In cell L2, enter a formula using the IF and AND functions, as well as structured references to determine if Adam Moriarty can be a bunk leader. a. The logical test in the IF function should determine if the staff member’s Service Years is greater than 4 AND the staff member’s Leadership Training status is "Yes". Remember to use a structured reference to the Service Years and the Leadership Training columns. b. The function should return the text Yes if a staff member meets both of those criteria. c. The function should return the text No if a staff member meets none or only one of those criteria.

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
