I would say that Design and Measurement was my least favorite unit, there's just so much stuffs to do to come up with the answers. We really have to understand what the questions are asking from us before we start answering them, the same with the Sequences unit, we also have to read the questions carefully. Sometimes I get confused on making the formulas that we have to put in our calculator.
I hope our tests are short and not confusing. Good Luck on the test and the upcoming provincial and final exam...~(_8^(])

SequEnceS

We started our class with this 3 questions...
There are 2 different ways to find the answers for these questions.
For the first question, you add 3 to 5 to get 8, and then add 3 to 8 to get 11, and so on till you get the 110th term, but no one wants to do that. Here's the easier way...
On your calculator, press the "y=" button, (Make sure that your calculator is on "Seq" mode or "Sequence Mode".)
Your screen should look like this...Then enter...Then hit 2nd, Mode to exit to your main screen. Then enter u(110) (to enter u, press 2nd, 7 ) Press enter to get the 110th term which is 332.

For Question 2 you multiply every number by 2 to get the next number, continue till you get the 21st term. To use your calculator, go back to your "y=" screen. Clear everything up except the nMin=1.

Then enter...
Now, go back to your main screen and enter u(21), then hit enter to get the 21st term which is 3145728.

For the 3rd question, add the 1st and 2nd number to get the 3rd number, then add the 2nd and 3rd number to get the 4th number, and so on. This sequence is called the "Fibonacci sequence" where each number is the sum of the two preceding numbers.
To use your calculator, go to your "y=" screen. Clear everything up except the nMin=1.

Then enter...Go back to your main screen and enter u(27), then hit enter to get the 27th term which is 196418.

Then we moved on to another question...On this question we are now looking for the "term".
To answer this question without your calculator, Multiply each number by 2, then add 1 to the product. Do this until you end up with an answer of 1535.
But to use your calculator, go to your "y=" screen.

Then enter...
Then hit 2nd, Graph to get to the table. Scroll down till you end up with 1535.
So the term of 1535 in the sequence is 10.

This is the end of my scribe post... The next scribe is Kristel. ~(_8^(])

What I think about our unit Periodic Functions is that it's not so difficult compared to Probability and Statistics. I think that "DABC" is really important to remember on answering questions on this unit. We always have to start at D, or else we might get lost. The group works helped improve my understanding about periodic functions and I think I'm ready to take the test tomorrow.
Good Luck to everyone... ~(_8^(])

Personal Finance is almost finished. I really learned a lot of things from this unit that I could use in the real world. It helped me understand many things I didn't knew before, like the difference between leasing and buying a car, and mortgage. I also learned how to retire a millionaire...
Well, our 2 questions test is today, I just hope it's not too long and confusing...Good Luck! ~(_8^(])

Personal Finance

Hello everyone! Today we started our new unit Personal Finance. When we came to class, Mr.K immediately divided the class into 3 groups, then we looked at some Developing Expert Voices projects posted in our DEV website.
The first thing we learned on this new unit was the formula:

Mr.K also taught us how to use our calculator program TVM Solver, and then we used what we've learned on some practice questions.

To get to your TVM Solver program in your calculator, Press APPS(Applications), then press enter on Finance, and then enter on TVM Solver.
Our Homework for tonight is page 158, numbers 1-7.

FIN.... The next scribe is Chris A. ~(_8(])

I almost forgot to do my BOB... I think that our unit Vector was not as hard as our past units. We just have to understand the questions and keep our work clean and easy to read so we don't get confused. The only part that I get confuse sometimes is drawing the angle, like the 18 degree West of South. But I think I'm ready to take the test today. Good Luck everyone! ~(_8(])

I think that our unit Statistics is a hard and confusing unit, because of the different calculator commands that we have to learn how to use. But some part of it was easy to understand and use on problems, like finding the 95% confidence interval and the margin of error. What I think about our pre-test this morning is that it was short but confusing, I didn't even get the answer for the last page questions. If our test is tommorow, I really have to study tonight... and I'm gonna start now. ~(_8(])

ProbabilitY

Friday, March 9

Hey everyone, in our Friday's class, we started out with a 20 minutes pre-test for our upcoming Probability Test on Tuesday.
After the pre-test, the class was separated into 4 groups for us to share and discuss our answers to our group members.
Then we were asked to hand in one test paper per group with all the group members name on it.
Right after that, Mr.K. showed us the correct answers on the Smart Board.

Here is one of the questions we had on our test:

5 a...



and here is 5 b,c, and d...



To see the four other questions we did, please refer to the slides from March 9.
That's it for me... the next scribe is... jOweLL

As I expected, this Probability unit is alot harder than our first unit, Matrices, and alot more confusing. When we were given a question, it was hard to think of ways or solutions to answer them. It was hard to choose which of the different solutions we learned do we have to use to come up with an answer for a certain question or event. I think that the Smart Board really helps my understanding of what we are doing, not only that we could write our solutions on it, but also Mr. K could publish everything we wrote on it into our site, and we could review them at home.
I'm still not sure if I am ready for the test, but our pre-test tommorow will give me an idea on what to expect on the real test. ~(_8(])

PROBABILITY

In todays class, we started our new unit Probability, but Mr.K was not there, so we had Mr. Harrison as our substitute teacher. We were told to read pages 4-9 of our book, and assigned to do page 10, #s 1-9.

Probability
> If an experiment has x equally likely outcomes of which y outcomes are favourable to event A, then the probability of event A is: P(A)= x/y.

Here is one example of questions we did on class (#8).
>On the game board shown below, you can move the game piece diagonally forward.


















a) Determine the number of different pathways from the game piece to each of the squares on the other side of the board.


>There are 28 pathways to A.


>There are 34 pathways to B.


>There are 21 pathways to C.


>There are 6 pathways to D.





b) Assume that a player is equally likely to go left or right on each move.
What is the probability he will land on:
i) square A? ii) square C?

ANSWER:
Total number of pathways to exits= 28 + 34 + 21 + 6 = 89
i) 28/89 = .315 ii) 21/89 = .236

Our Matrix unit is almost over, and I feel confident going to our test tommorow. We started this unit by just adding and subtracting matrices, then we went on multiplying them. When we got to Transition Matrix, I didn't know what was going on because I was gone for three days and the topic was really confusing. But by doing some class works and group works I was able to catch up on our lesson.

Tommorow afternoon will be our test because we do not have class with mr.K in the morning.
Good luck on the test!
