Divisibility Rules

Divisibility~Means when a number can be divided by another number, with no remainder or decimal.

Its a whole number.

Divisibility Rules

0 ~ 0 can't go into anything.

1 ~ 1 goes into all numbers.

2 ~ if the number is even.

3 ~ the sum of the digits have a multiple of 3. In your review it says sum of the digits is 3, so make sure you know.

4 ~ if you can divide the number twice by two and still have a whole number.

5~ if the number ends in 0 or 5

6 ~ if 2 and 3 can go into the number.

8 ~ if you can divide the number thrice by 2 and get a whole number.

9 ~ sum of the digits is nine.

10~ ends in 0

Try practicing your divisibility rules by finding out which one of the divisibility rules go into these numbers.

June 6th Notes

Measures Of Central Tendency
-a value that represents the centre of a data set
-can be the mean, median, or mode
-data set is a group of numbers that you must arrange in order from least to greatest
eg. 2, 3, 4, 5, 6, 5, 4, 5, 3, 4, 5, 6, 7, 5, 34, 3 (not organized)
2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 7, 34 (organized)

• Median- the middle number in a set of data after the data have been arranged in order

eg. median of 2, 5, 6, 8, 9 is 6

• Mode- the most frequently occurring number in a set of data

-mode and most both have 4 letters (a way to remember)
-mode of 3, 5, 7, 7, 9 is 7
-mode of 2, 2, 4, 6, 6, 8, 11, is 2 and 6 (can have more than 1 mode)

• Mean- a measure of central tendency

- the sum of a set of values divided by the number of values in the set
-mean of 6, 4, 8 is 6 (6+4+8= 18/3= 6)
-add up all the numbers, divide by how many numbers there are

• Range- the positive differences between the largest and smallest values in a data set

-range of 1, 3, 4, 5, 5, 6, 6, 8, 8, 9 is 8 (9-1= 8)
-range of -7, -4, -2, -1 is 6 (-1) - (-7)= 6

• Outlier- a value that is much larger or smaller than the other data value

-the data set may have more than 1 outlier or zero outliers
-outliers for 1, 64, 65, 67, 67, 68, 100 are 1 and 100

Divisible- means when a number can be divided by another number, with no remainder or decimal. It should be a whole number.


Always remember when you're adding and subtracting fractions, you should always simplify (put it into lowest terms)

4.)71.08 ÷ 12.04=

Math Exam Review Slide 23

Adding and Subtracting Fractions
















So the question is 1/2+1/2 = 2/2, but that isn't good enough because you have to always simplify when it can be simplified. So its 1/1 then 1 whole. First you always check for common denominators. If your fractions have the same denominator you leave them the same and just add the numerators.

Subtracting















The question was 3/4 - 1/4=2/4=1/2. ( make sure you don't forget to simplify.) First you check for common denominators. In this question they are the same so just take away the two numerators.

Try these questions to help you practice :).

2/3+4/5=
6/7+2/8=
2/3-1/3=
4/5- 2/5=

Answers...

1. the common denominator is 15. So whatever you did to get 15 u do to the numerators. So 2x5=10 so its 10/3, then 4x3= 12 so its 12/5. So 10+12 = 22 and the denominators stay at 15. Its 22/15. Now you have to simplify it to 1 whole and 7/15.

Since I already told you how to do this I'm just gonna give you the answers now.

2. 1 whole and 3 /28

3.1/3

4. 2/5

Measures of Central Tendency

Measures of Central Tendency- A value that represents the center of a data set.

3 types of data set - Mean,Median&Mode

Data set is a group of numbers that you must arrange in order from least to greatest.

Median- the middle number in a set of data, after the data have been arranged in order

How to get the median (Eliminate one from the left,eliminate one from the right)

Mode- the most frequently occurring number in a set of data

Mean - measure of central tendency. The sum of a set of values divided by the number of of values in the set.(add up all the numbers, divide that number by how many numbers there are)

Range- the positive difference between the largest to smallest values in a data set

Outlier- a value that is much larger or smaller than the other data value

Notes for June 06, 2011

Measure of Central Tendency- a value that represents the centre of a data set.

- can be the mean, medi

an and mode.

Data set- is a group of numbers that you mus

t arrange in order from least to greatest.

e.i 2,4,3,5,3,4,5,5,6,4,5,3,7,34,5,6

arrange from least to greatest: 2,3,3,3,4,4,4,5,5,5,5,5,6,6,7,34

Note: Before you find the Median, Me

an or Mode be sure that you arranged it from least to greatest.

Median- the middle number in a set of data after the data have been arranged in order.

If you left with two numbers you need to add them and divide them to get the median.

e.i

Mode- the most frequently occurring number in a set of data.

