Suppose the mean rate of return on the common stocks in a large diversified investment portfolio was 12% last year. If the rates of return of the stocks within the portfolio are approximately normally distributed and a rate of return of 15% represents the 80th percentile, what is the approximately standard deviation of the rates of return in the portfolio?

answer

106 emergencies

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
