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 400 and a standard deviation of 60.
This means that 
z=3
We have to find X when Z = 3. So

can you explain make it more clear what the question is
Step-by-step explanation:
Answer:How are the areas of the smaller squares related to the area of the biggest square Do you notice something? The Pythagorean theorem says that the areas of the two smaller squares add up to be the same as the area of the largest square
