A Simplify — a Equation at the end of step 1 : 20 (6+(——-4))-((5•1)-4) = 0 a Step 2 : 20 Simplify —— a Equation at the end of step 2 : 20 (6 + (—— - 4)) - 1 = 0 a Step 3 :Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using a as the denominator :

4 4 • a 4 = — = ————— 1 a

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

20 - (4 • a) 20 - 4a ———————————— = ——————— a a Equation at the end of step 3 : (20 - 4a) (6 + —————————) - 1 = 0 a Step 4 :Rewriting the whole as an Equivalent Fraction :

4.1 Adding a fraction to a whole

Rewrite the whole as a fraction using a as the denominator :

6 6 • a 6 = — = ————— 1 a Step 5 :Pulling out like terms :

5.1 Pull out like factors :

20 - 4a = -4 • (a - 5)

Adding fractions that have a common denominator :

5.2 Adding up the two equivalent fractions

6 • a + -4 • (a-5) 2a + 20 —————————————————— = ——————— a a Equation at the end of step 5 : (2a + 20) ————————— - 1 = 0 a Step 6 :Rewriting the whole as an Equivalent Fraction :

6.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using a as the denominator :

1 1 • a 1 = — = ————— 1 a

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
