Q$9.$ What is the output of mean $(v1+v2)?$ How does that compare with the output of ${\displaystyle \underset{?}{\overset{?}{}}}\frac{v1+v2}{?}$ length $(v1+v2)?$

Q$10$: You can sort or round the elements of a vector using functions sort $()$ and round$().$ Try them out on the elements of mean $(v1+v2)$ by first assigning this quantity to a variable called my$\_$vector and then applying these functions to my$\_$vector.
