Suppose a program takes 1000 machine instructions to run from start to end, and can do that in 10 microseconds when no page faul

ts occur. How long will this same program take if 1 in every 100 instructions has a page fault and each page fault takes 100 milliseconds to resolve?

Answer:

(10^6 + 9.9)

Explanation:

Given:

Total number of machine instructions = 1000

Number of page fault in 100 instructions = 1

Number of page faults in 1000 instructions = 10

Time to serve one page fault = 100 milliseconds

Time to serve ten page faults = 100*10 milliseconds = 1000 milliseconds = 10^6 Microseconds

Number of instructions without any page fault = 1000 - 10 = 990

Time required to run 1000 instructions = 10 Microseconds

So, time required to run 990 instructions = (10*(990/1000)) Microseconds = 9.9 Microseconds

So, the total time required to run the program = (10^6 + 9.9) Microseconds

 if bag_ounces<3:

    print("Too Small")

 elif bag_ounces>10:

   print("Too Large")

 else:

   total = 6*bag_ounces

   print('{} seconds'.format(total))

Explanation:

Using Python programming language

The function is defined to accept a single parameter

A blood bank maintains two tables - DONOR, with information about people who are willing to donate blood and ACCEPTOR, with info
Kipish [7]

Answer:

The sql query is given below.

Since we need to count of males and females for a particular blood group, we put xxx for the blood group.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors,

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Explanation:

The clauses in the query are as follows.

1. SELECT: all the columns required in the output are put in this clause.

2. FROM JOIN ON: the table(s) from which the above columns are taken are put in this clause.

3. WHERE: any condition required to filter the output is put in this clause.

The query is explained below.

1. Find the number of male donors. Number of anything can be found using COUNT() function. A query is required since gender is included in deciding the type of donor.

2. The query is defined to find number of male donors as follows.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "M%"; )

3. In the previous query, LIKE operator is used since it is not defined what value is stored for male donors.

4. Similarly, the query to find the number of female donors is formed.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "F%"; )

5. Next, the final query is formed as follows.

SELECT: both COUNT() functions will come here.

FROM: table name

WHERE: specific blood group will be put here

GROUP BY: this clause is optional and is not used in this query.

HAVING: this clause is optional and is not used in this query.

6. The query after putting all clauses is shown below.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%"),

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%")

FROM DONOR

WHERE BG = xxx;

7. Alias is used in the above query for each column to get the final query.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors, COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Create a Visual Logic flow chart with four methods. Main method will create an array of 5 elements, then it will call a read met
pogonyaev

Answer:

See explaination

Explanation:

import java.util.Scanner;

public class SortArray {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc = new Scanner(System.in);

System.out.println("Enter Size Of Array");

int size = sc.nextInt();

int[] arr = new int[size]; // creating array of size

read(arr); // calling read method

sort(arr); // calling sort method

print(arr); // calling print method

}

// method for read array

private static void read(int[] arr) {

Scanner sc = new Scanner(System.in);

for (int i = 0; i < arr.length; i++) {

System.out.println("Enter " + i + "th Position Element");

// read one by one element from console and store in array

arr[i] = sc.nextInt();

}

}

// method for sort array

private static void sort(int[] arr) {

for (int i = 0; i < arr.length; i++) {

for (int j = 0; j < arr.length; j++) {

if (arr[i] < arr[j]) {

// Comparing one element with other if first element is greater than second then

// swap then each other place

int temp = arr[j];

arr[j] = arr[i];

arr[i] = temp;

}

}

}

}

// method for display array

private static void print(int[] arr) {

System.out.print("Your Array are: ");

// display element one by one

for (int i = 0; i < arr.length; i++) {

System.out.print(arr[i] + ",");

}

}

}
