The given statement about the correlation between two variables is; False

<h3>Pearson's correlation coefficient </h3>

Pearson's correlation coefficient is the measure of linear correlation between two sets of data.

Pearson's r is always between the values of -1 and +1.

In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.

Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.

Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.

Select the correct statement(s) regarding Passive Optical Networks (PONs).

natta225 [31]

All the given statement(s) regarding Passive Optical Networks (PONs) are correct.

<h3>What is Passive Optical Networks?</h3>

A passive optical network (PON) is defined as a system commonly used by telecommunications network providers that brings fiber optic cabling and signals all or most of the way to the end user. Depending on where the PON terminates, the system can be described as fiber to the curb, fiber to the building or fiber to the home.

Now, there are different types of passive optical network's (PON's) such as;

APON which is ATM Passive Optical Networks.

BPON which is Broadband PON.

EPON which is Ethernet PON.

GE-PON which means Gigabit Ethernet PON.

GPON which means Gigabit Ethernet PON.

Looking at the options and comparing with the definition of passive optical network's (PON's), we can say that all the statements are correct.

The missing options are;

a. PONS does not require the use of active amplification between the CO to the subscriber

b. PONS operates over SMF optical cables

c. PONS uses passive splitters to distribute signals to subscribers

d. the PONS ONT located at the subscribers location is owned and operated by the service provider

e. all statements are correct

<h3>Who is Sir Isaac Newton?</h3>

Isaac Newton, or Sir Isaac Newton, was an English physicist and mathematician who was the pinnacle of the Scientific Revolution of the 17th century. Newton was born in Woolsthorpe, Lincolnshire, England, on December 25, 1642 (or January 4, 1643, New Style), and died in London on March 20 [or March 31, 1727].

His understanding of the nature of white light in optics helped to incorporate the color-related phenomena into the study of light and laid the groundwork for contemporary physical optics. The law of universal gravitation was developed in mechanics as a result of his three laws of motion, which are the cornerstones of contemporary physics.

jenyasd209 [6]

Answer: -3

Explanation:

since its parallel that means its on the x-axis. So, y=0.

put y=0 in the equation

3(0)-3x=12

-3x=12

x=12/-4

x=-3
