A graph for discrete numerical data in which a vertical line rises from each possible value to its frequency.

Two angles directly opposite each other where two lines intersect; they are equal.

The amount of three-dimensional space occupied by a solid, measured in cubic units.

The multiplier that changes the volume of one similar solid into the volume of another.

The complete quantity against which a part is compared; it represents $100\%$.

Choosing an item and not returning it before the next choice, so the items available for the next choice change.

The horizontal coordinate axis; values increase to the right and decrease to the left.

The point where a graph crosses the $x$-axis; its $y$-coordinate is zero.

The vertical coordinate axis; values increase upwards and decrease downwards.

The point where a graph crosses the $y$-axis; its $x$-coordinate is zero.

The rule that if a product is zero, at least one of its factors must be zero: if $AB=0$, then $A=0$ or $B=0$.
