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
When using an office phone or any phone for calling
someone, the two most important things to make sure is the etiquette and the
voice. This is because in the absence of visual actions or nonverbal clues when
talking through the phone, the other person on the line might likely misinterpret
what you are really trying to convey.
Answers:
<u>etiquette</u> and <u>voice</u>
Ang daan patungo sa isang malinis na paaralan ay isang malinis na silid aralan nang paisa-isa. Magsimula sa pamamagitan ng pakikipag-usap sa mga guro at mga gawaing maaari nilang magawa upang mapanatili ang kanilang silid-aralan at silid-pahingahan ng guro.
Halimbawa, ang mga bata at guro ay maaaring magtabi ng isang oras bawat linggo upang malinis at maiwaksi ang silid aralan. Ang mga guro at iba pang kawani ay maaaring maghugas ng kanilang mga tasa ng kape at baso pagkatapos magamit, at punasan ang anumang pagkalat o gulo na ginawa nila.
Ang mga pangunahing patakaran na ito ay makakatulong sa iyo at sa lahat sa paaralan na mapanatili ang isang mahusay na antas ng kalinisan sa araw-araw. Ang isang malinis na kapaligiran sa pagtatrabaho ay maaaring dagdagan ang pagiging produktibo, mapabuti ang kalagayan ng mga mag-aaral at guro, at mabawasan ang bilang ng mga pagliban.

Answer:
The correct answer is D. externalities.
Explanation:
An externality is defined as that situation or group of situations that determine that a service good is not reflected at its real market price. In this example, the computer industry is so close that they do not know for sure the benefits they have when offering their goods, and it becomes an advantage in the sense that due to its close location it is possible to establish agreements to manage prices and not enter into direct market competition.
