Answer:
z * sigma+u = x
Step-by-step explanation:
z = (x-u)/ sigma
z is the z score, u is the mean, sigma is the standard deviation
We need to solve for x
Multiply each side by sigma
z * sigma = (x-u)/ sigma * sigma
z * sigma = x-u
Add u to each side
z * sigma+u = x-u+u
z * sigma+u = x
Answer:
there was a 16% increase since 2010 to 2012
Step-by-step explanation:
lets say the train had 100 people on it in 2010 and in 2011 it had an 8% increase which then brings you to 8 plus 100 and you get 108.
Now in 2012 there was an increase 8%, so you will add 8 to your previous answer 108 and receive 116. So now there was 16 more passengers in 2012 than in 2010. Transfer the 16 passengers into 16% and you now have your answer.
