Answer: 22 1/2
Step-by-step explanation: The scientist starts off his experiment with only <u>100</u> bacteria cells okay. It takes <u>15</u> hours for the bacteria cells to double there population. Meaning <u>15 hours</u>=<u>200</u> bacteria cells. So what you have to do know is find out what to do next which is count <u>15</u> in <u>half.</u> After that step you should get <u>7 1/2.</u> know what you do is add <u>15+7 1/2= 22 1/2.</u> meaning <u>22 1/2</u> is your answer.
It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2
The number of customers I would have expected to win the prize is 6.
<h3>How many more customers would I have expected to win the prize?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Based on the probability, the number of customers I would have expected to win: 0.18 x 300 = 36
How many more people I would have expected to win : 36 - 30 = 6
