Okay so you know a straight line is equal to 180 degrees, so you set them up in an algebraic equation. (5x+2)+48=180 subtract 48 first to get 5x+2=132 Subtract the 2 this time to get 130. Now you end up with 5x=130. Here you divide 130 by 5 to get X=26. If you just need to find the degree of that angle tho you can stop after the first subtraction because the math tells you (5x+2)=132 degrees.

A portfolio has a E[r] of 12% and a std deviation of 18%. T-Bills return 7%. What is the maximum level of risk aversion (A) for

solniwko [45]

<h2>The required "option D) 3.09" is correct.</h2>

Step-by-step explanation:

Given,

A portfolio has a E[r] = 12 %, and

A standard deviation ( $\sigma$ ) = 18 %

We know that,

Specify utility by U = E(r) – 0.5A $\sigma^2$

U = 0.12– 0.5(A) × $0.18^2$

= 0.12 - 0.5 × A × 0.0162

In order for the risky portfolio to be preferred to bills,

The following condition must have:

0.12 – 0.0162A > 0.07

⇒ A < $\dfrac{0.05}{0.0162}$ = 3.09

A must be less than 3.09 for the risky portfolio to be preferred to bills.

Thus, the required "option D) 3.09" is correct.

Solve for y <br> 6x - 2y = 12<br> A. y= -3x + 6<br> B. y= 3x - 6<br> C. -3x + 6<br> D. -3x - 6

ololo11 [35]

The answer is y=3x-6. (B). First you subtract 6x from both sides. Then you get -2y=12-6x. Now, you divide both sides by -2. This gets you the final answer; y=3x-6 or y=-6+3x.
