Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 21 and a standard deviation of 5.
This means that
Find the Z score for a student that gets a 31
This is Z when X = 31. So
If she walks both ways then one way = 1/3 mile
Simplify √50.
Factor out 50.
√50 = √(5 x 5 x 2)
Note that there are 2 5's inside the parenthesis. Two of the same number when multiplied would become a whole number:
√(5 x 5) = 5
√50 = √(5 x 5 x 2) = 5√2
5√2 is your answer
