Answer: The portfolio with U.S. stocks only is likely to have the smallest standard deviation.
Step-by-step explanation: Standard deviation is a measure of volatility in the data, in other words, the difference between the data points. Large differences among data points lead to a higher value of standard deviation.
A portfolio with a higher proportion of international stocks is more likely to have a higher standard deviation, as international stocks may come from many different economies, thus may be affected by different economic conditions and yield different rate of returns. On the contrary, a portfolio with U.S. stocks only should get a lower value of standard deviation since all of the stocks should be uniformly affected by the economic condition of the same economy.
Answer:
Height of the building that cast a shadow of 45 meters is 27 meters
Step-by-step explanation:
This is a direct variation and let height of the object represent H and shadow represent S
Hence H∝S
H = KS, where K=constant of proportionality
K = H/S
K = 6/10 = 0.6
Hence height of a building that cast a shadow of 45 meters
H = KS
H = 0.6 × 45 = 27 meters
Answer: |-10| < |11|
So choice C. is right.
