I found this link to be very useful. There are links to quizzes and tests for every section of the textbook!

5-5 Fractions and Percent Ratio; a comparison of two numbers by division
 * Notes from 1-3-12**

34:100 34/100 34 out of 100 34 per 100 = 34%

When you compare a number to 100 it can be written as a %

8/20 8/20 = 40/100 = 40% (multiply both numerator and denominator by 5 to equal 100)

$18.95 out of 100 = 18.95%

percent as a fraction 78% = 78/100 = 39/50

46.5% = 46.5/100 = 465/1000 = 93/200

4-6 Functions and Linear equations
 * Notes from 11--30-11**

Function rule 2x 3---> 6 4--> 8 5--->10 6-> 12

The input, {3, 4, 5, 6} is called the domain The output is called the range {6, 8, 10, 12}

The domain represents the x values, and the output represents y values.

To graph this function, the ordered pairs are: (3, 6) (4, 8) (5, 10) (6, 12)

-7 + (-8) + + 4 -3 + 6 - (-7) + - 10 -2 + 8 Rule 1: Eliminate double signs -7-8+4-3+6+7-10-2+8 Rule 2: box negatives: -7-8-3-10-2 = -30 Circle Positives: 4+6+7+8 = 25

25-30 = -5

2-7 Bar Graphs and Histograms

Histogram = A special kind of bar graph. It used bars to represent the frequency of numerical data organized into intervals.



Zoo project due 10-21-11. You must do a box and whisker plot and bar graph. For third graph, choose between a steam and leaf plot, histogram, or line plot. Don't do a line graph- we aren't showing change over time!

**Notes from 9-30-11 ** ** I ** wrote the notes on the frequency tables worksheet that Mrs. Lawson handed out in class and uploaded them here.

Math: Abby, I scanned a copy of the 2-1 worksheet and emailed it to you. We can go over it in the learning lab tomorrow if you have questions. [|homework 2-1.pdf]I also uploaded it here. Let me know if it works!
