The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article (source): 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: print('calories: {:. 2f} calories'. Format(calories)).
