38.38575 cm squared since if you multiply 97.5 * 0.3937, you get 38.38575
Based on the calculation below, the likelihood that if someone died they were a heavy smoker is 42.11%.
<h3>How do we calculate the likelihood of an occurrence?</h3>
Let:
Likelihood that a non-smoker will die = x
Therefore, we have:
Likelihood that a light smoker will die = 2 * x = 2x
Likelihood that a heavy smoker will die= 2 * 2x = 4x
From the above, we have:
Expected number of non smokers that will die = 50% * x = 0.5x
Expected number of light smokers that will die = 30% * 2x = 60%x = 0.6x
Expected number of heavy smokers that will die = 20% * 4x = 80%x = 0.8x
Total expected = 0.5x + 0.6x + 0.8x = 1.9x
Therefore, we have:
Likelihood that a heavy smoker died = Expected number of heavy smokers that will die / Total expected = 0.8x / 1.9x = 0.4211, or 42.11%

<span>Her travel time to her destination can be found by dividing 50km by 40km/h to get 1.25 hours or 1 hour 15 minutes. He travel time home can be found by dividing 50km by 60km/h to get 0.83 hours or. 50 minutes. The total time was 2.083 hours or 2 hours and 5 minutes. So here average speed is 100 divided by 2.083 hours = 48 miles per hour.</span>
