For an array of size N what is the range of valid indices (or subscripts)?
Answer:
The valid range is 0 to N - 1
Explanation:
Required
Valid range of an array of size N
The index of an array starts from 0, and it ends at 1 less than the size.
Take for instance:
An array of size 4 will have 0 to 3 as its indices
An array of size 10 will have 0 to 9 as its indices
Similarly,
An array of size N will have 0 to N - 1 as its indices
the combination of hardware and software assembly accomplish some specific task as how...?
Answer:
A computing system can be referred to as a combination of hardware and software forms created to intentionally interact in specific ways such that the combination of both is able to achieve certain tasks.
Explanation:
Whilst a hardware refers to all the visible parts of the computing system such as the Visual Display Monitor or Screen, Keypads or Keyboards, Mouse and other input devices such as the camera, storage devices etc, the Software refers to intangible part - the logical instructions (machine language) which instructions the hardware on what or what not to do.

An array A[0..n - 2] contains `n-1` integers from 1 to `n` in increasing order. (Thus one integer in this range is missing.) Design an algorithm in $\Theta(\log n)$ to find the missing integer. Your algorithm should be given in **pseudo code**. For example, the array `A` could be `{1, 2, 3, 4, 6, 7, 8, 9, 10}` in which `5` is missing.
Answer:
I do not understand anything
Create a file named A10.java. Place all your code in this file. Create a publicstatic ArrayList of integers named intList.
Define a public static method addNumber(int i) that adds ito your list.
Exercise 2
Create a publicstatic HashMap of integers,integers namedintMap.
Define a public static method addPair(int i,int j) that adds i,jto your HashMap (make ithe key and j the value).
Explanation:
The file named as A10.java has been attached to this response. It contains the source code for the exercises. The source code contains comments explaining important parts of the code.
A few things to note;
i. To add an item to an arraylist, the add() method is used. For example to add an integer 7 to the arraylist named intList, simply write;
intList.add(7);
ii. To add an item to a hashmap, the put() method is used. The put method receives two parameters which are the key and value respectively. The key is a form of identifier used to store or retrieve a particular value in a hashmap. To store an integer 8 with a key of 5 in a hashmap named intMap, for example, simply write;
intMap.put(5,8);
A company manufactures televisions. The average weight of the televisions is 5 pounds with a standard deviation of 0.1 pound. Assuming that the weights are normally distributed, what is the weight that represents the 75th percentile?
Answer:
5.0674
Explanation:
Given that :
Mean, μ = 5 pounds
Standard deviation, σ = 0.1
Given that weight are normally distributed ;
From the Z table, the Zscore or value for 75th percentile weight is :
P(Z < z) = 0.75
z = 0.674
Using the relation :
Zscore = (x - μ) / σ
x = weight
0.674 = (x - 5) / 0.1
0.674 * 0.1 = x - 5
0.0674 = x - 5
0.0674 + 5 = x - 5 + 5
5.0674 = x
The weight which corresponds to the 75th percentile is 5.0674

which feature of organisations to manage needs to know about to build and use information system successfully
The correct answer to this open question is the following.
The feature of organizations to manage needs to know about to build and use information system successful is the following.
Managers of successful organizations should know that companies have hierarchies and different structures in which these companies are organized.
Every company use systems and procedures that could be specialized to the degree the company requires. For that system to function, they have to be perfectly interconnected to all the areas of the company. The goal: to maximize efficiency and accomplish the goals.
Systems and procedures should take into consideration the culture and diversity of the workplace. There are interest groups in every organization that have special characteristics and requirements that have to be taken into consideration to create a much better system.
Good managers must be aware of these elements, and the different roles, goals, management styles, tasks, incentives, and departmental structure of the company so the system can better serve the purpose of the entire organization.
Which one of these statements about digital signatures is true? A digital signature:
a. Is used to add a personal touch to e-mail messages.
b. Automatically encrypts the contents of an e-mail.
c. Is a scanned image of your real signature.
d. Is used to verify the identity of the sender of a message.
