Study Notes
Key Algebra Concepts
- Binomial: A polynomial with exactly two terms, important for understanding polynomial operations.
- Extrapolate: Estimating values outside known data points, useful in predictive statistics.
- Zero: Important concept, a denominator cannot be zero in fractions to avoid undefined results.
- Quadratic Equation: Form represented by x^2 + 2x + 1 = 0; characterized by its degree of 2.
- Equation: A mathematical sentence that equates two expressions, fundamental in algebraic manipulation.
- Distributive Property: Illustrated by 4(x + 2) = 4x + 8, crucial for simplifying algebraic expressions.
Additional Mathematical Terms
- Linear: Refers to a first-degree equation, representing a straight line in graphing.
- Variable: Symbol representing a quantity that can change, essential for algebraic expressions.
- Slope: The ratio of vertical change to horizontal change, key in linear equations and graphs.
- Trinomial: A polynomial with precisely three terms, similar to binomials but with an additional term.
- Deviation: Spread of data around the mean, standard deviation is a common measure.
- Line of Best Fit: Used in linear regression; the best fit line approximates the relationship between variables.
Data and Statistical Measures
- Sum: Result of number addition, reflects the total value.
- Root: The solution of the equation where f(x) = 0, indicates where the graph intersects the x-axis.
- Perimeter: Total distance around a shape; essential in geometry.
- Intercept: The point where a line crosses the x-axis, indicates the value of x when y = 0.
- Product: Result of multiplying numbers, reflects combined value.
- Median: The middle value in a sorted dataset, useful for determining central tendency.
Other Important Terms
- Box Plot: Visualization technique using box and whiskers, illustrates data distribution.
- Maximum: The peak value on a graph, indicates the highest point reached.
- Hypotenuse: The longest side opposite the right angle in a right triangle.
- Rational Number: Expressible as a fraction a/b (where b ≠ 0), essential in number theory.
- Base: The number raised to a power in exponential expressions.
- Parallel Lines: Lines that share the same slope, never intersect.
- Correlation: Statistical measure indicating the degree to which two variables move in relation to each other.
Sets and Data Representations
- Roster: A complete list of elements in a set.
- Integers: Set including negative numbers, zero, and positive numbers {...,-3,-2,-1,0,1,2,3,...}.
- Horizontal Line: A line with a slope of zero, indicating no vertical change.
- Exponent: Represents how many times a number or expression is multiplied by itself (e.g., the "2" in 3x²).
- Scientific Notation: Method of expressing very large or small numbers concisely.
- Vertex: The turning point of a parabola, key in graphing quadratic functions.
- Interpolate: Estimating values within known data ranges, contrasting with extrapolation.
Functions and Statistical Analysis
- Function: A relation where each x value corresponds to exactly one y value, essential concept in algebra.
- Mode: The most frequently occurring value in a data set, useful for understanding data distribution.
- Mean: The average value calculated by summing all data points and dividing by the number of points.
- Residual: The difference between actual data points and values predicted by a statistical model, crucial for accuracy assessment.
- Cubic: Relating to volume, often denoted in units such as cubic centimeters or cubic meters.
