A local bank has determined that on average a teller can process 5 transactions per 15 minutes. What is the new mean of processed transactions if the time is changed to a 25 minute interval?

The new mean of processed transactions is 8

Step-by-step explanation:

The teller averages 5 transactions every 15 minutes.

Taking this to a single transaction basis gives; The teller averages one transaction every 3 minutes.

So, when the time changes to 25 minutes, there is the need to find the number of 3-minutes obtainable from a 25-minute interval

New mean of processed transaction = = 8.333

The new mean of transaction every 25 minutes is about 8 transactions

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
