Answer:
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Explanation:
To calculate the standard deviation of the investment, we must first calculate the expected or mean return of the investment. The expected or mean return can be calculated as follows,
r = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability of state occurrence
- rA, rB, ... represents return A, return B and so on under each state
r = 0.2 * 0.16 + 0.4 * 0.12 + 0.2 * 0.05 + 0.2 * -0.05
r = 0.08 or 8%
The formula to calculate the standard deviation of a stock/investment is as follows,
SD = √pA * (rA - r)² + pB * (rB - r)² + ... + pN * (rN - r)²
SD = √0.2 * (0.16 - 0.08)² + 0.4 * (0.12 - 0.08)² + 0.2 * (0.05 - 0.08)² + 0.2 * (-0.05 - 0.08)²
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Answer:
The plant would have to work 8.33 hours
Explanation:
Initial productivity:
100 parts were produced in 1 hour
Percentage increase in productivity = 20%
New productivity:
100 + (100 × 0.2) = 100 + 20 = 120
120 parts would be produced in 1 hour
Number of hours the plant would have to work to produce 1000 parts = 1000/120 = 8.33 hours

Answer:
True (Dead-weight loss )
Explanation:
When the market is not allowed to adjust towards the equilibrium the economics efficiency is lost. When the supply is excessive compared to demand some part of supply remains intact, which means that small of amount of supply does not contribute to economics and allocation efficiency and considered as a dead-weight loss. The supply is forgone because the market is not allowed to stabilise.
Answer:
The invaders were able to govern the more advanced civilizations because they adopted most of the conquered civilizations' customs, rules of governance, and even languages and religion.
For example, in the case of the Germanic tribes that conquered the Western Roman Empire, the rulers adopted, one by one, the religion of the Roman Empire: Christianity, more specifically, the Roman Catholic variant.
They also began to use the language of the Empire: Latin, for ecclessiastical and political matters, and while political institutions did change a lot, some of the political institutions of the Empire did survive in the sucessor states that the Germanic rulers carved out of the Roman territory.
