Review of CCM1 Part 1 Take about 5 minutes INDIVIDUALLY to fill out the tables on the worksheet. Write down anything you remember about the specific topic http://www.online-stopwatch.com/

Take about 10 minutes to talk about your answers with your partner

What do I remember from CCM1 A?

Describing Data: Address Shape, Outliers, Center, Spread Mean- average Median- middle number Standard Deviation- How much variation exists from the average Range-The difference between the highest and lowest number

Box Plot- Use the 5 number summary Dot Plot- Histogram-

5 Number Summary- Minimum, Q1, Median, Q3, and Maximum IQR- The difference between Q3 and Q1 (Q3-Q1) Outliers- A number that is numerically distant from the rest of the data

Categorical – data that can be separated by category EX) sorting students by the model of car they have   Quantitative – data that can be separated by numerical values EX) sorting students by the number of siblings they have

Algebraic Equations- has an equal sign Order of Operations- (PEMDAS) Algebraic Expressions- Does not have an equal sign, You evaluate (simplify or solve) Algebraic Expressions Algebraic Equations- has an equal sign Order of Operations- (PEMDAS) Parenthesis Exponents Multiplication/Division Addition/Subtraction Evaluate- means to simplify or solve

Variable- a symbol that stands for a number Solving Equations- Follow reverse order of operations to get the variable by its self on one side of the equation Whole Numbers- Includes zero and all the positives (no fractions or decimals) Integer- Includes all negatives, zero, and all positives (No fractions or decimals) Variable- a symbol that stands for a number Ex) x – 2 = 10 X is the variable

Subtracting Negatives- Keep, change, change Multiplying Negatives- Neg·Neg = Pos Neg·Pos = Neg Pos·Neg = Neg Pos·Pos = Pos Dividing Negatives Neg ÷ Neg = Pos Neg ÷ Pos = Neg Pos ÷ Neg = Neg Pos ÷ Pos = Pos

Distributive Property- Distribute to EVERYTHING inside the parenthesis Constant- just a number, does not have a variable Coefficient- The NUMBER in front of (multiplied by) a variable Like Terms-Terms with the same exact variables Substitution- Putting a number in place of a variable to simplify an expression Equivalent expression- two expressions that have the same most simplified form

Less Than < Less than or equal to ≤ Greater Than > Greater Than or Equal To ≥ Open Circle- Use for < or > Closed Circle- Use for ≤or ≥ Solving Inequalities- Solve like you solve equations; Follow reverse order of operations ** Flip the inequality symbol when multiplying or dividing by a NEGATIVE

Domain Range Independent Variable X’s Goes on x-axis Goes in L1 when finding line of best fit Range Dependent Variable Y’s Goes on y-axis Goes in L2 when finding line of best fit

Function X values do not repeat (vertical line test) Function rule { ex. f(x) = 2x + 3} Equation

Function Notation f(x) = Example: f(x)= 2x + 4 Now-Next Rule: A recursive rule found by relating a number to what comes before it. Written as Ex) NEXT = NOW + 4 Start = Ex) NEXT = NOW/2 Start =

Direct Variation- Equation: y=kx K = constant of variation (slope) Goes through the origin on a graph Finding slope through 2 ordered pairs: (x1, y1) (x2, y2)

Slope- Intercept Form: y = mx + b M = slope; B = y-intercept Point Slope: y – y1 = m( x – x1) M = slope; X1, y1 are from the ordered pair Standard Form: Ax + By = C No Fractions, C is a constant

Parallel Lines- never intersect, have the SAME SLOPE and DIFFERENT y-intercepts Perpendicular Lines- Slopes are opposite reciprocal + change to – – change to + Flip the fraction
