mixed number
A number that is composed of an integer and a fraction; for example, – 8 1. 4
mode
One of the measures of central tendency. The mode is the category with the greatest frequency, or the number that appears the most in a set of data. For example, in a set of data with the values 3, 5, 6, 5, 6, 5, 4, 5, the mode is 5. See also mean, measures of central tendency, median.
model
Representation of a problem, situation, or system using mathematical concepts.
non-linear relation
A relation between two variables that does not appear as a straight line when graphed on a coordinate system.
number system
A way in which number relationships are defined. For example, the base ten number system includes the digits 0 to 9, and the relationship of one place value to the next is a multiple of 10.
parameter
A special type of variable used in the definition of a subprogram, which defines the values that are inputted when the subprogram is executed.
percent
A ratio with a second term of 100. A percent is expressed using the symbol %. For example, 30% means 30 out of 100. A percent can be represented by a fraction with a denominator of 100; for example,
30%= 30. 100
point of intersection
The point at which two or more lines or curves cross. Two lines may have one point of intersection, no points of intersection, or an infinite number of points that intersect.
population
The total number of individuals or items under consideration in a surveying or sampling activity.
power
A number written in exponential form. For example, in the power 25, the base is 2 and the exponent is 5. See also base, exponent.
