**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. Average Rate: Average A per B**

**2. 0! = ?**

**3. gcd(m,n)**

**4. 3rd Rule of Probability: Conditional Probability**

**5. In general - difficult questions require how many steps to solve?**

**6. Price purchased for by wholesaler**

**7. 1. A and B < A or B 2. A or B > Individual probabilities of A - B 3. P(A and B) = P(A) x P(B) <-- 'fewer options' 4. P(A or B) = P(A) + P(B) <-- 'more options' - Probability of multiple events rules.**

**8. Simple probability**

**9. Simple Interest Formula (remember this is the total amount of money in the bank after the interest is earned)**

**10. Dependent events: When are two events said to be dependent events?**

**11. The average of 5 numbers is 2. After one number is deleted - the new average is -3. What number was deleted?**

**12. Price sold for by retailer (after markup)**

**13. Compound interest formula**

**14. The average of consecutive numbers**

**15. How to check whether a number is a multiple of 6**

**16. Gross**

**18. 5/6 = what %**

**19. Prime Factorization to find Greatest Common Factor**

**20. Inscribed Angle - Minor Arc**

**21. 30-60-90 triangle basic lengths of sides**

**22. 2n - 2n+2 - 2n+4**

**23. If you have to guess in a problem - which ones should you guess? Especially if you have to plug numbers.**

**24. How to find all divisors of a number**

**25. Work problem rule**

**26. Always try to factor**

**27. Multiples of 3**

**28. Percent Formula**

**29. Properties of 0**

**30. How to find the slope.**

**31. Trial Problems: look at the probability of NOT OCCURRING**

**32. Net**

**33. The number of ways independent events can occur together.**

**34. How many liters of a solution that is 15% salt must be added to 5 liters of a solution that is 8% salt so that the resulting mixture is 10% salt?**

**35. Multiplication principle**

**36. 1/8 = what %**

**37. Formula for Mixed Group problems (involving Both/Neither)**

**38. Sq. rt(3)**

**39. Odd Factors**

**40. Combined Events: E or F**

**41. Think of averages as what? The average of 3 - 4 - 5 - and x is 5. What is x? 3 is 2 less than 5 4 is 1 less than 5 - 5 is the average - x = 5 + 3 = 8**

**42. Average Rate: Average speed**

**43. How do you multiply roots together.**

**44. Three triangle length patterns**

**45. Number added or deleted**

**46. When you see an equation in factored form in a question?**

**47. How to check whether a number is a multiple of 4.**
