aleksley [76]

Answer:

Following are the code to this question:

code:

=IF(EXACT(I2,"Yes"),"Elected",IF(EXACT(K2,"Yes"),"Yes","No"))

Explanation:

In the given the data is not defined so we explain only the above code, but before that, we briefly define working of if the function that can be defined as follows:

The If() function, is used only when one of the logical functions and its value must return the value true. or we can say it only return a true value.
In the above function, a column "Elected" is used that uses other column values to check this column value is equal if this condition is true it will return "yes" value.

Exercise 3.6.9: 24 vs. "24"5 points

Anton [14]

This is all you need to do for this one add quotes around the number to make it a string. Then for the question I don't know if you need to answer it but I said that when there is only one string it creates and addition problem of 24 + 24 and then when there are two strings it puts them right next to each other making it look like the number 2424.

Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example

jasenka [17]

Answer:

public class Main

{

public static void main(String[] args) {

int userNum = 40;

while(userNum > 1){

userNum /= 2;

System.out.print(userNum + " ");

}

Explanation:

*The code is in Java.

Initialize the userNum

Create a while loop that iterates while userNum is greater than 1. Inside the loop, divide the userNum by 2 and set it as userNum (same as typing userNum = userNum / 2;). Print the userNum

Basically, this loop will iterate until userNum becomes 1. It will keep dividing the userNum by 2 and print this value.

For the values that are smaller than 1 or even for 1, the program outputs nothing (Since the value is not greater than 1, the loop will not be executed).

3.14 LAB: Simple statistics for Python

Ad libitum [116K]

Answer:

Following are the correct python code to this question:

n1 = float(input('Input first number: '))#input first number

n2 = float(input('Input second number: '))#input second number

n3 = float(input('Input third number: '))#input third number

n4 = float(input('Input fourth number: '))#input fourth number

average = (n1+n2+n3+n4)/4 #calculate input number average

product = n1*n2*n3*n4 # calculate input number product

print('product: {:.0f} average: {:.0f}'.format(round(product),round(average))) #print product and average using round function

print('product: {:.3f} average: {:.3f}'.format(product,average)) #print product and average value

Output:

Please find the attachment.

Explanation:

The description of the above python code can be defined as follows:

In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
In the last line, the print method is used, which prints its variable value by using a round and format method.
