Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

$y = mx + b$

where m=3 is the slope .

We substitute the slope to get:

$y = 3x + b$

We substitute the point to find b.

$- 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4$

The equation of the straight line is:

$y = 3x + 4$

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 $(\frac{2}{3})^8$ .

Which of these strategies would eliminate a variable in the system of equations?

ira [324]

Answer:

B) Subtract the bottom equation from the top equation

C) Add the equations.

Step-by-step explanation:

We have to eliminate a variable in the system of equations

6x + 5y = 1 . (1) and

6x - 5y = 7 (2) and,

Since the y-term on both the equations are the same but opposite in sign, therefore the strategy to eliminate y variable from the system of equations (1) and (2) is to add the equations. (Answer)

Again, the x-terms are the same and with a similar sign, therefore, by subtracting the bottom equation from the top equation we can also eliminate the x-variable. (Answer)
