Answer:

The answer is "False".

Explanation:

Time-domain applies, in the context of the time, to the study of numerical mechanisms, physical signals or time series of financial or environmental information.

It is a research system, that provides the solutions of linear equation, and also provide program.
It is a description of a control unit through a universal algebraic equation of time factors, that's why this option is false.

Assume X and Y are indepndent. Assume that X has mean 10 and standard deviation 8. Assume Y has mean 12 and standard deviation 6

Vitek1552 [10]

Answer:

$\sigma_z = 10$

Explanation:

Given

$\bar x = 10$

$\sigma_x = 8$

$\bar y = 12$

$\sigma_y = 6$

$z = x + y$

Required

$\sigma_z$

This is calculated as:

$\sigma_z = \sqrt{Var(x) + Var(y)}$

Calculate $Var(x)$

We have:

$Var(x) = \sigma_x^2$

$Var(x) = 8^2$

$Var(x) = 64$

Calculate $Var(y)$

We have:

$Var(y) = \sigma_y^2$

$Var(y) = 6^2$

$Var(y) = 36$

So, we have:

$\sigma_z = \sqrt{Var(x) + Var(y)}$

$\sigma_z = \sqrt{64 + 36}$

$\sigma_z = \sqrt{100}$

$\sigma_z = 10$

Which is a disadvantage of pie charts?

anzhelika [568]

While the reader of a pie chart can clearly see which categories dominate, it can be difficult to see categories that occupy only a small percentage of the chart. This problem becomes worse if there are many small categories in the chart. Labeling the categories can also be difficult.

Sedbober [7]

Classless Inter-Domain Routing gets its name from the notion that it ignores the traditional A, B, and C class designations for IP addresses and can therefore set the network-host ID boundary wherever it wants to, in a way that simplifies routing across the resulting IP address spaces.

Explanation:

A router is a networking device that helps in connecting multiple networks. Classless Inter-Domain Routing (CIDR) is used for creating IP addresses and IP routing. CIDR was introduced in the year 1993 by “The Internet Engineering Task Force”. The classful network design was replaced by CIDR in the Internet.

The IP addresses are responsible for sending the particular information packets to specific computers. Classless inter-domain routing helps in improving the allocation of IP addresses.

finlep [7]

Answer:

This is done for the simple reason of having more space to work on

Explanation:

This is done for the simple reason of having more space to work on. By clearing the command window and workspace you provide yourself with sufficient space to create new commands without the clutter of the previous commands. This also prevents your focus from shifting towards old commands and allows you to simply focus on the commands you are currently working on. This does not clear all variables from the script, it only clears the current screen but the previous commands can still be accessed by using the up-arrow key