Answer:
A. Is used to add a personal touch to e-mail messages.Explanation:
A digital signature—a type of electronic signature—is a mathematical algorithm routinely used to validate the authenticity and integrity of a message (e.g., an email, a credit card transaction, or a digital document). ... Digital signatures are significantly more secure than other forms of electronic signatures.Determine the following information about each value in a list of positive integers.
a. Is the value a multiple of 7, 11, or 13?
b. Is the sum of the digits odd or even?
c. Is the value a prime number?
You should write a function named test7_11_13 with an integer input parameter and three type int output parameters (aka pointers) that send back the answers to these three questions. If the integer is evenly divisible by 7, 11 or 13, its respective output parameter should be set to 1, otherwise zero. Some sample input data might be:
104 3773 13 121 77 30751
Answer and Explanation:
Using Javascript:
test7_11_13(num){
If(num%7===0||num%11===0||num%13===0){
Console.log("yes it is a multiple of 7,11 or 13");
}
else{
Console.log("It is not a multiple of any of the numbers");
}
function(num){
var makeString= num.toString();
var splitString= makeString.split("");
var makeNumber= splitString.map(Number());
var New_number= makeNumber.reduce(function(a, b) {
return a+b};,0)
}
If(New_number%2===0){
Console.log("it's an even number");
}
else{
Console.log("it's an odd number")
}
If(num%2===0||num%3===0||num%5===0||num%7===0||num%11===0){
console.log("it's not a prime number");
}
else{
console.log("it's a prime number");
}
}
From the above we have used javascript if..else statements to test the conditions for each question and output the answer to the console using console.log(). In the last part for prime number, you could also choose to use else if statements(if,else if, else if) to test the value of the num parameter and output if it's a prime number.
You are the owner of a small business. In the last year, you have started to hire employees and you now have 5 employees. Each has his or her own personal computer and you have hired a consultant to establish a local area network for your business. You realize that you should draw up a user access agreement and a code of conduct for your employees. Which of the three documents listed below should you create first?
a. The user access agreement
b. The code of conduct
c. The professional association code of ethics
Answer:
a. The user access agreement
Explanation:
The first document that should be created would be the user access agreement. This is a document that holds all of the policies and guidelines that the employees of a company need to follow when using the companies equipment, software, or network. This includes behavior on the internet such as browsing specific sites, illegal activity, or personal hobbies during work hours, as well as offline such as using company hardware for personal gain. This is a document that is absolutely required for every company in order to protect the company from the consequences of certain employee activity.
Define a class Person that represents a person. People have a name, an age, and a phone number. Since people always have a name and an age, your class should have a constructor that has those as parameters.
Answer:
public class Person {
String name;
int age;
String phoneNumber;
public Person(String name, int age, String phoneNumber){
this.name = name;
this.age = age;
this.phoneNumber = phoneNumber;
}
}
Explanation:
The code above is written in Java.
The following should be noted;
(i) To define a class, we begin with the keywords:
public class
This is then followed by the name of the class. In this case, the name is Person. Therefore, we have.
public class Person
(ii) The content of the class definition is contained within the block specified by the curly bracket.
(iii) The class contains instance variables name, age and phoneNumber which are properties specified by the Person class.
The name and phoneNumber are of type String. The age is of type int. We therefore have;
String name;
int age;
String phoneNumber;
(iv) A constructor which initializes the instance variables is also added. The constructor takes in three parameters which are used to respectively initialize the instance variables name, age and phoneNumber.
We therefore have;
public Person(String name, int age, String phoneNumber){
this.name = name;
this.age = age;
this.phoneNumber = phoneNumber;
}
(v) Notice also that a constructor has the same name as the name of the class. In this case, the constructor's name is Person.
