Thinking with mathmatical models glossary
Acute triangle- Is a triangle with all three sides, with angles less than 90 degrees.
Additive inverse- In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation.
Base- A number that is going to be raised to a power.
Categorical variables- Is a variable that can take on one of a limited, and usually fixed, number of possible values, thus assigning each individual to a particular group or category.
Compound growth- Geometric progression ratio that provided a constant rate of return over the time period.
Correlation coefficient- A number between -1 and +1 calculated so as to represent the linear dependence, of two variables or sets of data.
Decay factor- The constant factor that each number in an exponential decay pattern is multiplied by the next value. Is the base in an exponential decay equation.
Cube root- The number that produces a given number when
Expanded form- Is a way to write numbers by adding the value of its digits.
Exponent- A quantity representing the power to which a given number or expression is to be raised.
Exponential decay- When a population or a group of something is declining, and the amount that decreases is proportional to the size of the population.
Exponential form- Is a more compact way to write something.
Exponential function- A function whose value is a constant raised to the power of the argument.
Function- A relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Growth factor- When a quantity increases exponentially over time.
Growth rate- Is the addend by which a quantity increases or decreases over time.
Hypotenuse- The longest side of a right triangle, opposite the right angle.
Inverse variation- Is a situation is in which one quantity increases while another quantity decreases.
Leg- A leg is either of the two sides that form the right angle
Math model- Is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling.
Multiplicative inverse- Is a number which when multiplied by x yields the multiplicative identity, 1.
Obtuse triangle- Is a triangle in which one of the angles is an obtuse angle.
Outlier- A data point on a graph or in a set of results that is very much bigger or smaller then the next nearest data point.
Pythagorean theorem- Is a relation in Euclidean geometry among the three sides of a right triangle.
Radius- A straight line from the center of the circumference of a circle or a sphere.
Residual- The remaining after the greater part of the quantity is gone.
Right triangle- A triangle with a right angle.
Scatter plot- The graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
Scientific notation- Used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits.
Standard deviation- A quantity calculated to indicate the extent of deviation for a group as a whole.
Slope-(of a surface or line) be inclined from a horizontal or vertical line; slant up of down.
Standard form- Is a way of writing very large or very small numbers easily.
Standard variation- Is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
Square root- Is a value that, when multiplied by itself, gives the number.
Theorem- Expressed by symbols or formula.
