# CLEP College Algebra Vocab

**Instructions:**

- Answer 50 questions in 15 minutes.
- If you are not ready to take this test, you can study here.
- Match each statement with the correct term.
- Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

**1. The distance across a circle through its center (is also twice the radius)**

**2. A model of an object in which the dimensions are in proportion to the actual dimensions of the object.**

**3. The sum of the values in a data set divided by the number of values in the set**

**4. A plane that is divided into four regions by a horizontal line called the x-axis and a vertical line called the y-axis - aka 'the Cartesian plane' after Ren**

**5. In an expression are separated by addition and subtraction signs**

**6. In a sum - you can add terms in any order - a + b = b + a**

**7. A number that has a whole number for a square root ex: 9 - 16 - 121**

**8. A way to figure out the total number of ways different events can occur. If there are a ways for one activity to occur - and b ways for a second activity to occur - then there are a * b ways for both to occur.**

**9. Is a number made of repeated factors**

**10. Number in front of a variable**

**11. A number that can be written as a/b where a and b are integers - but b is not equal to 0.**

**12. The smallest multiple that two or more numbers have in common**

**13. A set of three positive integers that work in the pythagorean theorem**

**14. The set of all the input (x-values) for a function**

**15. Consists of numbers - variables - and operations**

**16. Ratios that have the same value.**

**17. A diagram used to show the total number of possible outcomes in an experiment**

**18. The order of the factors does not change the product a x b = b x a**

**19. A ratio whose denominator is 100**

**20. The sum of a number and zero is always that number.**

**21. An expression constructed from a set of terms by multiplying each term by a constant and adding the results.**

**22. A letter used to represent one or more numbers**

**23. Finding all the solutions of an equation**

**24. Number of favorable outcomes divided by total number of possible outcomes**

**25. Is the middle value in a data set where the numbers are ordered least to greatest**

**26. The point in the exact middle of a circle**

**27. The bottom of a triangle**

**28. one of four sections into which the coordinate plane is divided**

**29. operations that undo each other - such as addition and subtraction**

**30. An event that is not affected by another event.**

**31. An equation that states that two ratios are equal - Ex: 1/2 = x/10**

**32. A number written as the product of its prime factors**

**33. A whole number that has exactly two factors - 1 and itself.**

**34. A number that can not be written a/b**

**35. An expression that contains a square root**

**36. The amount of 3-dimensional space occupied by an object**

**37. probability based on what happens when an experiment is actually done**

**38. To find the value of an expression**

**39. The perpendicular (90 degrees) distance from the base of a triangle to the opposite vertex**

**40. The ratio of the number of ways the event can occur to the number of ways the event cannot occur. Favorable over Unfavorable.**

**41. Consists of numbers and operations**

**42. A line segment from the center of a circle to any point on the circle (is also half the diameter)**

**43. The largest factor that two or more numbers have in common.**

**44. The total area of the 2-dimensional surfaces that make up a 3-dimensional object.**

**45. 3.1415.... is an irrational number resulting from the ratio of a circle's circumference to its diameter**

**46. A method of writing very large or very small numbers by using powers of 10**

**47. The distance a number is from 0 on the number line - value of n is written l n l**

**48. An event who's outcome does depend on the outcome of a previous event**

**49. The set of all the output (y-values) for a function**

**50. A ratio that compares two quantities measured in different units**
