X - 3 + 2x = 90
3x - 3 = 90
3x = 90 + 3
3x = 93
x = 93/3
x = 31
< KPN = 2x......2(31) = 62
< MPL = x - 3....31 - 3 = 28
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.
