Perhaps the most successful way we've been able to use light to transfer information is fiber optics. ... Through rapid changes in the light, you can send highly complex signals down the cable. These are most often used either for high speed internet connections, or for sending sound signals to home theater systems.

What do genealogists have to look forward to in the future?

Explanation:

After reading the article, the reader learns about the history of genealogy dating to as far back as ancient Rome.

Stock Y has a beta of 1.0 and an expected return of 12.4 percent. Stock Z has a beta of .6 and an expected return of 8.2 percent
Harlamova29_29 [7]

Answer: 1.9%

Explanation:

First derive the Market return as this is needed in the Capital Asset Pricing Model by using the same model:

Required return = Risk free rate + Beta * ( market return - Risk free rate)

Using stock Y:

12.4% = Risk free rate + 1 * (market return - Risk free rate)

12.4% = Rf + market return - Rf

Market return = 12.4%

Use this to calculate the Risk free rate:

Stock Z:

8.2% = Rf + 0.6 * (12.4% - Rf)

8.2% = Rf + 7.44% - 0.6Rf

Rf - 0.6Rf = 8.2% - 7.44%

0.4Rf = 0.76%

Rf = 0.76% / 0.4

= 1.9%
