Answer: 102
Step-by-step explanation:
The given data set :
We know that the range of a data set is the difference between maximum value and the minimum value of the data set .
In the given data set, Maximum value = 199
Minimum value =97.
Then , the range of this set =
Hence ,the range of the given data set = 102.
Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,
Hence, this is the required solution.
