Step-by-step explanation:

Given

$\sqrt[3]{-27n^{27} }$

= $\sqrt[3]{-27}$ × $\sqrt[3]{n^{27} }$

= - 3 × $n^{9}$

= - 3 $n^{9}$

Alecia walked 3/10 of a mile from school,stopped at the grocery store on the way, then walked another 4/10 of a mile home.Georgi

Nutka1998 [239]

Answer:

Alecia lives farther from school

Step-by-step explanation:

<em>Georgia</em>

we know that

The distance from the school to her home is 67/100 of a mile

$\frac{67}{100}=0.67\ miles$

<em>Alecia</em>

we know that

The distance from the school to her home is

3/10 of a mile plus 4/10 of a mile

$\frac{3}{10}+\frac{4}{10}=\frac{7}{10}=0.7\ miles$

Compare the distances

$0.7\ miles>0.67\ miles$

therefore

Alecia lives farther from school

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there

Jobisdone [24]

Answer:

60,949,324,800

Step-by-step explanation:

We solve the above question using Permutation formula

The formula for Permutation =

nPr = n!/(n - r)!

Total Amount in a Set (n) = 20 persons

Amount in each Sub-Set (r) = 9 batting order

Hence:

20P9 = 20!/(20 - 9)!

= 60,949,324,800

Therefore, the different batting orders they would have are: 60,949,324,800

sleet_krkn [62]

Answer:

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Step-by-step explanation:

Central Limit Theorem

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

3% of books borrowed from a library in a year are downloaded.

This means that $p = 0.03$

SRS of 75 books.

This means that $n = 75$

What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books

By the Central Limit Theorem

Mean: $\mu = p = 0.03$

Standard deviation: $s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.03*0.97}{75}} = 0.0197$

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
