3. estimate:
6.8
+4.2
how come you did not estimate the problem

~11  (~ can be replaced with the word about or around)

If you were asking why one might not estimate this problem the answer is:

The values in this equation only include tenths which are not very difficult to add without rounding. While estimating can still be done, it is not necessary.

Step-by-step explanation:

When estimating, we start with rounding our numbers. In this case, we would be rounding to the nearest whole number.

6.8  ->   7     (8 is above 5 meaning we round up)

4.2  ->   4     (4 is below 5 meaning we round down)

This would leave us with the equation: 7 + 4 which equals 11.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
