Project 1

3. A mathematical sentence with an equals sign (like 3x+5=11).
5. grid A grid used to illustrate values of algebraic expressions.
7. plot A diagram showing data values as dots above a number line.
8. A single fixed number (unlike a variable, whose value can vary).
10. An expression that is used to compute a value.
12. number A number that cannot be written as a fraction
14. More than any finite (real) number.
15. root The cube root of a, written 3√a, is the number whose cube is a. That is, (3√a)3=a.
16. The most common value in a collection, or “modes” if more than one are tied.
19. number A value less than zero (like −3).
20. Rewriting an expression as a product.

1. m and n are integers.
2. A number that is raised to a power.
4. An expression that is multiplied by another expression, or that can be multiplied by another expression to produce a specified result.
6. model An estimate for a variable using a linear expression in another variable.
7. The distance between two quantities, or the answer to a subtraction problem.
9. value The distance a number is from 0
11. plot A box with “whiskers” showing the median, quartiles, and extremes (least and greatest values) of a collection of data values.
13. Going from side to side, like the horizon.
17. A collection of related measurements.
18. A number that can be “put into” a relation to produce one or more “outputs.” If a relation is given by a two column table of rows (x,y), you “look up” the input x value in the first column, and the output(s) are given by the y values in those matching row(s).
