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. Write only valid account numbers to an output file, each on its own line. Save the application as ValidateCheckDigits.java.

State the items that will be examined when performing a binary search for Monkey,
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.

Explanation:
Create a program which reads in CSV data of Creatures and loads them into aHash Map. The key of this hash map will be the name of each creature. For your hash function, you can simply use the sum of all ASCII values. You can also come up with your own hash function. Your program should present a menu to the user allowing them to look up a creature by name. Additionally, create a function that allows the user to insert a new creature. This creature should be added to the existing hash map. If the name entered by the user already exists, DO NOT ADD IT TO THE HASH MAP. Simply report that the creature already exists. If the creature is unique and successfully added, report the calculated index value. Your hash array should start as size4. You will need to implement a rehashing function to maintain a load factor of 0.75. Collision resolution should be handled via separate chaining with linked lists.
Other Requirements
•Read in a CSV file from the command line when running the program.
•Convert the raw CSV data into the creature struct and add it to a HashMap
•Make sure you properly release all of your allocated memory.
•Format your code consistently.
•Function declarations, structs, and preprocess directives should be placed in a corresponding header file.
•Save your code for this problem ascreature_hash.(c|h).

We can cluster in one dimension as well as in many dimensions. In this problem, we are going to cluster numbers on the real line. The particular numbers (data points) are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100, i.e., the squares of 1 through 10. We shall use a k-means algorithm, with two clusters. You can verify easily that no matter which two points we choose as the initial centroids, some prefix of the sequence of squares will go into the cluster of the smaller and the remaining suffix goes into the other cluster. As a result, there are only nine different clusterings that can be achieved, ranging from {1}{4,9,...,100} through {1,4,...,81} {100}. We then go through a reclustering phase, where the centroids of the two clusters are recalculated and all points are reassigned to the nearer of the two new centroids. For each of the nine possible clusterings, calculate how many points are reclassified during the reclustering phase. Identify in the list below the pair of initial centroids that results in exactly one point being reclassified.
a) 36 and 64
b) 36 and 100
c) 4 and 16
d) 4 and 81
The list of the pair of initial centroids that results in exactly one point being reclassified is 36 and 64. The correct option is a.
What is the real line?A real axis, or a line with a set scale so that each real number corresponds to a distinct point on the line, is the most popular definition of "real line." The complex plane is a two-dimensional extension of the real line.
A cluster is a collection or grouping of items in a certain place. Mathematicians define a cluster as data accumulating around a single value, specifically a number. On a table or graph, a cluster can be seen visually where the data points are grouped together.
The numbers are 4, 9, 16, 25, 36, 49, 64, 81, and 100. In the real line, it will be 36 and 64.
Therefore, the correct option is a. 36 and 64.

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

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
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='')

Explanation:
The result is 55, which can also be verified using the formula:
(n)(n-1)/2 => 10*9/2 = 55
Explain how to back up a computer in five steps.
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.
Write a program that prompts the user to enter a series of numbers between 0 and 10 asintegers. The user will enter all numbers on a single line, and scores will be separatedby spaces. 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.
Answer:
The program in Python is as follows:
import collections
from collections import Counter
from itertools import groupby
import statistics
str_input = input("Enter a series of numbers separated by space: ")
num_input = str_input.split(" ")
numList = []
for num in num_input:
if(num.lstrip('-').isdigit()):
if num[0] == "-" or int(num)>10:
print(num," is out of bound - rejecting")
else:
print(num," is valid - accepting")
numList.append(int(num))
else:
print(num," is not a number")
print("Largest number: ",max(numList))
print("Smallest number: ",min(numList))
print("Range: ",(max(numList) - min(numList)))
print("Mode: ",end = " ")
freqs = groupby(Counter(numList).most_common(), lambda x:x[1])
print([val for val,count in next(freqs)[1]])
count_freq = {}
count_freq = collections.Counter(numList)
for item in count_freq:
print(item, end = " ")
lent= int(count_freq[item])
for i in range(lent):
print("#",end=" ")
print()
