You have to use a calculator for both of the exact values using sin^-1 or Cos^-1 you can then times those together, with the final part the answer is sin 240 as sin(A-B) = sinAcosB-CosASinB
Answer:
The range is the difference between the largest and the smallest observation in the data. The prime advantage of this measure of dispersion is that it is easy to calculate. On the other hand, it has lot of disadvantages. It is very sensitive to outliers and does not use all the observations in a data set.
4/5*6=4,this is your answer.
3/4*5=3 3/4,this is also your answer.
Hope this helps
