Across
3.Numbers or expressions that have the same value.
5.A transformation which produces a figure similar to the original by proportionally shrinking or stretching the figure.
8.An equation that states a fact or rule (e.g., A=3 r)
9.A graphical display representing data in different categories or groups. The length of a rectangle or bar is used to represent the numerical amount.
11.A plane surface of a three-dimensional figure.
14.A sequence with a constant ratio between two consecutive terms
18.The boundary of a simple 2-dimensional region, including shapes with straight and curved sides.
21.The algebraic study of geometry through the use a coordinate plane or system.
22.Special tests to determine if a particular integer is a factor of a given number, (e.g., a number is divisible by 10 if it ends in a 0).
23.A number which is placed to the right of and above another number (base). The value of the exponent determines how many times the base is used as a factor
25.The counting numbers (1, 2, 3...).
28.Two numbers are additive inverses of each other if their sum is 0.
30.A graphical display that shows data as parts of a whole circle.
32.Numeral and/or variable joined by any combination of the four basic operations (+, -, x, /) and involving any power(s) of numeral and/or variable (e.g., 3-8, 7x4, 4+X, Y/2, N-2, 3(4+8)-7, Y2-2).
33.A mathematical sentence of equality (e.g., N + 50 = 75 or 75 = N + 50 means that N + 50 must have the same value as 75).
34.A sequence with a constant difference between consecutive terms
35.A method of converting units within a measurement system.
38.A function whose general equation is a y=abx or y=abkx, where a, b, and k stand for constants.
41.The proof of a proposition by accepting the hypothesis of the proposition and arguing to the conclusion.
42.For a polygon in the plane, any line segment joining non-adjacent vertices. For a polyhedron in space, a line segment joining two vertices not in the same face.
43.The distance around a circle; the formula is pi times the diameter (C = TTd).
45.A property which establishes a relationship between multiplication and addition such that multiplication distributes across the addition [i.e., a(b+c) = ab + ac].
46.A probability calculated from the results of an experiment.
47.Geometric figures having the same size and shape; all corresponding parts of congruent figures have the same measure.
Down
1.Physical objects used to represent mathematical situations.
2.A characteristic of an object, such as color, shape, or size.
4.The amount of time between a beginning time and an ending time.
6.The size of a region measured in number of square units.
7.A display to show how often items, numbers, or a range of numbers occur.
10.A number's distance from zero on a number line
12.A relationship in which every value of x has a unique value of y
13.A graphical display which shows the median, quartiles, and extremes of a set of data but does not display any other specific data values.
15.Methods to determine the number of possible outcomes of an event. Some of the methods are tree diagram, list, rules for multiplication, combinations, and permutations.
16.A notation that describes a function. For a function ƒ, when x is a member of the domain, the symbol ƒ(x) denotes the corresponding member of the range
17.A way of writing numbers using bases and exponents [e.g., 425 = (4 x 102) + (2 x 101) + (5 x 100)].
19.The process of reasoning that starts from statements accepted as true and applied to a new situation to reach a conclusion (e.g., if 5+4 = 9, and 6+3 = 9, then 5+4 = 6+3).
20.A 2-dimensional system in which the coordinates of a point are its distances from two intersecting perpendicular lines called axes. The formal name for this system is Cartesian coordinate system.
24.A sequence rule using the number of the term to define the function [e.g., in the sequence 3, 6, 9,..., the explicit rule is f(n) = 3n where n is the number of the term and f(n) is the value of the term].
26.A property of addition or multiplication in which the regrouping of the addends or factors does not change the outcome of the operations [i.e., (a + b) + c = a + (b + c) and (ab)c = a(bc)].
27.Events in a sample space that have the same probability of occurring.
29.A pictorial representation of information or relationships between numbers.
31.A property of addition or multiplication in which the sum or product stays the same when the order of the addends or factors is changed (i.e., a + b = b + a and ab = ba).
36.The process of finding a number close to an exact amount.
37.A graphical display representing continuous data in different categories or groups.
39.The sketching of a line or curve to best describe a relationship between two variables on a scatter plot.
40.A preliminary statement or hypothesis that something is true; a statement may later be confirmed or disproved through observation or testing.
44.The numbers or terms multiplied in an expression.
