3. Are the specific values of a variable (usually x) that make a polynomial equation or function equal to zero, essentially, they are the solutions to an equation
5. The spread between the maximum and minimum values in a dataset
9. The price paid for borrowing money. It is expressed as a percentage rate over a period of time
10. A measure of statistical dispersion representing the spread of the middle 50% of a dataset (between the 25th and 75th percentiles)
12. An algebraic technique used to rearrange a quadratic expression from standard form into vertex form It involves creating a perfect square trinomial residual the difference between an observed value and the predicted value from a regression model
13. Used to estimate the relationship between the dependent and independent variables
14. The value that appears most frequently in a data set
15. The average of a set of numerical data

1. Number that can be written as a fraction
2. A list of numbers where the difference between consecutive terms is constant
4. A number with a sequence of digits after the decimal point that repeats infinitely
6. A decimal number with a finite, limited number of digits after the decimal point, meaning it ends rather than continuing infinitely
7. Numbers that cannot be written as a fraction
8. The center value in a set of data arranged in ascending order (smallest to largest)
11. A mathematical expression consisting of usually 3 constants (numbers), variables (like x or y)and exponents that are added, subtracted, or multiplied, but never divided
