Carl's car

Today was started off with doing possibly the LAST mental math for this semester!!!!

we corrected question 8 in the booklet.

a) Calculate Carl's monthly payment if she purchases the car and finances it over a period of 5 years.

$557.80

b) carl can lease the car for 375 a month ( including taxes) for a period of 48 months. After this time, the residual value of the car is 40% of the original purchase price of 31920. Calculate the total price including the down payment of 2000 and the lease payments to purchase the car at the end of the lease. Indicate your strategy.

$32768.00

using the spreadsheet found in the "stuff you can use on the folder" , "mortgage schedule 2"

House price: $300,000

down payment: 10%; $30,000

interest rate: 4.75%

amortization period: 25 year

Maila- Lease or buy?

Starting off with mental math again and then continued on to the math problem of Maila leasing or buying a car (Question 3... a-d). Then we talked about the advantages and disadvantages of leasing/buying. The assignment is Question 8 A and B.

Lease vs. Purchase w/ Stratigies

"There will never be a dance party in fifth block applied math." - Mr. Max

We bought/leased cars today with our TVM solvers and/or spreadsheets. The question we are supposed have done by the end of the class is question 3 (involving Maila) on the back side of the first page of the booklet we got yesterday (Personal Finance Review).

While Max kept talking I kept listening and ignored the actual question, so I didn't really get anything done (I don't really like all this stuff anyway).

A useful way to "solve" the purchase problem is to use the PMT function in excel.

I'll expand on everything soon, just need to have something posted.

Standard Deviation Test

Today we wrote the standard deviaton test.
"Standard Deviation is measuring "spread", closeness from the middle or average, and if every number is the same there is no deviation."

If you are studying for the exam everything you need to know about standard deviation is already on the blog... good luck.

Welcome back from the long weekend everybody!

We started off the class doing mental math.

Then we started learning about Personal Finance

Investing money:

-difference between Appreciate(worth more)and Depreciate(worth less).

-We discussed different ways to solve finance questions.

Ways to solve finance questions:

On the calculator:

1) APPS, enter, enter

OR

2) put in variables/exponents on the home screen

On Excel:

1)Enter variables, and drag down

OR

2) Use the "function of X"

3) If you search *Canada Financial Solver Applet*, you probably will find sites to put in values to get your answer. Feel free to put a link on the blog if you find one.

Above picture is part A of question 1 (if you see this, copy it down! You'll be half way done the homework!)

Homework assignment- Finish question 1 (parts a&b) on the *written answer* half of the page we got today.

Test review

TEST TOMORROW!!!!! We reviewed standered deviation questions from previous exams. The links can be found on the blog, if you want to review more.

Today we started out with Mr. Max going through the homework that was asked to be finished on monday. The questions were 3, 5 and 8 on our Statistics Review. After that we started something new... it was called Confidence Intervals. I will be posting some slides that deal with it.

Monday April 20th

There is a test Thursday on Statistics.

The 3 things we did today are:

1. Homework check from the questions on Friday


2. C.C.C! Video on Demand.

If you go to the school website, on the front page if you go to students there is a link to get to the site. you use your user name and password from logging in at school (the one you use to get on any computer in the school).

You put in a key word and can search what you want to look for.

The point is you can look up anything you need to learn about and there is probably a video on there.

Also all of these videos are download-able, so you can put it on your ipod or phone using itunes. Not gonna lie it is kinda cool and really helpful.


3. We also got a new hand out on Binomial Distributions.

We are to do Questions 1-12 for tomorrow. They are on the last page of the hand-out we got today.

At the beginning of class today Mr. Maks handed back our Vectors test finally. Then he gave us more questions to do. Three of them actually. #3, #5, #9, and #15. Then we got the rest of the class to do the questions.

April 17 09

Today in class we started off with mental math. After mental math we learned something new. It was called Grouped data. After that we had a homework check. We also had some homework to do for tomorrow. I'm not quit sure what the homework was.

Tuesday April 14th, 2009

Today is early dismissal! Yay! Today we didn't do mental math. We went straight into math, and talked about question two that was assigned for homework yesterday. We had till 2:40 to accoplish and understand the problem. After we figured out the problem and showed Mr. Max we understood how we reached the solution, we worked on questions 7, 8, and 12.

Tuesday, April 7th, 2009

Today we started with Mental Math and Mr. Maksymchuk told us about his problem spelling the word "one" or as he would put it "wun". After that we learned about greek writing and the symbols on our calculators. Mr. Maks then refered to yesterdays Bellsite map while talking about sample and population calculations. We learned about the words mode, median, mean and range. When all the talking was done we got handed a booklet and got assigned the first two questions.

Variability and Statistical Analysis

Hello Everybody! Welcome back from Spring Break!

Today in math we started by doing Mental Math.

We started the next Unit which is: Variability and Statistical Analysis.

We are leaning Standard Deviation.

We were then asked how many kms we live from the school, rounded to the nearest km.With this data we made a table in Excel, and we found out the mean distance is 16.5km. We then found the difference from the mean, and you were either positive or negative depending on if you lived inside or outside the mean area (positive if you are outside, negative if you were inside). We then found the mean differences squared, we found that all the numbers were positive.
We then found the sum of the differences squared, then we divided this number by how many people there were that gave data, then we found out the standard deviation.

Standard Deviation is measuring "spread", closeness from the middle or average, and if every number is the same there is no deviation.

To calculate Standard Deviation on your calculator you:

PUT THE DATA INTO A LIST, PRESS STAT, THEN CALC, THEN PRESS ENTER TO TAKE 1 VAR-STAT TO YOUR HOME SCREEN, THEN AT THE HOME SCREEN PRESS SECOND, THEN THE NUMBER DEPENDING ON YOUR WHAT NUMBER YOUR LIST IS, FOR EXAMPLE YOU DATA IS IN LIST ONE THEN PRESS SECOND, 1. L1 WILL APPEAR, PRESS ENTER.

There are 11 symbols we are supposed to look up for tomorrow. These are the symbols that appear when you enter a Standard Deviation equation into your calculator.
