2. 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?






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






4. How to find all divisors of a number






5. 2n - 2n+2 - 2n+4






6. 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

13. How do you multiply roots together.






14. Sq. rt(3)






15. Average Rate: Average speed






16. Since Mieko's average speed was 3/4 of Chan's - her time was 4/3 as long.

38. Simple Interest formula (remember this is only the interest earned - not the total amount of money present in the bank after interest earned)






39. 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.
