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
Granting access to a user based upon how high up he is in an organization violates "the principle of least privileges."
As the principle of least privileges states that a person should be given only those privileges that are needed or are necessary to perform a specific job or task and nothing more.
The principle of least privileges states that you assign users the minimum set of privileges which they require to do their jobs, according to their roles.
The principle of least privilege prevents the spread of malware on your network. An administrator or superuser with access to a lot of other network resources and infrastructure could potentially end up spreading malware to all those other systems which he gets access to.
Hence, if the organization grants access to a user based upon how high up he is then the organization violates the principle of least privileges.

Answer:
-21%
Explanation:
Initial share price = $50
Share price after 1 year = $46
net return = (200 x $46) - $10,000 - ($5,000 x 5%) = $9,200 - $10,000 - $250 = -$1,050
rate of return of margined position = -$1,050 / $5,000 = -0.21 = -21%
when you operate on the margin, your earnings can increase or decrease dramatically. In this case, an 8% price decrease resulted in a 215 lose.
