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.

Why?</h2>
To solve the problem, we need to perform the operations and then, add like terms.
We need to apply the distributive property, which is defined by the following way:
Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:
We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.
So, we are given the expression:
Then, solving we have:
Hence, we have that the answer is:
Have a nice day!
X intercept: when y = 0
y intercept: when x = 0
Plug info inside the equation
3x + 7(0) = 42
3x = 42, x = 14
Therefore, x intercept: (14,0)
3(0) + 7y = 42
7y = 42, y = 6
Therefore, y intercept: (0,6)
Basically, you try to find 2 numbers that divide to 3/2. So, using trial and error, plug in numbers for x in this expression: x/24=3/2, and solve to find the number that makes it true. You end up getting 36/24=3/2. Hope that helps! :)
its 25 because yeah ......e.w.cds.vfc.fd.cdvfd dvfvfd
