios that have as their answer, the resultant vetor. i.e. scenario #1 is......., scenario #2 is...., etc. Each scenario has to include a minimum of 2 vectors( magnitude and direction scaled and directed for each )

We did not do mental math today. We work on our questions are we must have excercise 1, 2 and one question on 3 complete for mondays class.
