Warm-up Day 1 Solving Inequalities and Graphing the Solution on a Number Line: 1) 2x – 6 ≤ 8 2) 4x + 1 > 13 3) 4 + 5x ≥ 19

2
Solution? 1) 2x – 6 ≤ 8

3
Solution? 2) 4x + 1 > 13

4
Solution? 3) 4 + 5x ≥ 19

5
Warm-Up Day 2 Set up a chart and graph the function: f(x) = 2x – 1

6
Warm-Up Day 3 No Warm-Up! Prepare for test. Sit quietly and review until tests are passed out.

7
Warm-Up Day 5

The Mean The "mean" is what we usually think of as an "average." The mean is simply the sum of all the scores in a group divided by the total number of scores. So, in our maze example:

9
The Median The median is another way to describe a set of numbers. The median is the score that is exactly midway in the set of numbers. The easiest way to find the median is to rank the numbers in order. If we rank the scores from the music group in the rat maze data, it would look like:

10
Mode The mode is a third way to describe a set of numbers. The mode is very easy to find; it is the number that occurs most often. For example in the set of numbers:

11
The Range The range is the difference between the highest value and the lowest value in a sample. For example, in the set of numbers: 2, 2, 2, 7, 8, 9, 10, 11, 11, 15, 20, the range is:
