In its simplest form, amdahl's law maintains that if a given program would take one hour to run to completion with one processor

, but 80 percent of the program had to run sequentially (and therefore could not be sped up by applying additional processors to it), then a resulting parallel program would run only a maximum of ____ percent faster.

<span>20% is the maximum speed up possible for this program. For this problem, let's assign the time of 1 for the task when using a single processor. Now let's assume that we have an infinite number of processors available to handle the portion of the program that can be executed in parallel so that the execution time for that portion will be 0. That means that the total execution time with an infinite number of processors will be 1 * (0.80 + 0) = 1 * 0.80 = 0.80 So at best, the parallel program will take 80% of the time for the single threaded version. So the speed increase will be (1 - 0.80) / 1 = 0.20/1 = 0.20 = 20%</span>

An investment project has annual cash inflows of $4,300, $4,000, $5,200, and $4,400, for the next four years, respectively. The
xeze [42]

Answer:

1.64 years

2.27 years

3.13 years

Explanation:

Discounted payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative discounted cash flows

Present value of cash flow in year 1 = 4300 / 1.13 = 3805.31

Amount recovered in year 1  = -5800 + 3805.31 = -1994.69

Present value of cash flow in year 2 = 4000 / (1.13^2) = 3132.59

Amount recovered in year 2 =-1994.69 + 3132.59 = 1137.90

Payback period = 1 + 1994.69/3132.59 = 1.64 years

B

Present value of cash flow in year 1 = 4300 / 1.13 = 3805.31

Amount recovered in year 1  = -7900 + 3805.31 = -4094.69

Present value of cash flow in year 2 = 4000 / (1.13^2) = 3132.59

Amount recovered in year 2  = -4094.69 + 3132.59 = -962.10

Present value of cash flow in year 3 = 5200 / (1.13^3) = 3603.86

Amount recovered in year 3  = -962.10 + 3603.86 = 2641.76

Payback period = 2 years + -962.10 / 3603.86 = 2.27 years

C

Present value of cash flow in year 1 = 4300 / 1.13 = 3805.31

Amount recovered in year 1  = -10900 + 3805.31 = -7094.69

Present value of cash flow in year 2 = 4000 / (1.13^2) = 3132.59

Amount recovered in year 2  = -7094.69 + 3132.59 = -3962.10

Present value of cash flow in year 3 = 5200 / (1.13^3) = 3603.86

Amount recovered in year 3  = -3962.10 + 3603.86 = -358.24

Present value in year 4 =  4400 / (1.13^4) = 2698.60

Amount recovered in year 4  = -358.24 + 2698.60 = 2340.36

Payback period = 3 years + 358.24 + 2698.60 = 3.13 years

The price elasticity of supply for basmati rice (an aromatic strain of rice) is likely to be which of the following?
tiny-mole [99]

Answer: D. Higher in the long run than the short run, because farmers cannot easily change their decisions about how much basmati rice to plant once the current crop has been planted.

Explanation:

Price Elasticity of Supply refers to how Supply changes in response to a change in price. Essentially, if the price of a good increases, will Supplier supply more or less of that good as a result and by how much will they do so.

In the short run, the farmers would have already planted the crops and so would be unable start changing the quantity that they expect from the harvest. They will therefore supply the amount they harvested regardless of a price change.

In the long run however, they can change the amount of rice planted depending on the price of the rice in the market. Price Elasticity is therefore higher in the long run than in the short run.
