Answer: B. 95.0
Step-by-step explanation:
In statistics , the famous empirical rule says that " if the data is normally distributed then 68% of the observations will be contained within standard deviations from the arithmetic mean, 95% of the observations will be contained within
standard deviations from the arithmetic mean and 99.7% of the observations will be contained within
standard deviations from the arithmetic mean".
Hence, B is the correct answer.
You take the three zeros and put them back with the x s
(x-6)(x+5)(x-2) they are reversed when you put them back in
multiply the first two and get
simplify to
Multiply it out again and get
finally simplify and get
So the answer is the first one
