Answer:
3 times faster
Explanation:
The full form of RMS is Rivest–Shamir–Adleman. It refers to the public key crypto-system which is mainly used for securing the data transmission. It is one of the oldest algorithm.
The time taken bu modular squaring is 75 percent of the time required by the modular multiplication. Therefore, one encryption works three times quicker on an average if the short exponent of [tex]$e=2^{16}+1$[/tex] is used instead of the 2048 bit public key.

You're not adding your temperature to the total so total will always be 0. Do something like this:
total += float(input("Enter Temperature: "))
You can directly add the user entered value without creating an extra variable.

10. In cell R8, enter a formula using the AVERAGEIF function to determine the average number of post-secondary years for students who have been elected.
Answer:
On cell R8, type in the formula "=AVERAGEIF(M2:M31,"Elected",D2:D31)".
Explanation:
Microsoft Excel is a spreadsheet application developed by Microsoft as a part of the office package, used for statistical analysis of data. It has several tools used for this purpose.
The AVERAGEIF function is used to give the average of numeric column based on a condition. The formula above uses the word 'Elected' in the M column to calculate the average of numbers in the D column.
The formula to enter in cell R8 is =AVERAGEIF(M2:M31,"Elected",D2:D31)
The AVERAGEIF function is used to calculate the average of a range of numbers if a certain condition is true.
From the complete question,
The range is M2 to M31
The condition is to check is the students in range D2 to D31 have been elected
The syntax of the AVERAGEIF function
=AVERAGEIF(range,criteria,average_range)
So, the formula to enter in cell R8 is =AVERAGEIF(M2:M31,"Elected",D2:D31)

Normalization works through a series of stages called normal forms. For most purposes in business database design, three stages are as high as you need to go in the normalization process.
Normalization is the process of organizing and structuring a database in a way that reduces redundancy, dependency, and anomalies while improving data integrity and efficiency. It involves applying a set of rules and guidelines to design a database schema that minimizes data redundancy and ensures data consistency.
The primary goal of normalization is to eliminate data anomalies such as insertion, update, and deletion anomalies, which can occur when data is duplicated or dependencies between data elements are not properly managed.

what's a good online University to attended for cyber security certificate.?
Answer:
If your in the UK, a great university to attend is Lancaster University for a cyber security certificate.
Explanation:
A company has three (3) components in a system and requires all three to be operational for 24 hours, Monday to Friday. Failure of component 1 occurs as follows: Monday = No failure. Tuesday = 5 a.m. to 7 a.m. Wednesday = No failure. Thursday = 4 p.m. to 8 p.m. Friday = 8 a.m. to 11 a.m. Directions: Using the scenario above, respond to the items below. Calculate the MTBF (Mean Time Between Failures) and MTTR of component 1. Show your steps of how you calculated the MTBF. Steps: MTBF = Total Uptime / Number Failures Total Uptime = (Number of Days Required Operational x Hours per Day Available) - Number of Hours Not Available MTTR = Total Downtime / Number of Failures What does the MTBF measurement tell you about the goal of having 99.999% uptime or Information Availability on system components?
Answer:
Following are the code to this question:
#include<stdio.h>//defining header file
//using namespace std;
int main()//defining main method
{
float MTBF, MTTR, Total_up;//defining float variable
Total_up = (4 * 24) - 9;//defining Total_up variable that calculate Total uptime value
MTBF = Total_up / 3.0;//defining MTBF variable that calculate its value
MTTR = 9 / 3;//defining MTTR that calculate its value
printf("\n The total value of MTBF: %f",MTBF);//print value with message
printf(" \n The total value of MTTR: %f ",MTTR);//print value with message
return 0;
}
Output:
The total value of MTBF: 29.000000
The total value of MTTR: 3.000000
Explanation:
In the above-given code, three float variable "MTBF, MTTR, and Total_up" is defined, in the next step the "Total_up" variable is defined, that holds a value to calculate its value.
In the next step, the "MTBF, and MTTR" variable is defined, and in the "MTBF" variable, it uses Total_up variable value to calculate its value and use the print method to print the "MTBF and MTTR" value.
Write a Python3 program to check if 3 user entered points on the coordinate plane creates a triangle or not. Your program needs to repeat until the user decides to quit, and needs to deal with invalid inputs.
Answer:
tryagain = "Y"
while tryagain.upper() == "Y":
x1 = int(input("x1: "))
y1 = int(input("y1: "))
x2 = int(input("x2: "))
y2 = int(input("y2: "))
x3 = int(input("x3: "))
y3 = int(input("y3: "))
area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))
if area > 0:
print("Inputs form a triangle")
else:
print("Inputs do not form a triangle")
tryagain = input("Press Y/y to try again: ")
Explanation:
To do this we simply calculate the area of the triangle given that inputs are on plane coordinates i.e. (x,y).
If the area is greater than 0, then it's a triangle
If otherwise, then it's not a triangle.
This line initializes iterating variable tryagain to Y
tryagain = "Y"
while tryagain.upper() == "Y":
The following lines get the coordinates of the triangle
x1 = int(input("x1: "))
y1 = int(input("y1: "))
x2 = int(input("x2: "))
y2 = int(input("y2: "))
x3 = int(input("x3: "))
y3 = int(input("y3: "))
This calculates the area
area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))
This checks for the condition stated above.
if area > 0:
print("Inputs form a triangle") This is printed, if true
else:
print("Inputs do not form a triangle") This is printed, if otherwise
tryagain = input("Press Y/y to try again: ") This prompts the user to try again with another set of inputs

