3 1/2 x 1 1/2 x 2 = 2/2 ( in simplest form) not simplified is 7/2, as a decimal is 10.5, and as a mixed number is 10 1/2 hope it helps!

You are getting a line-up ready for a school kickball game. You have 7 girls and 7 boys. The rules state each child must kick th

Effectus [21]

Answer:

50,803,200 ways

Step-by-step explanation:

In this situation, since you should alternate girl-boy or boy-girl, the line-up can either start with a boy or a girl kicking which would yield one of the two following patterns:

BGBGBGBGBGBGBG or GBGBGBGBGBGBGB.

For each of those patterns, there are 7! ways to arrange all boys and 7! ways to arrange all girls. The number of ways that a line-up can be made for one round of kicking is:

$n=2*7!*7!\\n=2*(7*6*5*4*3*2)^2\\n=50,803,200\ ways$

There are 50,803,200 ways to set the line-up.

What is the value of 3^3 - (4^2 - 2^3)?

Illusion [34]

3³ - (4² - 2³)

3³ = 3x3x3 = 27

4² = 4x4 = 16

2³ = 2x2x2 = 8

3³ - (4² - 2³) = 27 - (16 - 8) = 27 - 16 + 8 = 19 (answer C)

I NEED SERIOUS HELP!!! <br> Find the volume of the rectangular prism <br> The volume is __cm. Cubed

GuDViN [60]

Answer: 88cm^2

Step-by-step explanation:

To find the answer of a rectangular prism, use this formula:

$A=2(wl+hl+hw)$

For your prism, h = 4, l = 6, and w = 2.

$A = 2(2*6+4*6+4*2)$

$A=2(12+24+8)$

Area is equal to 88 cm squared.

A health research institute collects information from 20 individuals on the number of years they have spent smoking cigarettes,

olga55 [171]

The correlation coefficient of the health research institute data measures the relationship between the age and the years of the smokers

The correlation coefficient is 0.53

<h3>How to calculate the correlation coefficient</h3>

The correlation coefficient (r) is calculated as:

$r = \frac{n(\sum xy) - \sum x \sum y}{\sqrt{[n \sum x^2 - (\sum x)^2][n\sum y^2 - (\sum y)^2}}$

Using the given parameters, we have:

$r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1257^2][20 * 836 - 116^2}}$

Evaluate the exponents

$r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1580049][20 * 836 - 13456}}$

Evaluate the products

$r = \frac{164980 - 145812}{\sqrt{[1976460 - 1580049][16720 - 13456}}$

Evaluate the differences

$r = \frac{19168}{\sqrt{[396411*3264}}$

Evaluate the product

$r = \frac{19168}{\sqrt{1293885504}}$

Evaluate the root

$r = \frac{19168}{35970.6}$

Evaluate the quotient

$r = 0.53$

Hence, the correlation coefficient is 0.53
