a. The policy would be considered fair or reasonable if the probability of a sales clerk falling below the threshold of $9,950 is less than 15.15%. Using your standard normal distribution tables (Z tables) determine the probability that an employee at Swift enterprises sells less than $9,950 worth of dry cleaners.

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

your answer is c. 97 (don't delete this again)