Answer:
The class and constructor in C++ is as follows:
class Person {
public:
string name; int age; int phone;
Person (string x, int y) {
name = x; age = y;
}
};
Explanation:
This defines the class
class Person {
The specifies the access specifier
public:
This declares the attributes; name, age and phone number
string name; int age; int phone;
This defines the constructor for the name and age
Person (string x, int y) {
This gets the name and age into the constructor
name = x; age = y;
}
};
Suppose users share a 3 Mbps link. Also suppose each user requires 150 kbps when transmitting, but each user transmits only 10 percent of the time. (See the discussion of packet switching versus circuit switching in Section 1.3.)
a. When circuit switching is used, how many users can be supported?
b. For the remainder of this problem, suppose packet switching is used. Find the probability that a given user is transmitting.
c. Suppose there are 120 users. Find the probability that at any given time, exactly n users are transmitting simultaneously. (Hint: Use the binomial distribution.)
d. Find the probability that there are 21 or more users transmitting simultaneously.
Answer:
a) 20 users
b) 0.1 or 1/10
c) P ( X = n ) = [tex]^{120}C_{n} ( 0.10 )^n (0.9)^{120-n}[/tex]
d) 0.008
Explanation:
Given data:
Link shared by users = 3 Mbps
each user requires ; 150 kbps
percentage transmitted by each user = 10%
a) Determine the number of users can be supported
number of users = 3 Mbps / 150 kbps = 3000 / 150 = 20 users
b) P( user is transmitting )
given that percentage transmitted by each user = 10%
since packet switching is used ; P ( user is transmitting ) = 10% = 0.1
c) P ( n users are transmitting simultaneously )
let the number of users ( i.e. N ) = 120
number transmitting = n
P ( user is transmitting ) = 0.10
using Binomial distribution
P ( X = n ) = [tex]^{N}[/tex]Cₙ ( P )ⁿ ( 1 - P )^[tex]^{N-n}[/tex]
= [tex]^{120}C_{n} ( 0.10 )^n (0.9)^{120-n}[/tex]
d) P( X ≥ 21 transmitting simultaneously )
P ( X = n ) = [tex]^{120}C_{n} ( 0.10 )^n (0.9)^{120-n}[/tex]
Therefore ; P( X ≥ 21 ) = 1 - P( X ≤ 20 )
= 1 - BINOMDIST(20,120,0.1,1) ( excel function )
∴ P( X ≥ 21 ) = 1 - 0.992059 ≈ 0.008

Ten examples of an interpreter
Answer:
Some popular examples of today's interpreters are:
Interpreter of PythonInterpreter for RubyPerl performerInterpreter for PHPMATLAB UCSD PascalExplanation:
An interpreter executes the commands directly in an object code or a machine code, written in a program or a scripting language.
The Interpreter can be referred to as system software that can read and execute the programme instead of interpreting programmes. This interpretation includes high-level source code, pre-compiled programmes and scripts.
It is important to note that the interpreter translates programme by programme line, meaning that one statement is translated on one go. This feature makes it easy for programmers to check any line on debugging but slows the whole programme running time.
1. Briefly explain the various types of models used in software Engineering with benefits and limitations for each
Answer:
The Software Model represents the process abstractly. The different activities involved in developing software products are present in each phase of the software model. The order for each stage to be executed is also specified.
Explanation:
Waterfall model:-
Benefits
Implementing the waterfall model is very easy and convenient.
It is very useful for implementing small systems.
Limitations
If some of the changes are made at certain phases, it may create confusion.
First, the requirement analysis is performed, and sometimes not all requirements can be expressly indicated in the beginning.
Spiral model:-
Benefits
The working model of the system can be quickly designed through the construction of the prototype.
The project can be refined by the developer and the user during the development phase.
Limitations
If customer communication is not good or proper, the result is total project failure or project failure which could lead to project comission.
