Sven is trying to find the maximum amount of time he can spend practicing the five scales of piano music he is supposed to be working on. he has 50 minutes to practice piano and would like to spend at least 15 minutes playing songs instead of practicing scales. so, sven sets up the following inequality, where t is the number of minutes he spends on each scale, and solves it.
50 − 5t ≤ 15
−5t ≤ −35
t ≥ 7
sven has concluded that he should spend 7 minutes or more on each scale. is this correct? if not, what mistake did he make? then solve for the correct answer.

Solve the system of equations. y= 2x y= x^2 - 15

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.
