Hi There!
So basically you have to add, whenever you add with the same denominator you just add the numerator.
Steps
1. Add
+ 
2. Since they have the same denominators add the numerators, 1+4=5
3. You're total answer should be
, whenever you get the same number in the numerator and the denominator the answer will always be one.
Final Answer, + equals to one.
Hope This Helps :)

Answer:
Top 5% is 5.84 milliters and the bottom 5% is 5.60 millimeters.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Top 5%:
X when Z has a pvalue of 0.95. So X when Z = 1.645
Bottom 5%:
X when Z has a pvalue of 0.05. So X when Z = -1.645
Top 5% is 5.84 milliters and the bottom 5% is 5.60 millimeters.
To solve this we are going to use the kinematic equation for final velocity: 
where
is the final velocity
is the initial velocity
is the acceleration
is the time
We know for our problem that the the velocity at the beginning of the slope is
, so 
. We also know that the speed ad the bottom of the slope is 
, so 
. We also know that the acceleration is 
, so 
. Lets replace those values in our formula and solve for :
seconds
We can conclude that it takes the roller coaster 3 seconds to reach the bottom of the slope.
