2.5y + 1.1x ∠ 10
2.5y = - 1.1x +10
y = (- 1.1/2.5)x + 4
Draw this function. It's descending (m negative). All values on the left of the lines satisfy this inequality
Plug -8 in for x:
4(-8) + 5
solve:
-32 + 5
-27
<span>this is pretty hard but here is your answer
</span>
y = x^2 - 10x + 25 - 25
<span> y = (x-5)^2 - 25 </span>
<span> y+25 = (x-5)^2 </span>
<span> x-5 = +/-sqrt(y+25) </span>
<span> And you get TWO
inverses: </span>
<span> x = 5 + sqrt(y+25),
for x>=5 </span>
<span> x = 5 - sqrt(y+25),
for x<=5</span>
Answer:
22.5%
Step-by-step explanation:
let the standard deviation for market portfolio = σₙ
Also let the standard deviation for fully diversified portfolio = σₓ
<u>To calculate fully diversified portfolio</u>
fully diversified portfolio has <em>σₓ = βσₙ</em>
From the given question beta (β) = 1.25
Also standard deviation for market portfolio (σₙ) = 18% = 0.18
<em>From the equation above, σₓ = βσₙ </em>= 1.25×0.18 = 0.225
= 22.5% (converting to percentage)
<em></em>
