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.

Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the rate of change or slope
A hot air balloon is descending at a rate of 287 feet per minute.
Thus, the rate of change m = -287
The negative sign indicates that a hot air balloon is descending.
Let y be elevation.
Let x be the time (in minutes)
As there is no mentioning of the initial height.
Thus, the y-intercept b = 0
now substituting m = -287 and b = 0
y = mx + b
y = -287x + 0
y = -287x
In order to determine the total change in elevation of the balloon in 4 minutes, we need to substitute x = 4 in the equation y = -287x.
Thus, the total change in elevation of the balloon in 4 minutes will be:
y = -287x
y = -287(4)
y = -1148 feet
The negative sign indicates that that the elevation is decreasing.
