Answer:
Ari catches up to Amanda at 19.3 meters
Step-by-step explanation:
Given :
Ari is swimming a 25-meter race.
After swimming 6 meters she catches up to Amanda in a ratio of 7:3 from the 6-meter mark.
Solution :
The distance between 6 meters and 25 meters = 19 meters.
Since she catched Amanda in ratio 7:3
So, she catched her at 7/10 of the distance
So, the distance at which she catched Amanda =
=13.3
Ari catches 13.3 metres from 6 m marks
The point on number line at which she catches her = 13.3+6
Hence Ari catches up to Amanda at 19.3 meters

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".
Solutio to the problem
Let X the random variable that represent the amount of beer in each can of a population, and for this case we know the distribution for X is given by:
Where and
For this case we select 6 cans and we are interested in the probability that the total would be less or equal than 72 ounces. So we need to find a distribution for the total.
The definition of sample mean is given by:
If we solve for the total T we got:
For this case then the expected value and variance are given by:
And the deviation is just:
So then the distribution for the total would be also normal and given by:
And we want this probability:
And we can use the z score formula given by:
