g Before one game of the 1977 baseball season, Yankee manager Billy Martin put the names of his nine batters into a hat and had Reggie Jackson draw the names out of the hat in a sequential manner, and the order in which the names were drawn became the batting order for these nine players. What was the probability that the batting order that Reggie would choose would be the same batting order that Billy Martin would have preferred and chosen had he not had Reggie draw the names out of a hat

the monthly balance will be $75,000

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

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
