Essential Formulas for Algebra 2 Final Exam. Laws of Exponents. ≠ b + a a +. = b × a a × b. ≠ b − a a −. = b ÷ a a ÷ b. Properties of Radicals. Distribution of Radicals of the Same Index. (where a ≥ 0 and b ≥ 0 if n is even) n ab = ( n. )( n. ) n a = n a n b. Power Rule of Radicals = Multiplying Exponents. m n ( a m × n ) = a.
Part 1 presents mathematical formulas together with other material, such as definitions, theorems, graphs, diagrams, etc., essential for proper understanding and application of the formulas.
Statistics Formulas: Given: represents an element of the data set, th represents the element of the data set, i. represents the number of elements in the data set, n. represents the mean of the data set, μ.
Measures of Central Tendency: Mean: Average. Median: Middle (put numbers in order and find middle) Mode: “Most” (number that appears the most) Q1: Quartile 1=Median of first half of data Q2: Quartile 2=Median of all data. Q3: Quartile 3=Median of second half of data.
Algebra Formulas. 1. Set identities. Definitions: I: Universal set A’: Complement. Empty set: ∅. Union of sets. A ∪ B = { x | x ∈ A or x ∈ B } Intersection of sets. A ∩ B = { x | x ∈ A and x ∈ B } Complement. A ′ = { x ∈ I | x ∈ A } Difference of sets. B \ A = { x | x ∈ B and x ∉ A } Cartesian product. × B = { ( x , y ) | x ∈ A and y ∈. }
Mean Absolute Deviation. The sum of the distance between each data value and the mean, divided by the number of data values. Standard Deviation.
