2. Jolinda needs to solve the system of equations below. 3x + 6y = 12
X + 2y = 4
She decided to use the substitution method.
Step 1:
3x + 6y = 12
x = 4 - 2
I
Step 2:
3(4 - 2y) + 6y = 12
Step 3:
12 - 6y + 6y = 12
Step 4:
y = 0
Step 5:
x= 4 - 2y = 4-20)
= 4

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.
