What do I need to know for my CCM1A

Exam?

• 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

Unit 2 – 1 Variable Statistics

• 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 Q3 + 1.5(IQR)

Q1 – 1.5(IQR)

• 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 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

Unit 1 – 1 Variable Equations & Inequalities

• 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 (subtracting a negative makes it positive)

• Multiplying Negatives & Dividing Negatives

When multiplying & dividing…. If both number are the same sign the

answer is positive If the numbers have opposite signs the

answer is negative

• Distributive Property- Distribute (multiply) 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

(and same exponent too!)• 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• 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

Unit 3 – Functions

• 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.–Examples:

• NEXT = NOW + 4• NEXT = NOW/2 • Make sure to include the START term!

• Direct Variation- • Equation: y=kx• K = constant of variation• Goes through the origin (0,0) 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

Unit 4 – Linear Functions

• Parallel Lines- never intersect, have the SAME SLOPE

• Perpendicular Lines- Slopes are opposite reciprocal

• + change to –• – change to + • Flip the fraction
