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:

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

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

Just need question # 12. Thanks

There are two lines from the center of the circle labeled 5.

The lines at 90 degrees from the 5 are chords. Because both lines are the same distance from the center they are the same length.

The one on the top is labeled as 9, so the line on the bottom is also 9 units long.

X is half the length, so would b 9 /2 = 4.5 units long.
