Answer:
0.7
Step-by-step explanation:
An outlier of the data set is the data point which is quiet different from the rest of the data points or we can say that they lie outside the the other points.
Since in the given data, the similar data points ranges from 3.1 to 5.8, all points are nearly in between in this range but 0.7 is the only point which does not lie in this range. Hence, 0.7 is the outlier of the given data set.
One can also find the outlier by arranging the given data set from lowest to greatest that is if we arrange 3.1, 5.3, 4.3, 0.7, 5.6, 5.2, 5.8, 5.4 from least value to the greatest value that is 0.7, 3.1, 4.3, 5.2, 5.3, 5.4, 5.6, 5.8, we see that there is a large change in the value of the median from 0.7 to 3.1 as compared to rest of the values.
Median of 0.7 and 3.1 is =
, while median of rest of the data points are nearly same.
Thus, the outlier will be 0.7.

Suppose you add x liters of pure water to the 10 L of 25% acid solution. The new solution's volume is x + 10 L. Each L of pure water contributes no acid, while the starting solution contains 2.5 L of acid. So in the new solution, you end up with a concentration of (2.5 L)/(x + 10 L), and you want this concentration to be 10%. So we have
and so you would need to add 15 L of pure water to get the desired concentration of acid.
