Hi!

When someone repeatedly compares passwords to lists of common words, this is known as the dictionary attack.

We call it this because they are <em>literally </em>using a dictionary to attack you!

Hopefully, this helps! =)

Assume that x is a double variable that has been initialized. Write a statement that prints it out, guaranteed to have a decimal

Feliz [49]

Answer:

cout <<showpoint << x; is the statement which prints the decimal point, but without forcing scientific.

Explanation:

The showpoint function in c++ print the decimal point number without forcing scientific.The showpoint function set the showpoint format flag for the str stream in c++.

Following are the program in c++

#include<iostream> //header file

using namespace std; // namespace

int main() // main function

{

double x=90.67; // double variable

cout <<showpoint << x; // display x without forcing scientific

return 0;

}

Output

90.6700

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

Mnenie [13.5K]

Answer:

(1)Minterms complement = XYZ (2) Compliment of Minterms = Σm(0,1, 2 , 4 , 6) (3) (X+Y+Z) (4) Minimized SOP = Z + XY

Manterms = πM

Explanation:

Solution

Recall that:

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

(1) Canonical Disjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as minterms

In Minterm we assign 'I' to each uncomplimented variable and '0' to each complemented/complementary variable

For the given question stated we ave the following:

Minterms = XYZ, XYZ, XYZ, XYZ, XYZ.

(2) Canonical Conjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as maxterms.

In Maxterms we assign '0' to each uncomplimented variable and '1' to each complemented/complementary variable

Compliment of Minterms = Σm(0,1, 2 , 4 , 6)

Maxterms = πM

Note: Kindly find an attached copy of the complete solution to this question below.

For this problem, you will write a function standard_deviation that takes a list whose elements are numbers (they may be floats

Evgesh-ka [11]

Answer:

import math
def standard_deviation(aList):
sum = 0
for x in aList:
sum += x
mean = sum / float(len(aList))
sumDe = 0
for x in aList:
sumDe += (x - mean) * (x - mean)
variance = sumDe / float(len(aList))
SD = math.sqrt(variance)
return SD
print(standard_deviation([3,6, 7, 9, 12, 17]))

Explanation:

The solution code is written in Python 3.

Firstly, we need to import math module (Line 1).

Next, create a function standard_deviation that takes one input parameter, which is a list (Line 3). In the function, calculate the mean for the value in the input list (Line 4-8). Next, use the mean to calculate the variance (Line 10-15). Next, use sqrt method from math module to get the square root of variance and this will result in standard deviation (Line 16). At last, return the standard deviation (Line 18).

We can test the function using a sample list (Line 20) and we shall get 4.509249752822894

If we pass an empty list, a ZeroDivisionError exception will be raised.

Worms often try to disguise from where they are sending data by using a bogus ip addresses instead of using an authorized ip add

Katyanochek1 [597]

If the question is asking whether it is true or false, the answer is false because worms are not responsible for disguising when they are sending data by using bogus ip addresses but it is the Trojan horses in which they are the one responsible for misleading users from the true intent or the real data.
