Answer:
portfolio's standard deviation = 0.3256
Explanation:
Stock Expected Return Standard Deviation Wi
A 10% 30% 0.2
B 20% 40% 0.8
covariance = [(10% - 10%) x (20% - 20%)] / (2 - 1) = 0
portfolio's standard deviation = (stock A's Wi² x variance) + (stock B's Wi² x variance) + (2 x covariance x weight A x weight B)
portfolio's standard deviation = √{(0.2² x 0.09) + (0.8² x 0.16) + 0} = √(0.0036 + 0.1024) = √0.106 = 0.3256

<h3>What is
income?</h3>
Income is the consumption and saving opportunity gained by an entity over a given time period, which is usually expressed in monetary terms. Income is difficult to define conceptually, and definitions vary across fields.
Income is defined as the amount of money received by a person, group, or company over a specific time period. A salary of $70,000 per year is an example of income.
Income is money received by an individual or business in exchange for labor, the production of a good or service, or the investment of capital. Individuals typically earn money through wages or salaries, whereas businesses make money by selling goods or services for more than their cost of production.

Answer:
The APY is 14.9%
Explanation:
To find the annual percentage yield we need to compute the effective annual rate of interest.
The Effective annual rate of return(EAR) is the equivalent rate to be paid where compounding is done frequently at period or interval less than a year.
Compounding implies the regular interval when interest is always computed; in this scenario, it is monthly.
The EAR can be worked out as follows
EAR = ( (1+r)^m - 1 ) × 100
r- interest rate per period
m- number of periods in a year
EAR - Effective annual rate
r = 3.5%/3 = 1.167
% per month
m= number of months in a year = 12
EAR =( 1.01167^12-1)× 100 = 14.9%
The APY is 14.9%
This implies the quoted interest rate of 3.5% per quarter is the same as paying 14.9% per year
