6 0

Solve for r in the first equation:

3(r+300) = 6

Use the distributive property:

3r + 900 = 6

Subtract 900 from both sides:

3r = -894

Divide both sides by 3:

r = -894 / 3

r = -298

Now you have r, replace r in the second equation and solve:

r +300 -2 =

-298 + 300 - 2 = 0

The answer is 0.

Answer:

Option a) Has an above average price-to-earning ratio

Step-by-step explanation:

We are given the following in the question:

The price-to-earning ratio for firms in a given industry is distributed according to normal distribution.

For a particular firm the ratio x has a standard normal variable has a value,

z = 1

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

$1 = \dfrac{x - \mu}{\sigma}\\\\\sigma = x - \mu\\x = \mu + \sigma$

Thus, the firm has an above average price-to-earning ratio as the ratio is one standard deviation above the mean.

Option a) Has an above average price-to-earning ratio
