Normal Probability Distribution:
Problems of normal distributions 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.
Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in.
This means that
Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team.
This is the 100 - 2.5 = 97.5th percentile, which is X when Z has a pvalue of 0.975, so X when Z = 1.96.

C = 75 in
Answer:
C)
Step-by-step explanation:
We are given that
We have to find the additional fact which proves that triangle RST and triangle WXY are congruent.
In triangle RST
(Triangle angles sum property)
Substitute the values then we get
When two triangles are congruent then each part of one triangle is congruent to its corresponding parts of another triangle.
Therefore, if
Then,
Therefore,
Hence, option C is correct.
