Can someone give me the answers?!! im so cunfeused and dont know how to do it
1. find the mean, varience and standard deviation for the following data set
49,32,35,43,45,40,53,55,42
2.identify the inverse of the following function
h(x)= 1 + 1/2x
There are several handy variance calculators online.
And many references on how to find the mean
you already saw how to find the inverse function.
What did you not get?
