Transformations

Translation- slide along a straight line
Rotation- turn about a fixed point
Reflection- mirror image

Know how to do and describe each of them
plot (-4, 6) on this grid. Sorry if the grid is too small.


(sorry i don't know how to put roman numerals sign)

(+,+) = Quadrant 1
(-,-)= Quadrant 3
(-,+)= Quadrant 2
(+,-)= Quandrant 4

Notes

Notes for June 6, 2011

Measures of Central Tendency
- a value that represents the center of the data set.
- can be mean, median, or mode

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

data set- 2, 3, 4, 5, 4, 5, 3, 4, 5, 6, 7, 5, 34, 3
arrange- 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 7, 34

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


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


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



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


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


Practice
Find the mean, median, mode, range and outliers
  1. 45, 2, 48, 40, 45
  2. 14, 15, 18, 98,
  3. 100, 45, 110, 100, 150

Math Review Exam Slide 22

Just to let you know the colours and the bold in my text might not show up so I'm sorry for that part. Because when I previewed it it didn't show any of that.

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.
