232 bc 15500 divided by 100 is 155 then 155 times 232 is 32860
There really isn't a right or wrong answer since this is a prediction but to solve this look at the graph and try to see the pattern
I believe it is D, stratified random sampling.
Hope this helps!!
-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1
