Answer:

The answer is "Always true "

Explanation:

Following are the program to this question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

bool x=true;//defining bool variable x and assign value

bool y=false;//defining bool variable y and assign value

if(!(x || y) || (x || y))//use given condition with if block

{

   cout<<"True";//print true message

}

else//defining else block

{

   cout<<"false";//print false message

}

   return 0;

}

In the above code two bool variable is declared, that hold ture and false, and used in the given expression with the condition statement, that checks the given value. In the code the logical gate OR gate that always print the true value.

The sum of all the minterms of a boolean function of n variables is equal to 1.
Aleksandr-060686 [28]

The answers are as follows:

a) F(A, B, C) = A'B'C' + A'B'C + A'BC' + A'BC + AB'C' + AB'C + ABC' + ABC

= A'(B'C' + B'C + BC' + BC) + A((B'C' + B'C + BC' + BC)

= (A' + A)(B'C' + B'C + BC' + BC) = B'C' + B'C + BC' + BC

= B'(C' + C) + B(C' + C) = B' + B = 1


b) F(x1, x2, x3, ..., xn) = ∑mi has 2n/2 minterms with x1 and 2n/2 minterms

with x'1, which can be factored and removed as in (a). The remaining 2n1

product terms will have 2n-1/2 minterms with x2 and 2n-1/2 minterms

with x'2, which and be factored to remove x2 and x'2, continue this

process until the last term is left and xn + x'n = 1

Fed [463]

Answer:

total = 0

   total += bill

average = total / (4 * 3)

if average > 75:

   print("Average monthly bill is $" + str(average) + ". Too much water is being used")

if 25 <= average < 75:

   print("Average monthly bill is $" + str(average) + ". A typical amount of water is being used")

if average < 25:

   print("Average monthly bill is $" + str(average) + ". Thank you for conserving water")

Explanation:

*The code is in Python.

Create a for loop that asks the user to enter the bill for 4 quarters and calculate the total of the bills

Calculate the average monthly bill, divide the total by 12

The engineer will need to set the distance to 130 for the static link so that it becomes a floating static route.

<h3>What is Floating static routes?</h3>

This is known to be a static routes that is said to have a kind of administrative distance that is also known to be bigger than the administrative distance of any other static route or dynamic routes.

Note that the value 130 stands for the next most logical value, nd as such it is to know that the right route comes first in the steps for administrative distance.
