Jake performed an experiment to find out which type of chocolate melts the fastest,
milk chocolate or dark chocolate. He tested the melting time, in seconds, of 15
different randomly selected brands of each type of chocolate in a double boiler set to
90°F. The results of the experiment are displayed in the box plots below.

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
