What command is used to generate an RSA key pair?
Leokris [45]

Answer:

D) crypto key generate rsa

Explanation:

In cryptography, the RSA refers to Rivest–Shamir–Adleman. This is an algorithm used for encrypting and decrypting messages in computers thereby ensuring secured transmission of data. In order to generate an RSA key pair, you will use the command crypto key generate rsa while in the global configuration mode. This command has the following syntax:

crypto key generate rsa [general-keys| usage-keys| signature| encryption] [<em>labelkey-label</em>] [exportable] [modulus <em>modulus-size</em>] [storage <em>name of device</em>:][redundancy][on <em>name of device</em>:],

with each parameter having its description

How many 1000-Watt lights can be plugged into a standard 120-Volt, 15-Amp outlet? (Hint: W/V=A) *
Licemer1 [7]

Answer:

There are up to 12 lights and or plugs on that circuit. A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit.

Fifty-three percent of U.S households have a personal computer. In a random sample of 250 households, what is the probability th
aleksley [76]

Answer:

The correct Answer is 0.0571

Explanation:

53% of U.S. households have a PCs.

So, P(Having personal computer) = p = 0.53

Sample size(n) = 250

np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10

So, we can just estimate binomial distribution to normal distribution

Mean of proportion(p) = 0.53

Standard error of proportion(SE) =  \sqrt{\frac{p(1-p)}{n} } = \sqrt{\frac{0.53(1-0.53)}{250} } = 0.0316

For x = 120, sample proportion(p) = \frac{x}{n} = \frac{120}{250} = 0.48

So, likelihood that fewer than 120 have a PC

= P(x < 120)

= P(  p^​  < 0.48 )

= P(z < \frac{0.48-0.53}{0.0316}​)      (z=\frac{p^-p}{SE}​)  

= P(z < -1.58)

= 0.0571      ( From normal table )
