Stock A ‘s returns have a standard deviation of 0.5, and stock B’s returns have standard deviation of 0.6.The correlation coefficient between A and B equals 0.5. What is the variance of a portfolio composed of 70 percent Stock A and 30 percent Stock B?

The variance of the profile is 0.2179.

Step-by-step explanation:

We are given the following in the question:

Variance of portfolio is given by:

Putting values, we get,

Thus, the variance of the profile is 0.2179.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
