Break the number within the radical symbol into 2 numbers: another number and a perfect square (when multiplied, they get the original number).
An example would be 48. The square root of 48 can be evaluated by breaking apart 48 into 16 (a perfect square) and 3 (another number). The square root of 16 is 4, so you take this number out of the radical symbol. Leave 3 within the symbol as it cannot be further reduced.
√48 = 4 √3.
Answer: C. How many mountain ranges are in the U.S.
Step-by-step explanation:
A statistical question first of all has to have a quantitative response i.e., answers should be in numbers.
The only two questions here that would yield a numeric answer are options C and D.
Furthermore, a statistical question has variability in it which means that the answer is based on multiple observations not just one. The observations in option C are mountain ranges and as the question requires finding out details about multiple mountain ranges, this is a statistical question.
This is opposed to option D which addresses issues surrounding just one mountain.
