Polynomials, Statistics, & Geometry

• Polynomial


  A mathematical expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
• Polynomials


  • Classified according to their number of terms
• Angle


  Formed by two rays with a common endpoint called the vertex
• Degrees


  How angles are usually measured
• Line


  A straight path that extends infinitely in both directions
• Acute angle


  An angle that measures less than 90 degrees
• Straight angle


  An angle that measures exactly 180 degrees
• Straight angle


  Can form a line
• Monomial


  A mathematical expression consisting of a single term
• Two lines in a plane can have at most one point in common
• Multiply (2x + 3)(x - 5)

  2x2 – 7x – 15
• Multiply (3x - 4)(2x + 5)

  6x2 + 7x – 20
• Multiply (2x2 – 3x + 4)(3x2 + 2x – 5)


  6x4 – 5x3 + 2x2 – 15x + 20
• Multiply (3x2 – 2)(4x + 5)

  12x3 + 15x2 – 8x – 10
• (3x – 2)(4x2 + 5x + 1) "distributive property"

  12x3 + 7x2 – 7x – 2
• Edge of a table

  Represents a line
• Intersection of two sticks

  Represents a point
• Surface of a table

  Represents a plane
• Segment


  A subset of a line with two endpoints
• Population


  The entire collection of observations such as people or objects being considered
• Individual


  An observation such as a person or object included in the study
• Sample


  A small portion or part of a population
• Parameter


  Any numerical or nominal characteristic of a population
• Data


  A collection of facts or a set of information or observations under study such as numbers, words, measurements, observations, or attributes to describe things
• Variable


  May be classified as dependent or independent
• Qualitative data


  • Age of students
  • Honor section
  • Favorite tourist destinations in the country
• Quantitative data


  • Number of computers in the school
• Qualitative Data


  Data that gives descriptive information
• Quantitative Data


  A set of data that gives numerical information
• Frequency Table


  A table that shows how many times something occurs
• Grouped data


  Data that is organized and arranged into different classes and categories
• Ungrouped data


  Data that is recorded as it occurs, as it comes, or as it happens
• Class Intervals


  Shows the lower and upper limits, and class width
• Multiply (2x + 3)(3x - 4)

  6x2 + x - 12
• Multiply (x2 + 3x - 4)(2x - 1)


  2x3 + 5x2 - 11x + 4
