Solnce55 [7]

Answer:

A. $(x^{2/7})(y^{-3/5})$

Step-by-step explanation:

The numerator is:

$\sqrt[7]{x^2} = (x^2)^{1/7} = x^{2/7}\\$

The denominator is:

$\sqrt[5]{y^3} = (y^3)^{1/5} = y^{3/5}$

The fraction is equivalent to:

$\frac{x^{2/7}}{y^{3/5}} =$
$(x^{2/7})(y^{-3/5})$

Correct choice is A

Answer:

0.024

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$
