Suppose that a machine with a 5-stage pipeline uses branch prediction. 15% of the instructions for a given test program are bran
ches, of which 84% are correctly predicted. The other 16% of the branches su er a 4-cycle mis-prediction penalty. (In other words, when the branch predictor predicts incorrectly, there are four instructions in the pipeline that must be discarded.) Assuming there are no other stalls, develop a formula for the number of cycles it will take to complete n lines of this program

Answer:
RANK.AVG
Explanation:
Required
Arrange data in descending order based on average
The feature to do this is to use the RANK.AVG() function.
By default, the function will return the ranks of the selected data in descending order (i.e. from highest to lowest); though, the sort order can be changed to ascending order.
The syntax is:
=RANK.AVG (number, ref, [order])
Where
number The number to use as rank
ref The cell range
order 0 represents descending order while 1 represents ascending order
