To determine the standard deviation of a portfolio, you would need to calculate the weighted average of the individual asset standard deviations and their correlations. This involves multiplying the squared weight of each asset by its standard deviation, adding these values together, and then taking the square root of the result. This calculation helps measure the overall risk and volatility of the portfolio.
the incerase is adding and the decrease is subtracting :)
s= bracket n over sigma i (xi-x-)^2 all over n-1 closed bracket ^ 1/2
Decrease
no
The acidity can be lowered by adding a base.
In a normal distribution, approximately 95% of the population falls within 2 standard deviations of the mean. This is known as the 95% rule or the empirical rule. The empirical rule states that within one standard deviation of the mean, about 68% of the population falls, and within two standard deviations, about 95% of the population falls.
decrease because the amount of debt changes
Adding an acid the pH decrease.

Adding more water will decrease the salt concentration.
