Answer:

How to convert binary to decimal ?

It consists of digits from 0 to 9. Binary to decimal conversion can be done in the simplest way by adding the products of each binary digit with its weight (which is of the form - binary digit × 2 raised to a power of the position of the digit) starting from the right-most digit which has a weight of 20.

what is digital and analogue?

In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape.In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device.

Using Sequential Search on an array of size n, the search key is definitely present in the array. The probability of matching th

MissTica

Answer:

(11n-5) / 12 is correct answer.

Explanation:

The Probability that key will match to nth term = 1/2

The Probability that key will match to n-1th term = 1/3

As all other probabilities are equal

The Total Probability that key matches to any of 1 to n-2 index = 1 - 1/2 - 1/3 = 1/6

The Probability that key matches to any of 1 to n-2 index = (1/6) / n-2 = (1/6)* (n-2))

Let P(i) = Probability that key matches to ith index.

The Average time complexity = 22 i=1 P(i) * i

The Average time complexity = 1/(6(n-2) * ( sum of 1 to n-2 ) + (n-1) / 3 + n/2

The Average time complexity = 1/(6(n-2) * ( n-2)*(n-1) / 2 + ( n-1) / 3 + n/2

The Average time complexity = 1/6 * (n-1)/2 + (n-1)/3 + n/2

The Average time complexity = (n-1)/12 + (n-1)/3 + n/2

The Average time complexity = (n-1 + 4 * n - 4 * 1 +6 * n)/12

The Average time complexity = 11n-5 / 12

so (11n-5) / 12 is correct answer.

The IPv4 address scheme has enough IP addresses to give every blade of glass in the world its own unique IP. True False

Andrew [12]

Answer:

False

Explanation:

IPv4 address are composed of four octets (8 bit numbers), ranging from <em>0.0.0.0 to 255.255.255.255</em>

All those 32 bits, in decimal notation, can form a total of

$2^{32} = 4,294,967,296$ different addresses.

Being more than 4 billion addresses and ignoring that some addressesare reserved for special uses, even present human population almost doubles that number.

So it is safe to state that IPv4 addresses is <u>not </u>enough to give every blade of grass its own IP.

Find the simple interest Jay owes on a five-year student loan of $48,000 with an annual interest rate of 5%.

borishaifa [10]

Use the equation I=prt where interest = principal times rate times time.

Fill it out, it becomes I= 48000(.05)(5)

I= 12000
