A company has three (3) components in a system and requires all three to be operational for 24 hours, Monday to Friday. Failure of component 1 occurs as follows: Monday = No failure. Tuesday = 5 a.m. to 7 a.m. Wednesday = No failure. Thursday = 4 p.m. to 8 p.m. Friday = 8 a.m. to 11 a.m. Directions: Using the scenario above, respond to the items below. Calculate the MTBF (Mean Time Between Failures) and MTTR of component 1. Show your steps of how you calculated the MTBF. Steps: MTBF = Total Uptime / Number Failures Total Uptime = (Number of Days Required Operational x Hours per Day Available) - Number of Hours Not Available MTTR = Total Downtime / Number of Failures What does the MTBF measurement tell you about the goal of having 99.999% uptime or Information Availability on system components?

Answers

Answer:

Following are the code to this question:

#include<stdio.h>//defining header file

//using namespace std;

int main()//defining main method

{

float MTBF, MTTR, Total_up;//defining float variable

Total_up = (4 * 24) - 9;//defining Total_up variable that calculate Total uptime value

MTBF = Total_up / 3.0;//defining MTBF variable that calculate its value

MTTR = 9 / 3;//defining MTTR that calculate its value

printf("\n The total value of MTBF: %f",MTBF);//print value with message

printf(" \n The total value of MTTR: %f ",MTTR);//print value with message

return 0;

}

Output:

The total value of MTBF: 29.000000  

The total value of MTTR: 3.000000  

Explanation:

In the above-given code, three float variable "MTBF, MTTR, and Total_up" is defined, in the next step the "Total_up" variable is defined, that holds a value to calculate its value.

In the next step, the "MTBF, and MTTR" variable is defined, and in the "MTBF" variable, it uses Total_up variable value to calculate its value and use the print method to print the "MTBF and MTTR" value.

Give a recursive definition of the set of positive integer powers of 3.That is the set {3,9,27,81,...}

Answers

Answer:

We have set A,

3 ∈ S

n*3 if n ∈ S

Explanation:

A recursion can be defined as a way of defining objects in terms of itself or as parts of itself.

Lets say we a set that is defined as A,

Then the recursive definition of the sets of positive integers with the powers of 3 in A is given as

3 ∈ S

n*3 if n ∈ S

This tells us that 3 is an element of S such that if n is an element of S then in general we would have n*3 to be an element of S

A technology that can help a student to increase his or her understanding of the vocabulary used in a classroom is called:_______

a. assistive instruction.
b. UDL technology.
c. hypertext software.
d. adaptive instruction.

Answers

Answer:

c. hypertext software.

Explanation:

In Computer science, a hypertext can be defined as textual informations that are being displayed on a computer system and these texts usually links to other informations (texts) that the user can easily have access to in real-time.

Basically, some developers include encyclopedias and dictionaries in their software database, which makes other necessary informations or contents easier and immediately accessible to the users through the use of hypertexts that is activated by pointing and clicking on the link with a mouse, keypress set or soft touching the screen.

Hence, a technology that can help a student to increase his or her understanding of the vocabulary used in a classroom is called hypertext software.

Explanation:

An algorithm is simply a list of steps to perform a defined action.

On 1, we described the most relevant steps to cook a simple cheeseburger.

Then on point 2, the same steps were taken and expanded with more detailed steps and conditions required to continue executing the following steps.

In computational terms, we used pseudo-code for the algorithm, since this is a list of actions not specific to any programming language.

Also we can say this is a structured programming example due to the sequential nature of the cooking process.

A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
printf("%0.2lf", yourValue);
Ex: If the input is:
5345
the output is:
2.67
Your program must define and call a function:
double StepsToMiles(int userSteps)
#include
/* Define your function here */
int main(void) {
/* Type your code here. */
return 0;
}

Answers

Answer:

The complete program is:

#include <stdio.h>

double StepsToMiles(int userSteps){

   return userSteps/2000.00;

}

int main(void) {

   int userSteps;

   printf("User Steps: ");

   scanf("%d",&userSteps);

   printf("%0.2f", StepsToMiles(userSteps));

   return 0;

}

Explanation:

This line defines the function

double StepsToMiles(int userSteps){

This returns the required output by dividing userSteps by 2000.

