Across
- 1. A polyhedron with a polygonal base and lateral faces that taper to an apex. A pyramid with a triangular base is called a tetrahedron.
- 5. Data is a collection of facts, numbers, or measurements gathered by observing, counting, or measuring things. In math, data usually refers to a set of numbers that you can organize, display, and analyze.
- 7. A triangle which has a right (90°) interior angle.
- 8. Addition is the operation of combining two or more numbers to find their total. The result of addition is called the sum.
- 11. Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.
- 13. All numbers on the number line. This includes (but is not limited to) positives and negatives, integers and rational numbers, square roots, cube roots , π (pi), etc. Real numbers are indicated by either Blackboard bold capital R symbol (ℝ), used to denote the set of all real numbers. or Blackboard bold letter ℝ, the mathematical symbol used to denote the set of all real numbers..
- 15. Slope is a number that describes how steep a line is and which direction it tilts. It tells you how much the line goes up or down for every unit it moves to the right.
- 16. A scatter plot is a graph that uses dots on a coordinate plane to show how two sets of numbers are related. Each dot represents one data pair, with one value on the x-axis and the other on the y-axis.
- 18. Absolute value makes a negative number positive. Positive numbers and 0 are left unchanged.
Down
- 2. An angle that has measure less than 90°.
- 3. The likelihood of the occurrence of an event. The probability of event A is written P(A). Probabilities are always numbers between 0 and 1, inclusive.
- 4. A method of computing interest in which interest is computed from the up-to-date balance. That is, interest is earned on the interest and not just on original balance.
- 6. All positive and negative whole numbers (including zero). That is, the set {... , –3, –2, –1, 0, 1, 2, 3, ...}. Integers are indicated by either Bold blackboard letter **ℤ** representing the symbol for the set of integers. or J.
- 7. A transformation in which a plane figure turns around a fixed center point. In other words, one point on the plane, the center of rotation, is fixed and everything else on the plane rotates about that point by a given angle.
- 9. A transformation in which a figure grows larger. Dilations may be with respect to a point (dilation of a geometric figure) or with respect to the axis of a graph (dilation of a graph).
- 10. A set of possible outcomes resulting from a particular experiment. For example, a possible event when a single six-sided die is rolled is {5, 6}. That is, the roll could be a 5 or a 6.
- 12. A real number less than zero. Zero itself is neither negative nor positive.
- 14. The median is the middle value in a data set when the numbers are arranged in order from least to greatest. If there are two middle values, the median is the average of those two numbers.
- 17. Two rays sharing a common endpoint. Angles are typically measured in degrees or radians.
- 19. Any and all value(s) of the variable(s) that satisfies an equation, inequality, system of equations, or system of inequalities.
