Sandy programmed a website's checkout process with an equation to calculate the amount
customers will be charged when they download songs. The website offers a discount. If
one song is bought at the full price of $1.29, then each additional song is $.99.
This situation is represented by the equation C(s) = 1.29+.99(s - 1), where C(s) represents
the total cost, and s represents the number of songs downloaded.
What is the reasonable domain and range?

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.
