I think that the answer is A, because in the range, none of the numbers should be the same, and the numbers are all different in choice A
For this question, 0.008 is the answer.
You can assume x is that number
X multiply 10 = 0.08
To get rid of 10, divide 10 by two sides
As a result, x = 0.008
X-5+5x-12=25
x+5x=25+5+12
6x=42
x=42/6
x=7
Range: maximum - minimum
IQR: third quartile - first quartile
median: middle number once all numbers are put in numerical order
