7. Consider the following statements: (i) If x and y are even integers, then x+y is an even integer. (ii) If x +y is an even integer, then and x and y are both even integers. (iii) If .c and y are integers and rº = y², then x = y. (iv) If r and y are real numbers and r
Answers
Statement (i) is true. This can be proven by considering the definition of an even integer, which is an integer that can be expressed as 2k for some integer k.
Therefore, if x and y are even integers, they can be written as 2a and 2b respectively, where a and b are integers. Thus, their sum would be 2a+2b=2(a+b), which is also an even integer.
Statement (ii) is false. Consider x=3 and y=1, then x+y=4 which is an even integer, but neither x nor y are even integers.
Statement (iii) is false. The equation rº = y² implies that r and y must both be non-negative real numbers. Therefore, there are infinitely many solutions to this equation, such as r=y=0 or r=y=1. Thus, x cannot be equal to y based solely on this equation.
Statement (iv) is true. If r is a rational number, then it can be expressed as a ratio of two integers: r=p/q where p and q are integers and q≠0. Similarly, y can be expressed as y=m/n where m and n are integers and n≠0. Substituting these expressions into the given equation, we get:
(p/q)² = (m/n)
Simplifying this equation, we get:
p²n²=q²m²
Since p, q, m, and n are all integers, this means that p²n² and q²m² are both perfect squares. Therefore, p²n² must be a multiple of q², which implies that p/q is also an integer. Hence, r is a rational number that can be expressed as a ratio of two integers and therefore a rational number.

Answers
The income statement shows that The Fabric Company generated $700,000 in revenue during the year ended 31 March 2016.
How to prepare the income statementTo prepare a proper income statement for The Fabric Company, we need to rearrange and group the information provided in the trial balance. Here is a possible format for the income statement:

Direct labor 24,000
Other direct expenses 16,000
Factory overheads 128,000
_______
Total Cost of Goods Manufactured 298,000
Cost of Goods Sold 473,700
_______
Gross Profit $226,300
Operating Expenses:
Office overheads 96,000
Operating Income $130,300
The income statement shows that The Fabric Company generated $700,000 in revenue during the year ended 31 March 2016.
However, to produce the goods sold, the company incurred significant costs related to the purchase of raw materials, direct labor, and other direct expenses, as well as indirect costs related to factory and office overheads.
After deducting the cost of goods sold from the revenue, we get the gross profit of $226,300. The operating expenses consist of the office overheads of $96,000, which are deducted from the gross profit to arrive at the operating income of $130,300.

which type of attack is wep extremely vulnerable to?
Answers
WEP is extremely vulnerable to a variety of attack types, including cracking, brute-force, IV (Initialization Vector) attack, and replay attack.
What is Initialization Vector?An Initialization Vector (IV) is a random number used in cryptography that helps to ensure the uniqueness and randomness of data used in an encryption process. The IV is typically used as part of an encryption algorithm, where it is combined with a secret key to encrypt a message. The IV is unique for each encryption session, and must be unpredictable and non-repeating. A good IV should not be reused across multiple encryption sessions, and it should be kept secret from anyone who does not have access to the decryption key. Without a good IV, a cryptographic system can be vulnerable to attacks such as replay attacks, where an attacker can gain access to the system by repeating an encrypted message.

The program outputs 11 numbers which are the first 11 Fibonacci numbers. The program uses a loop that goes through each number and checks if the sum of two values, "a" and "b", is equal to the loop variable "x".
What does this program do?
In the program, there is a "for" loop that iterates from 1 to 11. For each iteration, it inputs a number "n" and then calculates the value of "b" as the integer division of "n" by 10. If the condition "a + b == x" is satisfied, it outputs the value of "n".
Since the input values are the first 11 Fibonacci numbers (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89), they will all be output because the condition "a + b == x" is always true.

Answers
If you prematurely terminate an if statement with a semicolon, the compiler will-
b. Assume you are placing a null statement there
If you prematurely terminate an if statement with a semicolon, the compiler will assume that you are placing a null statement there. This means that the compiler will treat the semicolon as the body of the if statement, effectively making the if statement have an empty or no operation. The compiler will not display an error message in this case because a null statement is considered syntactically correct. However, it is important to note that this can lead to logical errors in your program, as the intended logic of the if statement may not be properly executed. It is essential to ensure that the if statement is correctly structured and that the semicolon is appropriately placed to avoid unintended behavior and maintain the desired logic flow in your code.
