The SQL statement above could be interpreted as follows :

create table command is used to create a table named 'persons' with five columns which are labeled :

person I'd : whose data type is an integer

last name column with a variable character data type with maximum length of 255

first name column with a variable character data type with maximum length of 255

address column with a variable character data type with maximum length of 255

city column with a variable character data type with maximum length of 255

The VARCHAR data type is ideal since we expect the column values to be of variable length.

Explanation: Have a stupendous day! <3

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.

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;  

   }

};

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

Answer:

Explanation:

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

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.

Some popular examples of today's interpreters are:

Explanation:

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.

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.

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)

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);

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))  

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.

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.
