Stocks A and B have the following returns: A B

1 A 0.09 B. 0.06

2 A 0.06 B. 0.04

3 A 0.14 B. 0.06

4 A -0.03 B. 0.03

5 A 0.07 -0.05

a. What are the expected returns of the two stocks?

b. What are the standard deviations of the returns of the two stocks?

c. If their correlation is 0.48 , what is the expected return and standard deviation of a portfolio of 52% stock A and 48% stock B?

answer: 1, 3 and 5 are correct

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
