Can someone show the steps to factor 15x^x y^2 – 3x^3 y+75x^4

umka21 [38]

Step 1- Find the Greatest common factor (GCF)
GCF = 3
Step 2- Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(15x^xy^2/3 + -3x^3y/3 + 75x^4/3)
Step 3- Simplify each term in the parentheses
3(5x^xy^2 - x^3y + 25x^4)

Maksim231197 [3]

Answer:

27,361.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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:

$\mu = 20307, \sigma = 4275$
