Answer:

B) Multiply each side by 3

Step-by-step explanation:

This is how to solve for h

$\frac{h}{3}$ + 7 = 5 (First Step --> Subtract 7 from both sides)

$\frac{h}{3}$ = - 2 (Second Step --> Multiply both sides by 3 to cancel out the denominator and to find just h)

h = -6

ANYONE?: Cassie is reading a book with 1,460 pages. She is on page 882. About what percent of the book does she have left to rea

andreyandreev [35.5K]

Answer:

around 40%

Step-by-step explanation:

This is a proportion question.

882 x

____ = ____

1,460 100

First, do 882 x 100 and get 88,200.

Then divide 88,200 by 1,460 to get around 60%.

Then 100-60= 40%.

Might be wrong but I'm pretty sure this is the answering method.

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.9 years with a

Bas_tet [7]

Answer:

5.9 years.

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 $s = \sqrt{\frac{p(1-p)}{n}}$

In this question:

Mean of the population is $\mu = 5.9$

If a sampling distribution is created using samples of the ages at which 69 children begin reading, what would be the mean of the sampling distribution of sample means?

By the Central Limit Theorem, the same population mean, of 5.9 years.