6.23 LAB: Convert to binary - functions Instructor note: This is a lab from a previous chapter that now requires the use of a function. If you weren't able to solve it before, think of this as a new opportunity. Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The function integer_to_reverse_binary() should return a string of 1's and 0's representing the integer in binary (in reverse). The function reverse_string() should return a string representing the input string in reverse. def integer_to_reverse_binary(integer_value) def reverse_string(input_string)
Answer:
The program in Python is as follows:
import math
def integer_to_reverse_binary(integer_value):
remainder = ""
while integer_value>=1:
remainder+=str(integer_value % 2)
integer_value=math.floor(integer_value/2)
reverse_string(remainder)
def reverse_string(input_string):
binaryOutput=""
for i in range(len(input_string)-1,-1,-1):
binaryOutput = binaryOutput + input_string[i]
print(binaryOutput)
integer_value = int(input("Enter a Number : "))
integer_to_reverse_binary(integer_value)
Explanation:
This imports the math module
import math
This defines the integer_to_reverse_binary function
def integer_to_reverse_binary(integer_value):
This initializes the remainder to an empty string
remainder = ""
This loop is repeated while the integer input is greater than or equal to 1
while integer_value>=1:
This calculates the remainder after the integer value is divided by 2
remainder+=str(integer_value % 2)
This gets the floor division of the integer input by 2
integer_value=math.floor(integer_value/2)
This passes the remainder to the reverse_string function
reverse_string(remainder)
The reverse_string function begins here
def reverse_string(input_string):
This initializes the binaryOutput to an empty string
binaryOutput=""
This iterates through the input string i.e. the string of the remainders
for i in range(len(input_string)-1,-1,-1):
This reverses the input string
binaryOutput = binaryOutput + input_string[i]
This prints the binary output
print(binaryOutput)
The main begins here
This gets input for integer_value
integer_value = int(input("Enter a Number : "))
This passes the integer value to the integer_to_reverse_binary function
integer_to_reverse_binary(integer_value)
Given 4 floating-point numbers. Use a string formatting expression with conversion specifiers to output their product and their average as integers (rounded), then as floating-point numbers. Output each rounded integer using the following: print('{:.0f}'.format(your_value)) Output each floating-point value with three digits after the decimal point, which can be achieved as follows: print('{:.3f}'.format(your_value))
Answer:
The program is as follows:
prod = 1
isum = 0
for i in range(4):
num = float(input())
prod*=num
isum+=num
avg = isum/4
print('{:.0f}'.format(prod))
print('{:.3f}'.format(avg))
Explanation:
This initializes the product to 1
prod = 1
..... and sum to 0
isum = 0
The following iteration is repeated 4 times
for i in range(4):
Get input for each number
num = float(input())
Calculate the product
prod*=num
Add up the numbers
isum+=num
This calculates the average
avg = isum/4
Print the products
print('{:.0f}'.format(prod))
Print the average
print('{:.3f}'.format(avg))

Use the following to calculate the acid-test ratio. (Round your answer to two decimal places.) Cash: $100,000 Short-term investments: 17,000 Net current receivables: 250,000 Inventory: 330,000 Total current liabilities: 760,000 O 0.92 5.88 O 0.79 0.48
Answer: 0.48
Explanation:
The acid test ratio will be calculated as:
Cash = $100,000
Add: Short term investments = $17,000
Add: Net Current Receivables = $250,000
Total Assets = $367,000
/ Total Current Liabilities = $760,000
Acid Test Ratio will now be:
= Total Assets / Total Liabilities
= $367000/$760000.
= 0.48
Therefore, the acid test ratio is 0.48.

For minimization problems, the optimal objective function value to the LP relaxation provides what for the optimal objective function value of the ILP problem?
Answer:
A lower bound on the optimal integer value.
Explanation:
The question is poorly typed. The original question requires the optimal solution of the objective function of a minimization problem
I will answer this question base on the above illustration.
When an objective function is to be minimized, it means that the objective function will take the feasible solution with the least value.
The least value are often referred to as the lower bound.

Answer:
I think the third one (or the one with monkeys).
Explanation:
2+2 does not equal 5, so the if then statement is void because both parts are wrong.
1+1 does not equal 3 even if 2+3 =5, so it is not the second answer.
3+1 does not equal 3, but monkeys do fly and it is an or option, so when one of them is correct in an or, it is correct.
