Answer: A.
The inverse sine function is written as sin−1(x) or arcsin(x). Inverse functions swap x- and y-values, so the range of inverse sine is − π/2 to π/2 and the domain is −1 to 1. When evaluating problems, use identities or start from the inside function.

Answer:
Your friends data
Step-by-step explanation:
The rule of statistics is: the more exact the data, the better.
Here it seems that you got less precise data, as you can see. This also causes the possibility of mistakes.
This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.
This means that your friend had better data than you.
Hope this helped!
