What is the quotient? URGENT!!
jeyben [28]

Answer:

The answer is A.

Step-by-step explanation:

You have to multiply by converting the second fraction into upside down :

\frac{4x + 1}{6x}  \div  \frac{x}{3x - 1}

=  \frac{4x + 1}{6x}  \times  \frac{3x  -  1}{x}

=  \frac{(4x + 1)(3x - 1)}{x(6x)}

=  \frac{12 {x}^{2}   -  4x + 3x - 1}{6 {x}^{2} }

=  \frac{12 {x}^{2} - x - 1 }{6 {x}^{2} }

Suppose the selling price of homes is skewed right with a mean of 350,000 and a standard deviation of 160000 If we record the se
lys-0071 [83]

Answer:

The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.

Step-by-step explanation:

The Central Limit Theorem estabilishes 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.

Population:

Suppose the selling price of homes is skewed right with a mean of 350,000 and a standard deviation of 160000

Sample of 40

Shape approximately normal

Mean 350000

Standard deviation s = \frac{160000}{\sqrt{40}} = 25298

The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.
