We have
1*1 + 8*1/100 + 9*1000

this can be written as,
1 + 0.08 + 0.009

we get 1.089

hope this help

Yes, well there can be many reasons but actually its not inconsistent as there are no zero rows meaning there is no row that just has 0's

2>8−4/3h Solve the inequality
Goryan [66]
It'd be best if you were to enclose that fraction 4/3 inside parentheses:

<span>2>8−(4/3)h

Mult. all 3 terms by 3:            6>24 -4h
Add 4h to both sides:          +4h      +4h
                                           ------------------
                                            7+4h > 24
Subtract 7 from both sides:    -7       -7
                                            ------------------
                                              4h > 17

Then h>17/4 (answer)   Note:  We want h to be positive.  That's why I moved (-4/3)h to the other side of the = sign.</span>

Salma invests the following sums of money in common stocks having expected returns as follows: a. what is the expected return (p
Contact [7]

Calculate the total amount invested by summing up all the values of the investment.

Total = 50,000

Calculate the weight of each investment. For WOOPS, weight = 5000 / 50000 = 10% and so on.

Now, Expected Return = sum of weight x Returns = 10% x 0.14 + 20% x 0.16 + ... + 18%x 0.18 = 16.01%

b) Similarly,

Beta of the portfolio = sum of weight x beta = 10% x 0.6 + 20% x 0.8 + ... + 18% x 0.18 = 0.7605

c) Portfolio has less systematic risk as the beta for the average market is 1, which is above the portfolio

d) Using CAPM, Return = Rf + beta x (Rm - Rf) = 4% + 0.7605 x (14% - 4%) = 11.605%

To calculate the expected return of a portfolio, the investor needs to know the expected return of each security in the portfolio and the total weight of each security in the portfolio. This means that investors need to sum the weighted averages of the expected returns (RoRs) of each security.

Investors are based on estimates of the expected rate of return on securities, assuming that what has proven to be true in the past will be true in the future. Investors do not use the structural view of the market to calculate the expected return. Instead, it determines the weight of each security in the portfolio by dividing the value of each security by the total value of the security.
