Answer:
// 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:
c. Using the Data Refinery tool
Explanation:
Data wrangling and tidying in Data Science is the process whereby data to be analysed is obtained, cleaned and arranged before it is analysed in the environment.
Since Watson Studio happens to be an IBM premier integrated development environment for data science and artificial intelligence practitioners, there is need for them to have data softwares to make data scientists practitioners' works easier.
<em>In this scenario, the best tools to aid in tidying data in the Watson studio would be the use of </em><u><em>Data Refinery Tool.</em></u>
Answer:
import random
randomlist = []
for i in range(0,20):
n = random.randint(-29,30)
if n < 0 :
n = 100
randomlist.append(n)
print(randomlist)
Explanation:
The random module is first imported as it takes care of random. Number generation.
An empty list called randomliay is created to hold the generated random integers.
Using a for loop, we specify the range of random numbers we want.
Inside the for loop ; we attach our generated random integer which will be in the range (-29 to 30) in a variable n
For each n value generated, if the value is less than 0( it is negative, since all the values are integers), replace the value with 100.
What is the context of the question? With all that you have provided my best guess would be "computational function/solving"
