</h2>
Step-by-step explanation:
<h3>

</h3>
To solve for k first multiply both sides by 3
That's
<h3>

</h3>
Next divide both sides by f in order to isolate k
We have
<h3>

</h3>
Simplify
We have the final answer as

25% is equal to 1/4, so if 300 is 1/4 and we need to find the total, then we should divide 300 by 4.
300 • 4 = 1200, thus 25% of 1200 is 300!
Hope this helps.
Answer:
The 99th percentile for a man’s arm span is 80.47 inches.
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:

99th percentile
X when Z has a pvalue of 0.99. So X when Z = 2.327.




The 99th percentile for a man’s arm span is 80.47 inches.