We used 2000.00 because we want it to return a floating point number

   return userSteps/2000.00;

}

The main begins here

int main(void) {

This declares userSteps as integer

   int userSteps;

This prompt user for input

   printf("User Steps: ");

This gets user input

   scanf("%d",&userSteps);

This calls the function and also returns the required output to 2 decimal places

   printf("%0.2f", StepsToMiles(userSteps));

   return 0;

}

Answer:

Coral Language Code

A pedometer treats walking 2,000 steps as walking 1 mile. Define a function named StepsToMiles that takes an integer as a parameter, representing the number of steps, and returns a float that represents the number of miles walked. Then, write a main program that reads the number of steps as an input, calls function StepsToMiles() with the input as an argument, and outputs the miles walked.

Output the result with four digits after the decimal point, which can be achieved as follows:

Put result to output with 4 decimal places

If the input of the program is:

5345

the function returns and the output of the program is:

2.6725

Your program should define and call a function:

Function StepsToMiles(integer userSteps) returns float numMiles

Explanation:

Function StepsToMiles(integer userSteps) returns float numMiles

  numMiles = userSteps / 2000.0

 

Function Main() returns nothing

  float result

  integer userSteps

  userSteps = Get next input

  result = StepsToMiles(userSteps)

  Put result to output with 4 decimal places

Assume you are part of the systems development team at a medium-sized organization. The database will enable sales reps to have more control over their customer information including up to date information on purchases, backorders, returns, and invoices. As a result of the system the company will be able to assign accounts to sales reps based on their expertise, the proximity to their other accounts, and experience level in the company. Commissions will also vary based on the types of products and services sold and the reps will be able to see special promotional programs in their regions. Part 1: you have just completed the database design portion of the systems design phase, and the project sponsor would like a status update. Assuming the project sponsor is a VP in the marketing department, with only a high-level understanding of technical subjects, how would you go about presenting the database design you have just completed?

A) 8 B) 64C) 128 D) 256

Answers

Answer:

D. 256

Explanation:

Given

[tex]Instructions = 8\ bit[/tex]

Required

Determine the maximum number of output

To get the required value, we make use of the following:

[tex]Maximum = 2^n[/tex]

Where n is the bits of the opcode.

i.e.

[tex]n = 8[/tex]

Substitute 8 for n in [tex]Maximum = 2^n[/tex]

[tex]Maximum = 2^8[/tex]

[tex]Maximum = 256[/tex]

5.14 Describe how the compare and swap() instruction can be used to provide mutual exclusion that satisfies the bounded-waiting requirement. (15 pts)

Answers

Answer:

Explained below

Explanation:

Compare and Swap(C&S) is simply an atomic operation whereby the compare and swap operations are automatically executed.

Now compare and Swap basically needs 3 arguments namely:

- 2 old values which we will label X and Y

- 1 new value which is written in X that we will call Z

Thus, we now have; C & S = {X, Y, Z}

To explain this well, let X be a variable where X has a value of 7.

Now, if a programmer gives a program me that X be multiplied by 2,then what C&S operation will do is;

I) Y = X where Y is a new variable.

II) Result = C&S(X, Y, X*7)

Variable X is global and this means that mere than one process and more than 1 thread can see the variable X.

Now, if a process named P1 wants multiply the variable X by 7 using C&S operation, it will first make a local copy of variable X (which in this case is now the new variable Y). After that it will atomically compare X & Y and if they are equal, it will replace X with 10X.

However, if they are not equal, P1 will re-read value of X into Y and carry of C&S instruction again.

Explanation:

There are two questions in this category and I don't know which of them you need; So, I answered both.

Question 1:

This line prompts user for age

currentage = int(input("Enter your age: "))

This line adds 10 to user input and prints the result

print("Your age in 10 years is "+str(currentage + 10))

Question 2:

This line prompts user for a whole number

userinput = int(input("Enter a whole number: "))

This line subtracts 5 from the whole number and prints the result

print(str(userinput)+" - "+str(5)+" = "+str(userinput - 5))
