Just incase, but yeah , i dont like design and measurements. i think it was horrible lol , but i like Sequences. thats ok, because its all about patterns. i really hope i pass tho, im on a roll term so far. i think ?!?!. but yeha good luck everyone

BOB

This unit was ok, just got to redo some of the questions to remeber.It was easy to to learn.sorry but i perfer personal finance lol , i just love it.

Personal finance

Today ,at math class, we were spreaded in groups of three and four.

On the smart Board there were some practice questions
here they're:

Question #1
Q1


Question #2
Q2


Then Mr.k was explaining about Calculate the Effective Interest Rate.
He given us an example question.

Question#3
Q3

Then we talked about credit card , and how much money they take off.
When using a credit card, us it as money you have in your pocket,
don't us it when you dont have money. They take interest rates compound
daily,so we did a example.

Credit Card , interest rate 18.5%, say it was $1 we spent.
Credit Card example

Question#4
Q4


Yeah i put them in links because it was too big to see,and i have work in 10 mins!!

well that's all kids the next scribe would be Ivy

wow, test 2orrow, and only a month of school left.This unit makes you think alot ,but otherwise like mr.k had said they are all calculated the same way , and method.well i have to say good luck people , and don't worry i'm just as scary as you guyz.

BOB

Wow this unit is so hard, its like every question u do is like different.After the pre-test it hit me hard.Like i can only answer 30 percent of the question.Aleast the unit isn't hard as proability.But yeah im like freaking out on the test.I did my homework and reviewed some question ,but until the pretest its just different.

When this unit is pretty hard. I think this unit is the most diffcult of them all. You just have to do all of question to test your self. Remeber what Mr.K said Math is a science of patterns. Well thats all i have to say for blogger to blogger, back to studying. by3

Proability Review

Hey everyone its tennyson in the house.Ok left just start by talking about what we did during class.

In the morning we didn't do much,Mr.K was explaining the assignment that we had to due.Which was :
-4 math questions (can be anything that we learned)
-answer & explain solution.

This project has a flexable and resting time for the due date. It can be done anytime.But be smart about it because testes and exam can get in the way, so it's better to be done earlier.

also this project can be done in any unique way.We were talking about using audio,slides,screen videos,and more.....

In the afternoon, we got into practicing questions in groups.

here are the questions:
Design an experiment using the random number function of your calculator to determine the probability of passing a six- question multiple choice test if you guess all the answers. Each question has four answers,and one answer is correct in each case.How many simulations would seem reasonable? What is the experimental proability of getting at least 50% on the test?

That is our first solution:





That is our second solution:

The different answers we got in class:

One more thing remeber this question is asking for the "expermental prob."

answer what it askes you ,not what it doesn't ask.

The last question that we did is:

As your birthday approaches you are looking for ways to make money so you can buy a used car.Currently you earn $10 a week for doing chores around the house.

Your parents realize that you are trying to save up,and offer you the following deal. You can either be paid the $10, or you can pull two bills, and a $10 bill. For example, you might pull out a $1 bill followed by $5 bill,and earn only $6. Or you might pull out the $10 bill followed by a $5 bill and earn $15.

If you were given this option every week, what would be better for you to do i nthe long run? Is pulling tow bills from the paper bag a great way to make money? Be sure to give complete explanation of how you found your answer.

Here is the answer

If Calculate the total for the bag it in 10 weeks is $82
the total for $10 in 10 weeks is 100.

you're better off with $10

Well thats it guyz by3

Today in class we talked about different problems that can be solved,and different rules that apply.

If the question doesn't talk about telephones, then the First digit can't be a 0.

Example:
How many four-digit even number are there if the same digit cannot be used twice?



If the question talks about telephones then the first digit can be a 0.

Example:
2) The last part of your telephone number contain four digit how many such four-digit number there

10 * 10 * 10 * 10
__ __ __ __ = 10000

When the questions deal with Letters,In the rules , it can't be repeated nomatter what.

Example:

How many ways can the letters of the word FERMAT be arranged?

6 *5 *4*3*2*1

_ _ _ _ _ _ = 720

it can be display as 6!

Another faster way would be:

This way is called "Pick" Formula

nPr = n!/(n-r)!

n is the number of objects available to be arranged

r is the number of objects that are being arranged
6P6= 6!/(6-6)!= 6!/0!=720

When the question has the same letters, you would have to put them to together , because they can't be switch around, its impossible.

Example:

BOOK

4!/2! = 12

4!: is the numbers of letters.
2!: is the numbers of the same letters.

Remember when enter this question on the calculator you would have to be careful.

Example:

Putting this on calculator is correct:

11!/(2!4!4!)

Putting this on caluclator is incorrect:

11!/2!4!4!
