If the risk-free rate is 7 percent, the expected return on the market is 10 percent, and the expected return on Security J is 13

Lelu [443]

Answer:

0.02 or 2% = Beta

Step-by-step explanation:

Given that,

Risk-free rate = 7 percent

Expected return on the market = 10 percent

Expected return on Security J = 13 percent

Therefore, the beta of Security J is calculated as follows;

Expected return on Security J = Risk-free rate + Beta (Expected return on the market - Risk-free rate)

13 percent = 7 percent + Beta (10 percent - 7 percent)

0.13 - 0.07 = 0.03 Beta

0.06 = 0.03 Beta

0.06 ÷ 0.03 = Beta

0.02 or 2% = Beta

what is the X co-ordinate of vertex of parabola where equation is Y is equal to X square + bx + c =\ o

torisob [31]

Answer:

x = - $\frac{b}{2}$

Step-by-step explanation:

Given a quadratic equation in standard form , that is

y = ax² + bx + c = 0 ; a ≠ 0

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

x² + bx + c = 0 ← is in standard form

with a = 1, b = b, thus

$x_{vertex}$ = - $\frac{b}{2}$

y varies inversely with x. If y = 2.4 and k (the constant of variation) = 8.88, what is x? Round to the nearest tenth, if necess

Archy [21]

Answer:

3.7

Step-by-step explanation:

Inversely means we are taking the constant and dividing it.

So y varies inversely with x means "y=k/x".

k is a constant. We can find the constant if they give us a point on this curve.

The constant is a number that doesn't change no matter your input and output.

$y=\frac{k}{x}$

So they actually give us k=8.88 and y=2.4 so let's input this:

$2.4=\frac{8.88}{x}$

We need to solve this equation for x. You can do your favorite thing in cross-multiply. But how, Freckles? Well just slap a 1 underneath that 2.4. You can do that because 2.4/1 is still 2.4.

$\frac{2.4}{1}=\frac{8.88}{x}$

Cross-multiply:

$2.4x=8.88(1)$

$2.4x=8.88$

Divide both sides by 2.4:

$x=\frac{8.88}{2.4}$

$x=3.7$ when $y=2.4$ .

Add 6 to both sides
2x-6+6=4+6
Simplify 4+6 to 10
2x=10
Divide both sides by 2
2x/2=10/2
Simplify 10/2
x=5
