Absolute Value?

ABSOLUTE VALUE IS HOW FAR A NUMBER IS FROM ZERO THE ABSOLUTE VALUE OF -9 IS 9. THINK OF ALL NUMBERS AS POSITIVES EVEN ZERO. I -7 I = 7MARKS SHOW YOU WANT TO ABSOLUTE VALUE DOESN'T MATTER WHICH WAY YOU SUBTRACT 8-3=5 ANDF 3-8=5 - I-12I = - 12 SINCE THE NEGATIVE IS OUTSIDE THE ABSOLUTE BRACKERS

A chart that use either horizontal or vertical bars to show comparisons among categories. One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value.

No skew

Center point is highest

pi, square root, e, golden ratio (cannot be written as a fraction)

Famous irrational numbers

It is similar to a Bar Chart, but a _____________ groups numbers into ranges And you decide what ranges to use!

Histogram

Change is something over time? What graph?

If you want to show a change in something over time, you would use a line plot.

Positive skew

Left side is higher

If you want to show a change in something over time, you would use a ___________________

Line plot

Rational numbers

Most numbers we use in everyday life are Rational Numbers. A Rational Number can be made by dividing two integers. (An integer is a number with no fractional part.)

12 / 6 × 3 / 2

Multiplication and Division rank equally, so just go left to right: First 12 / 6 = 2, then 2 × 3 = 6, then 6 / 2 = 3

3 + 6 × 2

Multiplication before Addition: First 6 × 2 = 12, then 3 + 12 = 15

Order of operation PEMDAS

P Parentheses first E Exponents (ie Powers and Square Roots, etc.) MD Multiplication and Division (left-to-right) AS Addition and Subtraction (left-to-right)

(3 + 6) × 2

Parentheses first: First (3 + 6) = 9, then 9 × 2 = 18

However, if the goal is to compare a given category (a slice of the pie) with the total (the whole pie) in a single chart and the multiple is close to 25 or 50 percent, then a _________________can often be more effective than a bar graph.

Pie chart

Perimeter of a quadrilateral

Quadrilateral Perimeter = a + b + c + d

Perimeter of rectangle

Rectangle Perimeter = 2 × (w + h) w = width h = height

Negative skew

Right side is higher

__________________show how much one variable is affected by another. The relationship between two variables is called their correlation.

Scatter plots

Perimeter of sector

Sector Perimeter = r(θ+2) r = radius θ = angle in radians

Perimeter of square

Square Perimeter = 4 × a a = length of side

Add Fractions

Step 1: Make sure the bottom numbers (the denominators) are the same Step 2: Add the top numbers (the numerators), put the answer over the denominator Step 3: Simplify the fraction (if needed) TBD

Convert to a decimal

TBD

How to put integers in order

TBD

TBD

Know what skewness is (i.e. when a distribution is skewed left or right)

TBD

Reduce Fractions

TBD

There are a few basic geometry problems regarding area and length calculation (again, formulae are given to you!)

Solving Proportions: Chef Rita is cooking for a Sunday brunch. She knows that 22 pancakes can feed 8 people. She is wondering how many people (p) she can feed with 55 pancakes. She assumes each person eats the same quantity of pancakes.

​ We're dealing with a proportional relationship, so each ratio of pancakes to people must be equivalent. 55 pancakes 22 Pancakes _______________________ = _________________________ p (People) 8 People 8x55=22xp 440=22p p=440/22 *divide both sides by 22 p=20 Rita can serve 20 people with 55 pancakes
