Standard deviation rate of return is a measure of risk in the stock market. an investment manager claims that the standard deviation rate of return for his portfolio is less than the general market, which is known to be 18%. treating the past 10 years as a random sample, you find the standard deviation rate of return of the manager’s portfolio is 16%. does this represent sufficient evidence to conclude that the investment manager’s portfolio has less risk than the general market? use a = 0.05.

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

they r 125, and 216

so the sequence goes 1,8,27,64,125,216
