The following equations estimate the calories burned when exercising (source): Women: Calories = ( (Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022 ) x Time / 4.184 Men: Calories = ( (Age x 0.2017) + (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969 ) x Time / 4.184 Write a program with inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for women and men. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 49 155 148 60 the output is: Women: 580.94 calories Men: 891.47 calories

In the game of 10-pin bowling the bowler has two attempts to knock down pins for every frame of 10-pins, and scores a point for each pin knocked down. If all the pins are knocked down with two attempts, the bowler gets a bonus - whatever score they obtain with their next bowl is doubled. If all the pins are knocked down on the 1st attempt, no 2nd attempt is allowed, and the bowler gets a bonus – whatever score they obtain on their next two bowls are doubled. A student attempts to capture this scoring system in VHDL code, a fragment of which is shown in Figure Q4. Q4 (a) Draw the state transition diagram described by the VHDL of Figure Q4. Discuss whether the VHDL of Figure Q4 correctly scores a game of 10-pin bowling.
