Problem 8-4 A computer time-sharing system receives teleport inquiries at an average rate of .1 per millisecond. Find the probab
Sphinxa [80]

Answer:  a) 0.9980, b) 0.0013, c) 0.0020, d) 0.00000026, e) 0.0318

Step-by-step explanation:

Problem 8-4 A computer time-sharing system receives teleport inquiries at an average rate of .1 per millisecond. Find the probabilities that the number of inquiries in a particular 50-millisecond stretch will be:

Since we have given that

\lambda=0.1\ per\ millisecond=5\ per\ 50\ millisecond=5

Using the poisson process, we get that

(a) less than or equal to 12

probability=  P(X\leq 12)=\sum _{k=0}^{12}\dfrac{e^{-5}(-5)^k}{k!}=0.9980

(b) equal to 13

probability= P(X=13)=\dfrac{e^{-5}(-5)^{13}}{13!}=0.0013

(c) greater than 12

probability= P(X>12)=\sum _{k=13}^{50}\dfrac{e^{-5}.(-5)^k}{k!}=0.0020

(d) equal to 20

probability= P(X=20)=\dfrac{e^{-5}(-5)^{20}}{20!}=0.00000026

(e) between 10 and 15, inclusively

probability=P(10\leq X\leq 15)=\sum _{k=10}^{15}\dfrac{e^{-5}(-5)^k}{k!}=0.0318

Hence, a) 0.9980, b) 0.0013, c) 0.0020, d) 0.00000026, e) 0.0318

What is the rate of change for both of these tables. 25 pts
Rudiy27

Answer:

For the table on the left the rate of change is  22.8

For the table on the left the rate of change is -2

Step-by-step explanation:

The range of change is the slope. The slope can be found with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

<u>For the table on the left</u>

Choose two points. In this case you can choose (-1,-24), (4,90)

You can say that:

y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4

Substituting these values into the formula, you get:

m=\frac{-24-90}{-1-4}\\\\m=22.8

<u>For the table on the right</u>

Choose two points. You can choose (3,-6), (-6,12)

You can identify that:

y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6

Substituting these values into the formula, you get:

m=\frac{-6-12}{3-(-6)}\\\\m=-2

B, C, and F

Step-by-step explanation:

y = 1/2x

y = 1/2(4)

y = 2

y = 1/2x

y = 1/2(-2)

y = -1