According to a survey of hikers on a trail, 50% of the hikers like Gatorade (G) and 40% like energy bars (E). 20% like both. Assume random selection:____________ a. Find the probability that a hiker likes Gatorade or energy bars b. If a hiker likes Gatorade, find the probability that he likes energy bars c. If a hiker likes energy bars, find the probability that he likes Gatorade.
Answer:
Explanation:
As per given data
Probability hikers like Gatorade (G) = P(G) = 50% = 0.5
Probability hikers like energy bars = P(E) = 40% = 0.4
Probability hikers like both = P(G and E) = 20% = 0.2
a)
To find the probability that a hiker likes Gatorade or energy bars use the following formula
P(G or E) = P(G) + P(E) - P(G and E )
P(G or E) = 0.5 + 0.4 - 0.2
P(G or E) = 0.7
b)
To find the probability that a hiker likes Gatorade or energy bars use the following formula
P(E|G) = P(E and G)/P(G)
P(E|G) = 0.2/0.5
P(E|G) = 0.4
c)
The probability that he likes Gatorade.
P(G|E) = P(G and E) / P(E)
P(G|E) = 0.2 / 0.4
P(G|E) = 0.5
(Python)Write an expression using Boolean operators that prints "Eligible" if user_age is greater than 17 and not equal to 25.
Sample output with input: 17
Ineligible
user_age = input("Input Age: ")
if int(user_age) <= 17:
print("Ineligible")
elif int(user_age) == 25:
print("Ineligible")
else:
print("Eligible")
:Here is some basic code. It takes an input, turns it into an int type value, and checks the parameters that you gave me. It errors out when you put in anything but a number.
Answer:
user_age = int(input())
if (user_age > 17) and (user_age != 25):
print('Eligible')
else:
print('Ineligible')
Explanation:
the code is very easy to do because it asks for it in Boolean operators. So user_age = int(input()) ## asks for user input
then it checks the status by seeing if the number is greater than 17 and not equal to 25. we know that > is greater and we know that != means not equal. Therefore, this will rule out both and then give the eligible or ineligible statement.
A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
printf("%0.2lf", yourValue);
Ex: If the input is:
5345
the output is:
2.67
Your program must define and call a function:
double StepsToMiles(int userSteps)
#include
/* Define your function here */
int main(void) {
/* Type your code here. */
return 0;
}
Answer:
The complete program is:
#include <stdio.h>
double StepsToMiles(int userSteps){
return userSteps/2000.00;
}
int main(void) {
int userSteps;
printf("User Steps: ");
scanf("%d",&userSteps);
printf("%0.2f", StepsToMiles(userSteps));
return 0;
}
Explanation:
This line defines the function
double StepsToMiles(int userSteps){
This returns the required output by dividing userSteps by 2000.
We used 2000.00 because we want it to return a floating point number
return userSteps/2000.00;
}
The main begins here
int main(void) {
This declares userSteps as integer
int userSteps;
This prompt user for input
printf("User Steps: ");
This gets user input
scanf("%d",&userSteps);
This calls the function and also returns the required output to 2 decimal places
printf("%0.2f", StepsToMiles(userSteps));
return 0;

Lola wants to install an add-in in Excel.She has to unblock the add-in to allow Excel to open the add-in file automatically.To do this,she right clicks on the add-in file and selects an option from the menu. What could the option be?
A) Copy
B) Delete
C) Rename
D) Properties
Answer:
The correct answer is:
Properties (D)
Explanation:
First of all, option D (Properties) is the option that makes the most sense in this scenario, because the other options: Copy, Delete, and Rename are unrelated commands to what is to be achieved.
Secondly and more practically, an add-in file may not load in excel, and most of the time it is blocked by default and has to be unblocked. The following steps are used:
1. close Excel if it is open
2. open the folder where the add-in file is located, right-click on the add-in file, and select "properties"
3. a display tray will appear, having the attributes: Read-only, Hidden, Advanced, and unblock. Click the checkbox against "unblock" and make sure it is checked.
4. click Apply and Click Ok
Voila, your add-in file is unblocked.
