Java output caffeine levels FAQA half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours inhumans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours.Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("After 6 hours: %.2f mg\n", yourValue);Ex: If the input is:100the output is:After 6 hours: 50.00 mgAfter 12 hours: 25.00 mgAfter 24 hours: 6.25 mgNote: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg.407614 2611836.q«Begy7|0/10LABACTIVITY2.19.1: LAB: Caffeine levelsLoad default template...LabProgram.java75°F1 import java.util.Scanner;23 public class LabProgram {4Type here to searchpublic static void main(String[] args)Et$0C LabProgram.javaLoad default1 import java.util.Scanner;S23 public class LabProgram {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);double caffeineMg; // "double" supports floating-point Like 75.5, versus int for integers like 75.caffeineMg = scnr.nextDouble();/* Type your code here. */Submit modeRun your program as often as you'd like, before submitting for grading.

4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }
The short-term, 0-24 hours, parking fee, F, at an international airport is given by the following formula: Where int(h + 1) is the integer value of h + 1. For example, int(3.2) = 3, int(4.8) = 4. Write a program that prompts the user to enter the number of hours a car is parked at the airport and outputs the parking fee.
(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
Calories = ( (Age x 0.2757) + (Weight x 0.03295) + (Heart Rate x 1.0781) — 75.4991 ) x Time / 8.368 Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output the average calories burned for a person. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("%.2f", yourValue); Ex: If the input is: 49 155 148 60 the output is: Calories: 736.21 calories

A long-distance carrier charges the following rates for telephone calls: Starting Time of Call Rate per minute ($) (**only depends on Starting Time) 00:00 – 06:59 0.10 07:00 – 19:00 0.45 19:01 – 23:59 0.30 Write a program that asks for the starting time and the number of minutes of the call, and displays the charges. The program should ask for the time to be entered as a floating-point number in the form HH.MM. For example, 07:00 hours will be entered as 07.00, and 16:28 hours will be entered as 16.28. Input Validation: The program should not accept times that are greater than 23:59. Also, no number whose last two digits are greater than 59 should be accepted. Assuming num is a floating-point variable, the following expression will give you its fractional part: num – static_cast<int>(num);

Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared. Calculate a persons Body Mass index using their weight in pounds. This means you must first convert pounds to kilograms (kg) then apply the formula above. In converting pounds to kg, 1 pound = 0.453592 kg. So to convert pounds to kg, either multiply the pound value by 0.45359237 or divide by 2.2046226218. Then you must convert their height in inches to meters. The length in meters is equal to the inches multiplied by 0.0254. Write a program that accepts a users height as an integer in inches and their weight in pounds. Convert those inputs to their metric equivalents outlined above and determine their body mass index. Display what the conversions from and to their metric equivalents are. Display the body mass index and the category it belongs to.

Suppose you have a certain amount of money in a savings account that earns compound monthly interest, and you want to calculate the amount that you will have after a specific number of months. The formula, which is known as the future value formula, is:F=P×(1+i)tThe terms in the formula are as follows:o F is the future value of the account after the specified time period.o P is the present value of the account.o i is the monthly interest rate.o t is the number of months.Write a program that prompts the user to enter the account’s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function named futureValue that returns the future value of the account, after the specified number of months. The program should display the account’s future value. i attached the screenshot of the output so the output should look like that.
