Answer:

b. partition

Explanation:

The ranking functions make it easy to include a column in a result set that provides the sequential ranking number of each row within a partition. This is done as a subset of the built in functions that exist within the SQL Server. If the partition does not exists it can be the full result set. The order of the ranking within the partition is defined by the order clause of OVER.

Explanation:

Data is a raw fact, but information is a meaningful term.

Multiple data produce information

Data need to be processed toform information, information is understandable

The correct statement : Information is data that has been organized.

Hence correct statement is B .

Given, statements regarding data and information .

1. Data and information are two terms that can be used interchangeably.

This statement is not true.

While data and information are related, they are not the same thing. Data refers to raw facts, figures, or symbols that do not have any meaning on their own. On the other hand, information is the result of processing and organizing data in a meaningful way.

2. Information is data that has been organized.

This statement is true.

Information is created by organizing and processing data. When data is organized, categorized, or structured in a particular way, it becomes more meaningful and useful.

3. Information is data that has been sifted.

This statement is not entirely accurate.

While sifting or filtering data can be a part of the process of creating information, it is not the only step. Sifting implies removing unwanted or irrelevant data, which can help in narrowing down the focus, but it does not necessarily result in information.

4. Data is information that has been extracted.

This statement is not true.

Data is not the result of extracting information; rather, it is the raw material that is used to generate information. Data is collected, gathered, or obtained from various sources. It is then processed, organized, and analyzed to extract meaningful insights, which then become information.

Hence option B is correct .

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

[tex]rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)[/tex]

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

[tex]rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)[/tex]

[tex]rank(A) <n[/tex]

Then the system is consistent and has a unique solution.

E.g.

[tex]\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5 \end{matrix}\right.[/tex]

2) Writing it as Linear system

[tex]A=\begin{pmatrix}1 & -3 &-2 \\ 2& -4 &-3 \\ -3 &6 &8 \end{pmatrix}[/tex] [tex]B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}[/tex]

[tex]rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3[/tex]

3) The Rank (A) is 3 found through Gauss elimination

[tex](A|B)=\begin{pmatrix}1 & -3 &-2 &6 \\ 2& -4 &-3 &8 \\ -3&6 &8 &-5 \end{pmatrix}[/tex]

[tex]rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3[/tex]

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.

   print("The number is divisible") #print for true.

else:

   print("The number is not divisible") # print for false.

Output:

Explanation:

Final answer:

To test if a number is divisible by another, read both numbers and use modular division (% operator) to check for a zero remainder, ensuring the divisor is not zero to prevent errors.

Explanation:

Read two integers x and y from the user. If y is not equal to zero, use modular division to check if x % y equals zero. If the result is zero, then x is divisible by y, and the program should display an appropriate message stating this fact.

If y equals zero or if the modular division does not result in zero, appropriate messages should be displayed to indicate a division error or that the numbers are not divisible, respectively. The guard condition y != 0 is crucial as attempting to divide by zero would cause an error in the program.

// Pseudo code for the program

// Read x and y from the keyboard
Input x
Input y
// Check that y is not zero
target.y
// If y is not zero, perform the division
target.y
// Display the result
target.y

Answer:

if-elif-else                                            

Explanation:

In Python if condition is used to decide whether a statement or a block of statements is to be executed or not based on the condition, if the condition evaluates to true then the block of statements is executed and if the condition is false then it is not executed.

Sometimes we need to execute some other statement when the condition is false. For example

if (number1 <= number2)

print (number1,  "is the smallest")

Lets suppose we want to print another statement if this condition evaluates to false. If the condition gets false then the following message should be displayed:

print(number 2, "is the smallest")

For this purpose else statement is used along with if statement to execute the block of code when the if condition evaluates to false.

if (number1 <= number2)

print (number1,  "is the smallest")

else:

print(number 2, "is the smallest")

Now what if there are three numbers or more numbers to be compared in order to identify the smallest number from the given numbers. So in this case we have multiple options to be checked. else statement will not be enough a  for else there can be at most one statement. With if elif else multiple conditions can be checked and if any of the condition evaluates to true then its block of code is executed and if none of the condition is true then the last else statement will be executed.

For example:

if (number1 <= number2) and (number1 <= number3):

print (number1,  "is the smallest")

elif (number2 <= number1) and (number2 <= number3):

print (number1,  "is the smallest")

else:

print (number3,  "is the smallest")

In this example number1 is compared to number2 and number3. If both numbers are less than number1 then the program control goes to elif statement where number2 is compared to number1 and number3. if this condition is false too then the final else part will be printed which is that number3 is the smallest.

Take another example where there are more number of expressions to be checked.

val = 50

if (val == 40):  

   print ("value is 40")  

elif (val== 35):  

   print ("value is 35")  

elif (val == 25):  

   print ("value is 25")  

elif(val==15):

    print ("value is 15")  

else:  

   print ("value is not present")

This will output the else part value is not present, because none of the condition evaluates to true.

Final answer:

Python uses the 'elif' statement as a way to simplify nested decision structures, allowing programmers to add additional conditions without the need for excessive nesting.

Explanation:

Python provides a special version of a decision structure known as the elif statement, which makes the logic of the nested decision structure simpler to write. The elif statement stands for 'else if', and it allows for more succinct and readable conditional logic compared to using multiple if statements. For example:

if condition1:

   # Code block for first condition
elif condition2:

   # Code block for second condition
else:

   # Code block if neither condition is met

Without elif, you would have to nest an if statement within an else block, which could make the code harder to read and understand.

Answer: story board

Answer:

False

Explanation:

The statement is false because all statement after break statement are ignored but along with that control move out of loop to other instructions and  doesn't  perform next iteration of loop. Forexample:

for  (i=0;i<10;i++){

if(some condition)

break;

x=y;

y=z;

}

statement 1

statement 2

In above example after encountering break statement it will ignore statement after break plus it will not continue the next iteration and control move out of loop toward 'statement 1'

Answer:

Option b false

Explanation:

In programming, a break statement will terminate the loop and the program control will return to the statement after the loop. This means the loop won't prepare for the next iteration when a break statement is encountered.

One common use case of break statement is when we wish to terminate a linear search once the target number is found from an array. For example:

Since there is no point to continue the loop after the target number is found and therefore a break statement (Line 9) is included to terminate the loop.
