Can you please post a picture of the chart, and questions that have to do with the chart? Then maybe I could solve it.
Answer:
95%
Step-by-step explanation:
The empirical rule states that if data follows normal distribution then the percentage of observations falls within one, two and three standard deviation around the mean are
i) 68% falls within one standard deviation
ii) 95% falls within two standard deviation
iii) 99.7% falls within three standard deviation.
Hence 95% of the observations will fall within two standard deviations around the mean if the data follows normal distribution.
Step-by-step explanation:
By using mid point theorem we get,
VT=2BC
x+6=2(x+5)
x+6=2x+10
6-10=2x-x
-4=x
x= -4
Parallel lines will always be the same distance apart.
