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 $400 and standard deviation $20.
This means that
How much should be budgeted for weekly repairs and maintenance to provide that the probability the budgeted amount will be exceeded in a given week is only 0.1?
This is the 100 - 10 = 90th percentile, which is X when Z has a p-value of 0.9, so X when Z = 1.28.
$425.6 should be budgeted for weekly repairs and maintenance.
Explanation:
Prime factorization says that, if a number is prime then the only way it can be factored is, 1 times the number itself.
But if the number is composite, it can be expressed as a product of prime factors. This method is called prime factorization.
For example: 12 is a composite number, it can be written in the form of prime factorization as,
Here we can see that 12 is expressed as the product of primes only. This is called prime factorization.
