Answer:
A. Recent environmental research reveals that the dust from the limestone quarrying site has severely contaminated the water at a nearby lake.
Explanation:
The limestone production results in huge social effects like, noise pollution, soil pollution, which affects lives of people. And since the manufacturers or producers of limestone do not care about the social results of such production, they shall be liable to pay huge taxes.
As for this, the cause as stated in statement A is absolutely suitable.
Also the prices are more in this area even after so much of social destruction.
Accordingly high taxes as a penalty for such social destruction shall be charged.
Answer:
9.2%
Explanation:
expected return of the investment = potential return x chance of each return happening
Expected return of the investment:
- 20% chance of occurring x 30% potential return = 0.2 x 30% = 6%
- 50% chance of occurring x 10% potential return = 0.5 x 10% = 5%
- 30% chance of occurring x -6% potential return = 0.3 x -6% = -1.8%
- total expected return = 9.2%
Hakim Goals
Explanation:

<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>
