Answer:
Explanation:
1. Decide what to back up
If you've stored anything valuable on your hard drive , you'll need to back that up yourself.
2. Choose backup media
You'll need to store your backup on a separate form of digital media - such as Go-ogle Drive, One Drive for Business or an external hard drive
3. Back up your data
The backup method will vary depending on your choice of software and operating system Once that's done, schedule regular future backups.
4. Store it safely
You don't want to lose your PC and your backup. So, be smart and keep your backup somewhere safe.
5. Check that it works
Errors and technical glitches can happen without you even noticing. You may only find out later when you actually need to use that data that something went wrong. Avoid the worry by checking your backups once in a while and confirming that the data is being properly backed up.

Which of the following statements should be avoided when developing a mission statement?
The how-to statements.
Describe the “who, what, and where” of the organization.
Be brief, but comprehensive.
Choose wording that is simple.
Answer: The how-to statements
Explanation:
The mission statement is simply a short summary of the purpose of a company. It is the guideline on how a company will operate. The mission statement states the reason for the existence of a company, products sold or service rendered and the company's goals.
The mission statement should be brief but comprehensive, consist of simple words and describe the “who, what, and where” of the organization.
Therefore, the incorrect option based on the explanation above is "The how-to statements". This shouldn't be part of the mission statement.

Complete the Rectangle class. It has a rectangle's length and width as class variables and contains methods to compute its area and perimeter. If either parameter is negative, the method should calculate based on its absolute value. Then, you'll take user inputs to create an instance of Rectangle. For example, if you provide the input -13 7 You should receive the output Perimeter = 40.0 Area = 91.0 Note: It is NOT necessary to use the math module to calculate absolute value, though you may if you want. 298800.1775650.qx3zqy7 LAB ACTIVITY 28.4.1: Final Exam 2021 - Problem 4 of 6 0/10 main.py Load default template... 1 class Rectangle: _init__(self, length, width): # your code here 4 5 def area (self): 6 # your code here 7 8 def perimeter (self): 9 # your code here 10 11 if _name__ == '__main__': 12 1 = float(input) 13 w = float(input) 14 r = Rectangle(1, w) 15 print("Perimeter =', r.perimeter()) 16 print('Area =', r.area(), end='')|
Answer:
The complete program is as follows:
class Rectangle:
def __init__(self, length, width):
self.width = abs(width)
self.length = abs(length)
def area(self):
area = self.length * self.width
return area
def perimeter (self):
perimeter = 2 * (self.length + self.width)
return perimeter
if __name__ == '__main__':
l = float(input(": "))
w = float(input(": "))
r = Rectangle(l, w)
print('Perimeter =', r.perimeter())
print('Area =', r.area(), end='')
Explanation:
This defines the class:
class Rectangle:
This gets the parameters from maiin
def __init__(self, length, width):
This sets the width
self.width = abs(width)
This sets the length
self.length = abs(length)
The area function begins here
def area(self):
Calculate the area
area = self.length * self.width
Return the calculated area back to main
return area
The perimeter function begins here
def perimeter (self):
Calculate the perimeter
perimeter = 2 * (self.length + self.width)
Return the calculated perimeter back to main
return perimeter
The main begins here
if __name__ == '__main__':
This gets input for length
l = float(input(": "))
This gets input for width
w = float(input(": "))
This passes the inputs to the class
r = Rectangle(l, w)
This prints the returned value for perimeter
print('Perimeter =', r.perimeter())
This prints the returned value for area
print('Area =', r.area(), end='')

The syntax of an update statement is:
UPDATE table-name SET column-name = 'value' WHERE column-name = 'value'
Using the above syntax, the right statements is as follows:
UPDATE song SET title = 'With Or Without You' WHERE song_ID = 200The above sets the title to 'With Or Without You' where song id is 200
UPDATE song SET artist = 'Aritha Franklin' WHERE song_ID = 300
The above sets the artist to 'Aritha' where song id is 300
UPDATE song SET release_year = 2021 WHERE release_year > 1990The above sets the release year to '2021' for all release year greater than 1990

which is not in the list.
The items that will be examined when performing a binary search for monkeys are Antelope, Baboon, Cheetah, Elephant, and Giraffe in the first half of the cycle.
What is binary search?
A search algorithm known as binary search in computer science, also known as half-interval search, logarithmic lookup, or binary chop, asserts to have discovered the location of a target value within a sorted array.
The target value is compared to the middle element of the array using binary search. A successful approach for finding an item in a sorted list of elements is binary search.
Therefore, in the first half of the cycle, the following objects will be looked at when conducting a binary search for monkeys: antelope, baboon, cheetah, elephant, and giraffe.

You cannot assume the user will supply valid integers, nor can you assumethat they will enter positive numbers, so make sure that you validate your data. You donot need to re-prompt the user once they have entered a single line of data. Once youhave collected this data you should compute the following: • The largest value • Thesmallest value • The range of values • The mode (the value that occurs the most often) •A histogram that visualizes the frequency of each number Here’s a sample running of theprogram.

Create a game that rolls two dies (number from 1 to 6 on the side) sequentially for 10 times (use loop). If at least once out of 10 times the sum of two random numbers is equal to 10, you win, else you loose. You will need to get your own method getRandom(int n) that generates a random number, see below (you can modify it as needed), a loop, and IF statement in the loop that checks if a sum of two random numbers is 10 or not.
Please start your program as follows, similar to what we did in class:
import java.util.Random;
public class UseRandom{
//your method getRandom() is here below, n is a range for a random number from 0 to n
public int getRandom(int n)
{
Random r=new Random();
int rand=r.nextInt(n);
return rand;

The speed density fuel injection system uses the blank sensor as the primary sensor as the primary sensor to determine base pulse width
A. Map
B TP
C Maf
D baro
Answer:
A) Map
Explanation:
All gasoline (petrol) fuel systems need ways or method that will be calculating amount of the air that is entering the engine.This is true as regards mechanical fuel injection, carburetors and electronic fuel injection.Speed density system fall under one of this method. "Speed" in this context means the speed of the engine while "density" means density of the air. The Speed is been measured using the distributor, crankshaft position sensor could be used here. The Density emerge from from measuring of the air pressure which is inside the induction system, using a typical "manifold absolute pressure" (MAP) sensor as well as air temperature sensor. Using pieces of information above, we can calculate
mass flow rate of air entering the engine as well as the correct amount of fuel can be supplied. With this system,
the mass of air can be calculated. One of the drawback if this system is that
Any modification will result to incorrect calculations. Speed-Density can be regarded as method use in estimation of airflow into an engine so that appropriate amount of fuel can be supplied as well as. adequate spark timing. The logic behind Speed-Density is to give prediction of the amount of air ingested by an engine accurately during the induction stroke. Then this information could now be used in calculating how much fuel is required to be provided, This information as well can be used in determining appropriate amount of ignition advance. It should be noted The speed density fuel injection system uses the Map sensor as the primary sensor to determine base pulse width

Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5.
