$12.95 for 3 pounds of nuts or $21.45 for 5 pounds of nuts

Mathematics

First, find the base rate of both of the numerals, to do this simply divide the price by the number of units.

12.95 divided by 3 is 4.32 ( rounded to nearest cent )

21.45 divided by 5 is 4.29 ( rounded to nearest cent )

So, if you want the better deal ( which is what I've interpreted ), then 5 pounds of nuts is the better deal <u>BY</u> 3 cents.

Hope this helps, if not, comment below please!!!!

Four thousand divided by 10 equal hundred divided ten

Alexeev081 [22]

I am quite confused what this problem asks about.

We are given that:

4,000 / 10 is equal to hundred / 10

I believe this problem is asking us how much in hundreds is 4,000

Therefore the answer is: 40

Such that:

<span>4,000 / 10 = 40 hundreds / 10</span>

There is a theory that children wearing superhero costumes are more likely to harm themselves because of the unrealistic impress

____ [38]

Answer:

$Mean = 47$

$n = 6$

$s= 16.56$

$\sqrt n = 2.45$

$SEM = 11.55$

Step-by-step explanation:

Given: The above data

Solving (a): Mean of each group

Mean is calculated as:

$Mean = \frac{\sum x}{N}$

$Mean = \frac{55 + 31 + 58 + 20 + 47 + 37+68 + 32 + 85 + 69 +58 + 52+26 + 47 + 30 +35 + 53 + 43}{18}$

$Mean = \frac{846}{18}$

$Mean = 47$

Solving (b): The sample size of each group

This is the number of rows in each group.

Hence:

$n = 6$

Solving (c): Standard deviation (s)

This is calculated as:

$s = \sqrt{\frac{\sum (x - \bar x)^2}{N}}$

So, we have:

$s= \sqrt{\frac{(55 - 47)^2 + (31 - 47)^2 +......... + (43 - 47)^2}{18}}$

$s= \sqrt{\frac{4936}{18}}$

$s= \sqrt{274.22}$

$s= 16.56$

Solving (d): Square root of n

$\sqrt n = \sqrt 6$

$\sqrt n = 2.45$

Solving (e): SEM

This is calculated as:

$SEM = \frac{s}{\sqrt N}$

$SEM = \frac{47}{\sqrt{16.56}}$

$SEM = \frac{47}{4.07}$

$SEM = 11.55$
