estimate,
round off answer |
| Absolute
value |
The
absolute value of a number is its distance from zero on a number line. If
x is the coordinate of a point on a number line, the distance from that
point to the origin is called the absolute value of x, written lxl. This
distance is always either positive or zero. |
| Adjacent
vertices |
Two
vertices that are joined by an edge. |
| Algebra |
The
generalization of the ideas of arithmetic. A branch of mathematics where
unknown numbers can be represented by letters and their values found to
solve numbers. |
| Algorithm |
A
systematic scheme for carrying out computations, usually consisting of a
set of rules or steps, the long division algorithm is an example. |
| AREA |
region
enclosed by a plane figure |
| Area |
The
number of square units in a region. |
| Arithmetic
sequence |
A
sequence in which each term is equal to the preceding term plus a
constant. This constant is called the common difference. |
| Array |
A rectangular arrangement of objects in rows and columns. |
| Axis of
symmetry |
A
line over which an image mirrors itself. |
| bar graph |
uses
vertical or horizontal bars to show data - a good way to represent data
that compare |
| BASE OF A PYRAMID |
bottom
side of a pyramid |
| Best-fit
line |
The
linear equation that meets the agreed-upon criteria for a set of data. |
| bimodal distribution |
a
bimodal distribution is one in which there are two common responses from
survey respondents |
| Binomial |
A
polynomial with two terms, for example 2x + 3. |
| Box and
whisker plot |
A
graphic way of showing a summary of data using the median, quartiles, and
extremes of the data. A box and whisker plot makes it easy to see where
the data are spread out and where they are concentrated. The longer the
box the more the data are spread out. |
| CIRCUMFERENCE |
the
distance around a circle |
| Cluster |
A group of related math problems.
(Example: 2x5, 40x5, 42x5, 20x5, 42x10) |
| Coefficient |
In
algebra, the numerical factor of a term (e.g., in 4x2, 4 is the
coefficient). |
| Coefficient
of correlation |
A
measure of the strength of the linear dependency of y on x. It can be used
to decide if a line is a good model of the data or of the accuracy of any
prediction based on that linear model. |
| Combination |
A
selection of objects from a set in which order is not important. |
| common denominators |
denominators
that are the same |
| common factor |
a
number that is a factor of two or more different numbers |
| Complex
number |
The
sum of a real and an imaginary number written in the form a + bi. |
| Composite
Number |
A whole number greater than one with more than two different
factors. For example, 6 is a
composite number. Its factors are 1, 2, 3, and 6. |
| Composition
of functions |
The
process of using the output of one function as the input for another
function. |
| Compound
interest |
Interest
paid on earned interest. |
| Congruent |
Two
geometric figures that are the same shape and size. |
| CONGRUENT (CONGRUENCE) |
same
size and same shape |
| Coordinate Grid |
two
crossed number lines that are called x axis(horizontal) and y |
| coordinates |
ordered
number pair used in graphing (i.e. 1960, 56) |
| COORDINATES |
location
of a point in the (x,y) coordinate system |
| Cosine |
The
cosine of an acute angle in a right triangle is the ratio of the length of
the adjacent leg to the length of the hypotenuse. |
| Counting
principle |
If
there are n1 ways to make a first choice, n2 ways to make a second choice,
n3, ways to make a third choice, and so on, then the product n1 • n2 •
n3• ... represents the total number of different ways (outcomes) in
which the entire sequence of choices can be made. |
| CUBE |
a
rectangular prism whose faces are all square |
