Identify the correct sequence of steps to change the font from Verdana to Arial.

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:

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

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

$\sigma_z = \sqrt{100}$

$\sigma_z = 10$

How do you erase data from your hard drive

fgiga [73]

The theory that your data is still recoverable by forensic analysis by well-financed governments, is based on a misunderstanding of a research paper from the mid 90s by Peter Gutmann, which looked at MFM floppy disks, not modern EPRML hard drives. Lifehacker describes the software that you will be using, Darik's Boot and Nuke, as "an open-source boot disk utility (read: works on nearly any computer) that supports a wide variety of disk wiping methods and operates from inside the computer's RAM, allowing it to scrub the disk thoroughly at a remove.

The router can deliver packets directly over interfaces 0 and 1 or it can forward packets to Routers R2, R3, or R4. Describe wha

ra1l [238]

Answer:

Following are the solution to this question:

Explanation:

In point A:

It applies the AND operation with the subnet-mask that is

$=128.96.39.00001010 \ \ AND \ \ 255.255.255.10000000 \\\\= 128.96.39.0000000 \\\\= 128.96.39.0 \\\$

This corresponds to a 128.96.39.0 subnet. This is why the router sent the packet to 0.

In point B:

It applies the AND operation with the subnet-mask that is $255.255.255.128$

$= 128.96.40.00001100\ AND \ 255.255.255.10000000 \\\\ = 128.96.40.0000000\\\\= 128.96.40.0$

This suits the 128.96.40.0 subnet. The router then sent R2 to the packet. The packet.

In point C:

It applies the AND operation with the subnet-mask that is $255.255.255.128$

$=128.96.40.10010111 \ AND \ 255.255.255.10000000 \\\\= 128.96.40.1000000\\\\= 128.96.40.128$

It applies the AND operation with the subnet-mask that is $255.255.255.192$

$= 128.96.40.10010111 \ AND \ 255.255.255.11000000 \\\\= 128.96.40.1000000 \\\\= 128.96.40.128\\$

All of the matches of its sublinks above.

Its default R4 router was therefore sent to the router by router.

In point D:

It applies the AND operation with the subnet-mask that is $255.255.255.192$

$= 192.4.153.00010001 \ AND \ 255.255.255.11000000\\\\ = 192.4.153.0000000 \\\\= 192.4.153.0 \\\\$

It matches the 192.4.153.0 subnet. It router has sent packet to R3 then.

In point E:

It applies the AND operation with the subnet-mask that is $255.255.255.128$

$= 192.4.153.01011010\ AND \ 255.255.255.10000000 \\\\= 192.4.153.0000000 \\\\= 192.4.153.0$

There, neither of the subnet inputs correlate with the ip address with the same subnet mask.

It applies the AND operation with the subnet-mask that is $255.255.255.192$

$=192.4.153.01011010\ AND \ 255.255.255.11000000 \\\\ = 192.4.153.0100000 \\\\= 192.4.153.64$

It does not correlate to the subnet entries for same subnet mask, and therefore neither of the entries matches their corresponding ip address entries.

Mask of the subnet. That packet would therefore be sent to the default R4 router by the router.

Answer:

Always back up your data. Prevention is the best protection.

Diversify your backups. You always want more than one backup system.

Encrypt sensitive data. Data is not always encrypted even when it's on a backup tape.

Address data security.

Use anti-virus and email security.
