Answer:
Dispersion
Step-by-step explanation:
Given a set of scores {a1, a2, ..., an} ordered in value, the range can be described as the difference between the highest and the lowest value. We can write it as:
range = an - a1
Thus, the range provides information about the dispersion of our set of values. A high range means that the highest and the lowest value are highly separated, on the other hand, a low range mean that there is a little difference between those values.
This is usually used to measure dispersion on a set of values, together with standard deviation and interquantile range. However, we cannot maintain that one is better than the others.
The answer is 30°.
Rule: All three sides must add up to 180°.
Since A=60 and the side vertical to the angle which is 90° then side C would be C=90° and that adds up to 150°, so you can conclude that angle B is 30°.

X, y - the numbers
The sum of the two numbers is 50.

The first number is 43 less than twice the second number.

The numbers are 19 and 31.
