Answer:
84%
Step-by-step explanation:
The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.
Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:
68% + 16% = 84%.
Answer:
The population of bacteria can be expressed as a function of number of days.
Population = where n is the number of days since the beginning.
Step-by-step explanation:
Number of bacteria on the first day=
Number of bacteria on the second day =
Number of bacteria on the third day =
Number of bacteria on the fourth day =
As we can see , the number of bacteria on any given day is a function of the number of days n.
This expression can be expressed generally as where n is the number of days since the beginning.
