Answer:
Given that Program instructions consists of:
- 60% floating point multiply
- 20% floating point divide
- 20% other instructions
Amdahl's law states that:
Execution time affected by improvement = (Execution time after improvement/ Amount of improvement) + (Execution time unaffected)
Assuming initially that floating point multiply, divide and other instructions have same clocks per instruction (CPI).
Part (a)
New execution time after improvement with multiply = (60) / 8 + (20 + 20) = 47.5
New execution time after improvement with Divide = (20) / 3 + (60 + 20) = 86.67
New system should be 4x faster which means new execution time should be below = 100/ 4 = 25.
Therefore, Management's goal can NOT be achieved by making the improvement with multiply or divide alone.
Part (b)
New execution time after improvement with multiply and divide = (60 / 8) + (20 / 3) + 20 = 34.17
Speed up = execution time of original machine / Execution time of new machine = (100 / 34.17) = 2.93
Therefore, new machine is 2.93 times faster than original machine.
There are quite a few reasons that this difference could be
observed. The lower black median age could be connected to the greater number
of births in the black minority group than in the whites. Another reason could
be the aging of the non-Hispanic white group to a post child-bearing age and consequently
the general aging of this subgroup of the population. In general, differences
in group medians are due to the distribution of ages and the observed range of
the ages in the two dissimilar population groups.
Answer: Decrease your take-home pay and decrease your federal income taxes in the current year. A 401k allows you to deduct earnings from your current income, and put that money in an account that cannot be opened until around retirement. The money put into a 401k, and the returns earned on that money through interest or investments, is not taxed as income until you take it out after retirement. This means that, when you put some of your earnings in a 401k, your take-home pay is lower for that year (you can't spend that money) and your income tax is reduced.
Answer:
A
Explanation:
The privately-owned school system in Smalltown generates positive externality to members of SmalltownA good has positive externality if the benefits to third parties not involved in production is greater than the cost. an example of an activity that generates positive externality is research and development. Due to the high cost of R & D, they are usually under-produced. Government can encourage the production of activities that generate positive externality by granting subsidies.
The free rider problem is a form of market failure. It occurs when people benefit from a good or service of communal nature and do not pay to enjoy these services.
The free rider has caused a decline in revenues and did not cause the private market to undersupply education to the community
Octavia should tell the customer that she doesn’t know the answer right now, but she will try to figure it out as soon as possible, and it may take a few days.
Another great option is for Octavia to ask a coworker right away who may know the answer to the question.
