frozen [14]

Answer:

20 x 30 = 600

3,600/600=6

Check if it works

20 x 30 = 600

600 x 6 = 3,600

the missing width is 6

Eight committee members are meeting in a room that has twelve chairs. In how many ways can they sit in the chairs

amm1812

Answer:

<h2>495 different ways</h2>

Step-by-step explanation:

We will use the combination rule to solve this questions since it bothers selection. Combination has to do with selection.

If r objects are to be selected from n pool of objects, this can be done in nCr number of ways.

nCr = n!/(n-r)!r!

If there are Eight committee members meeting in a room that has twelve chairs, the number of ways they can sit in the chair can be done in 12C8 number of ways.

12C8 = 12!/(12-8)!8!

12C8 = 12!/4!8!

12C8 = 12*11*10*9*8!/4*3*2*8!

12C8 = 12*11*10*9/4*3*2

12C8 = 11*10*9/2

12C8 = 11*5*9

12C8 = 495

<em>Hence the committee can sit in the chairs in 495 different ways</em>

What is the mean and mad of this data set?

larisa86 [58]

Answer:

The mean number of gerbils seen per day is 6.

The mean absolute deviation of the data is 2.29.

Step-by-step explanation:

The mean of a data set is the value that represents the entire data set. It is the average value.

The formula to compute the mean of a data set is:

$\bar x=\frac{1}{n}\sum X$

The mean absolute deviation (MAD) of a data set is the average distance amid each value and the mean. The MAD provides us with an idea about the deviation in the data set.

The formula to calculate the value of MAD is:

$MAD=\frac{1}{n}\sum |x-\bar x|$

The data set for the number of gerbils seen per day is:

S = {2, 3, 5, 7, 8, 8, 9}

Compute the mean of the data as follows:

$\bar x=\frac{1}{n}\sum X$

$=\frac{1}{7}\times [2+3+5+7+8+8+9]\\\\=\frac{1}{7}\times 42\\\\=6$

The mean number of gerbils seen per day is 6.

Compute the mean absolute deviation of the data as follows:

$MAD=\frac{1}{n}\sum |x-\bar x|$

$=\frac{1}{7}\times [|2-6|+|3-6|+|5-6|+|7-6|+|8-6|+|8-6|+|9-6|]\\\\=\frac{1}{7}\times 16\\\\=2.2857\\\\\approx 2.29$

Thus, the mean absolute deviation of the data is 2.29.
