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)

For the most recent year available, the mean annual cost to attend a private university in the United States was $20,307. Assume
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

Ninety-five percent of all students at private universities pay less than what amount?

This is the 95th percentile, that is, X when Z has a pvalue of 0.95. So X when Z = 1.65.

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

1.65 = \frac{X - 20307}{4275}

X - 20307 = 1.65*4275

X = 27,361

So the answer is 27,361.

I will mark brainly, help me with this question please.​
Anna [14]

Step-by-step explanation:

Since x varies directly as \sqrt{y} we can write the relation as

x = k\sqrt{y}

where k is the constant of proportionality.

a) To solve for the k, we substitute the given values:

5 = k\sqrt{13} = k(13)

\Rightarrow k = \dfrac{5}{13}

b) The equation relation x and y can be written as

x = \dfrac{5}{13}\sqrt{y}

c) When y = 9,

x = \dfrac{5}{13}\sqrt{9} = \dfrac{5}{13}(3) = \dfrac{15}{13}
