Algebraic expression (conceptual modeling)
an algebraic expression in variables is an expression constructed with the variables and algebraic numbers using addition, multiplication, and rational powers.
Conceptual modeling - An abstract model (or conceptual model) is a theoretical construct that represents something, with a set of variables and a set of logical and quantitative relationships between them
The other source of deviation is known as the bias, or systematic error, which has to do with how the observations are made, how the instruments are set up to make the measurements, and most of all, how these observations or measurements are tallied and summarized to come up with an estimate of the true parameter
A composite number is a positive integer which is not prime and not equal to 1. That is, is composite if , with and natural numbers both not equal to 1.
Conjecture (with data)
a statement which the speaker has reason to believe is correct even though the speaker cannot prove the statement
Coordinate plane (ordered pairs)
It is formed by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis. The two axes intersect at a point called the origin.
Degrees (angle)
Degree – the unit of measure used to state the size of an angle
Equation (solving)
A mathematical sentence where the left size of the equals sign has the same value as the right side.
A term used in algebra
To evaluate an expression means to find a numerical value for it, to “work it out”
A mathematical rule written using symbols, usually as an equation describing a certain relationship between quantities
Like an input/output machine; it repeats a rule to determine how each input will be changed to produce each output
Opposite, reverse operations
Measures of central tendency
Mean, median, and mode, In mathematics, an average or central tendency of a set (list) of data refers to a measure of the "middle" of the data set.
Odds (probability)
the probability that one thing is so or will happen instead of another <the odds are good it will rain today> b : the ratio of the probability of one event to that of an event that can happen instead <the odds of success to failure in throwing a six with two dice are 1 to 5>
Order of operations
The order in which operations should be done
Number out of 100
Number that has exactly two factors
Number that can only be divided evenly by itself and one
The chance that a particular outcome will occur, measured as a ratio of the total of possible outcomes
Properties of shapes and figures
Geometry is the study of the properties of shapes and figures
the size, number, or amount of one thing or group as compared to the size, number, or amount of another <the proportion of boys to girls in our class is three to one> : a statement of the equality of two ratios (as 4/2 = 10/5) -- compare
Chance pick from a number of items, like drawing a number out of a hat
Rate of change
A change in one quantity with respect to another quantity is called a rate of change.
Comparative value of two or more amounts compared to their total
One of two numbers whose product is 1; multiplicative inverse of a number (except zero)
Section of a whole group; to get data from part of a group and use it to give information about the whole group
Scale drawing
A scale drawing is a drawing that represents a real object.
The scale of the drawing is the ratio of the size of the drawing to the actual size of the object.
To reduce the numerator and denominator in a fraction to the smallest numbers possible
A simulation is an imitation of some real thing, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviors of a selected physical or abstract system.
The collection, organization, presentation, interpretation, and analysis of data; generic word for any kind of measurement or count; a statistic is a single number, computed from a sample, that summaries some characteristic of a population
Stem-and-leaf plot
A data display that shows groups of data arranged by place value
Patterns of shapes that fit together without any gaps
A change in position or size, including reflection (a flip), translation (a slide), rotation (a turn), and enlargement (a zoom)
Tree diagram
In statistical methods, a tree diagram is a schematic diagram which shows all possible outcomes of an event and the probabilities of each
Amount of space occupied by an object
