Point C is on line segment \overline{BD} BD . Given CD=x,CD=x, BC=5x-5,BC=5x−5, and BD=2x+7,BD=2x+7, determine the numerical len

NARA [144]

Answer:

$CD = 3$

Step-by-step explanation:

Given

$CD = x$

$BC = 5x - 5$

$BD = 2x + 7$

Required

Determine CD

Since, C is a point on BD, the relationship between the given parameters is;

$BD = BC + CD$

Substitute the values of BD, BC and CD

$2x + 7 = 5x - 5 + x$

Collect Like Terms

$2x - 5x - x = -5 - 7$

$-4x = -12$

Divide both sides by -4

$\frac{-4x}{-4} = \frac{-12}{-4}$

$x = 3$

To determine the length of CD;

Substitute 3 for x in $CD = x$

Hence;

$CD = 3$

A message source M of a digital communication system outputs a word of length 8 characters, with the characters drawn from the t

marysya [2.9K]

Answer:

The probability that M produces a word that looks like a byte is $(\frac{2}{3})^8$ .

Step-by-step explanation:

It is given that a message source M of a digital communication system outputs a word of length 8 characters.

The characters drawn from the ternary alphabet {0,1,2}, and all such words are equally probable.

Total possible outcomes is

$3\times 3\times 3\times 3\times 3\times 3\times 3\times 3=3^8$

We need to find the probability that M produces a word that looks like a byte (i.e., no appearance of ‘2’). It means only 0 and 1 are included in the word.

Total favorable outcomes is

$2\times 2\times 2\times 2\times 2\times 2\times 2\times 2=2^8$

The formula for probability is

$p=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

$p=\frac{2^8}{3^8}$

$p=(\frac{2}{3})^8$

Therefore the probability that M produces a word that looks like a byte is $(\frac{2}{3})^8$ .
