Hello!
1 floz divided by 100 = 0.01
0.01 x 10 = 0.1 floz for 10 drops.
Answer:
Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard table or excel and we got:
54 rounded to the nearest 10 would be 50 because 54 is closer to 50 than 60.
So, the answer is 50.
Hope it helps
It takes 3 minutes to fill 60L, so it takes 1 hour to fill 1200L.
The equation would be 6x+5y=316. X represents the car travelers and the y represents the bus travelers
