Answer:

115

Step-by-step explanation:

set up the equation to find x:

GFN+NFG=GFE

(4x+10)+(14x+3)=157

calculate for x

you'll get x=8

put 8 into NFE

14(8)+3=115

What is the slope and y intercept of this graph
castortr0y [4]
The y-intercept is the value of "y" when x=0.

Answer. y-intercept= 4

Given two points (x₁,y₁) and (x₂,y₂) the slope passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)

For example :
we can consider the points (0,4) and (4,0)
m=(0-4)/(4-0)=-4/4=-1

Answer the slope of this line would be m=-1

When network cards are communicating, bits can occasionally be corrupted in transmission. Engineers have de- termined that the n
ycow [4]

Answer:

a) 11.40% probability of 5 bits being in error during the transmission of 1 kb

b) 11.60% probability of 8 bits being in error during the transmission of 2 kb

c) 0.01% probability of no error bits in 3kb

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the giveninterval.

Poisson distribution with mean of 3.2 bits/kb (per kilobyte).

This means that \mu = 3.2kb, in which kb is the number of kilobytes.

(a) What is the probability of 5 bits being in error during the transmission of 1 kb?

This is P(X = 5) when \mu = 3.2

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 5) = \frac{e^{-3.2}*3.2^{5}}{(5)!} = 0.1140

11.40% probability of 5 bits being in error during the transmission of 1 kb

(b) What is the probability of 8 bits being in error during the transmission of 2 kb?

This is P(X = 8) when \mu = 2*3.2 = 6.4

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 8) = \frac{e^{-6.4}*6.4^{8}}{(8)!} = 0.1160

11.60% probability of 8 bits being in error during the transmission of 2 kb

(c) What is the probability of no error bits in 3kb?

This is P(X = 0) when \mu = 3*3.2 = 9.6

Then

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 0) = \frac{e^{-9.6}*9.6^{0}}{(0)!} = 0.0001

0.01% probability of no error bits in 3kb