- mode and most have both 4 letters.

e.i

mode of 3,5,7,7,9 is 7 because 7 appeare

d the most.

mode of 1,1,1,2,2,2,3,3,3,4 is 1,2 and 3 because they appeared the most.

mode of 1,1,1,2,2,2,3,3,3 is no mode b

ecause they`re all last or second place.

Mean- a measure of central tendency.

- the sum of a set of values divided by the number of values in a set.

Range- the positive differences between the largest and smallest values in a data set.

Outlier- a value that is much larger or smaller than the other data value.

- the data set may have more than 1 outlier or zero outlier.

e.i

1,67,68,64,65,100 are 1 and 100 because the rest of them starts with 6 except for 1 and 100.

Here`s our homework for those who did not write it.

Find mean, median, mode, range and outliers.

18,19,79,17,20,12

14,14,16,15,16

98,202,99,91,2,95,89,88,94

Here`s a link to help you practice for mean, median, mode, range and outliers.

I also found a video to help you understand all about our lesson.

I hope this little information help you! :D

Math Notes

Measures of central Tendency
- A value that represents the centre of a data set
-It can be Mean, Medium or Mode
-A data set is a group of numbers that you must arrange in order from least to greatest.



Median- the middle number in a set of data after the data have been arranged in order


If this^ happens, all you have yo do is find out what number is in between the two numbers. So take 6 and 8, You know that 7 is in between so, 7 is our median. Another way to find out the median...
Take the two middle numbers (6 and 8) add them together (6+8) and that would equal 14 right? So, you take 14, and divide it by 2 (14÷2) and that would equal 7, and seven (7) is our Median.


If this^ happens, remember the first thing you do when you get a data, you have to arrange them from least to greatest, after you do that and you get two numbers in the middle and you wanted to find out the Median, remember: take the two middle numbers (3 and 10) add them together (3+10) and that would equal 13 right? So, you take 13, and divide it bye 2 (13÷2) and that would equal 13, and thirteen (13) is our Median.

Mode- the most frequent occuring in a set of data. Here is how you can remember the meaning, MODE and MOST have both 4 letters and they both start in "MO".

(e.g) 3,5,7,7,9
the Mode would be "7" because it's the most occuring number, there are two of them and only one the other numbers.
(e.g) 2,2,4,6,6,8,11
the Mode would be 2 and 6, because there are two and them and they are both tied for having two numbers.
(e.g) 1,1,1,2,2,2,3,3,3
the Mode is nothing because there are three of them for each number.
(e.g) 1,1,1,2,2,2,3,3,3,4
If this happens, the mode this time would be 1,2 and 3, because they are all tied for being first.

Mean- A measure of central tendency. Th sum of a set of values divided by the number of values in the set.





The Mean in this^ image is 6, because the data states 4, 6, and 8, So you take all the numbers in the data (4, 6, and 8) and then add them up (4+6+8) and then that would equal 18 right? So, take 18 and divide it by how much numbers there are in the data, In this data there are 3 numbers, (18÷3) and that would equal to 6, So 6 is our Mean.


Range- The positive difference between the largest and smallest values in a data set.

If this^ happens, always remember when you get a data set, you have to order them from least to greatest, after you do that you take the biggest number (in this situation it's #9) and the smallest number (in this situation it's the #1) and subtract the biggest number to the smallest number (9-1=8) and that would equal to 8, so 8 is our Range.

Outlier- A value that is much longer or smaller than the other data value, the data set may have more than 1 outlier or zero outliers.

The outliers for 1,67,68,67,64,65,100 would be 1 and 100, because the rest of the numbers are somewhere in the 60's and 1 and 100 are so far off.

2j x 3= 36

Variable-(j is the variable)  a letter that represent a unknown number.

Expression-(2j x 3) any single number or variable or a combination of operations.

Constant-(3 is the constant) a number that does not change, increases or decreases, the value of an expression.

Numerical coefficient-(2 is the numerical coefficient) a number that multiply a variable.


Equation- mathematical statement with two expression that have the same value. (a scale)

eg. x+3=3 , y-7=(4) , 3a-2=a+2 , b=4






Identify the value of variable.

 Isolate the variable:

Use opposite operation:

Add - Subtract
Subtract - Add
Multiply - Divide
Divide - Multiply


Remember, when did something on the left side you have to do the same thing in the right side.
 

 

Remember to always check your answer.

HOW TO ISOLATE A VARIABLE

Math notes for June 2, 2011

Practice: Show every step... then check

A+4=10
6+4=10
10=10

Use reverse order of operation, what you do the first one, you have to do to the other. (As you can see when we used reverse order of operation the first time, we also did the same at the end)

Here are some other practices we did:

CHECK:
B-2=5
7-2=5
5=5


CHECK:
3c=21
3x7=21
c=7


CHECK:
2j+1=9
2(4)+1=9
8+1=9
9=9


CHECK:
f÷3-2=1
9÷3-2=1
3-2=1
1=1
