// here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare variable
double caffeine;
// scanner object to read input from user
Scanner scr=new Scanner(System.in);
System.out.print("Enter the initial amount of caffeine:");
// read the initial amount of caffeine
caffeine=scr.nextDouble();
// calculate amount of caffeine after 6,12,18 hours
for(int i=1;i<=3;i++)
{
System.out.println("After "+ i*6+" hours:"+(caffeine/2)+" mg");
// update the caffeine after every 6 hours
caffeine=caffeine/2;
}
}catch(Exception ex){
return;}
}
}
Explanation:
Create a variable "caffeine" to store the initial amount of caffeine given by user. Run a loop for three time, it will calculate the amount of caffeine left after every 6 hours.First it will give the amount of caffeine left after 6 hours, then caffeine left after 12 hours and in last caffeine after 18 hours.
Output:
Enter the initial amount of caffeine:100
After6 hours:50.0 mg
After12 hours:25.0 mg
After18 hours:12.5 mg

Answer:
=IF(D3>50; E3; F3) and =IF(A1>60;"Pass";"Fail") are valid IF formulas.
Explanation:
P.S - The exact question is -
To find - Select the correct answer from each drop-down menu. Which IF formulas are valid? _____ and _____ are valid IF formulas.
FIRST BLANK
=IF(D3>50; E3; F3)
=IF(D3>50);( E3; F3)
=IF(10<5;23);("Incorrect")
SECOND BLANK
=IF(A1>60;"Pass";"Fail")
=IF(A1>60); ("Pass"; "Fail")
=IF(A1>60; ("Pass"; "Fail"))
Solution -
An IF structure is built following this pattern:
IF(TEST;IF TRUE;IF FALSE)
So,
The correct option is -
=IF(D3>50; E3; F3) and =IF(A1>60;"Pass";"Fail") are valid IF formulas.
