A survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have.
wolverine [178]

Answer:

<u>The closest statement is B. The median for the students is 2 and the median for the teachers is 3.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students = 20

Siblings   0   1   2   3   4   5   6   7   8   9

Students  2  4  7   5   2   0   0   0   0  0

Number of teachers = 20

Siblings  0   1   2   3   4   5   6   7   8   9

Teachers  1  3  2   4    5   3   1   0   1   0

2. Which statement compares the medians of the data?

Let's recall that the median of a set of data (students or teachers) is the middlemost number in the set. The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers, the 10th and 11th values from left to right for the students and teachers.

Upon saying that, let's meet the median of the data sets provided:

Median for the students = 10th and 11th values/2

<u>Median for the students = (2 + 2)/2 = 2</u>

Median for the teachers = 10th and 11th values/2

<u>Median for the teachers = (3 +4)/2 = 3.5</u>

<u>The closest statement is B. The median for the students is 2 and the median for the teachers is 3.</u>

A rectangular prism has a base that is 4 m by 6 m and a height of 10 m. If all dimensions are doubled, what happens to the volum
nirvana33 [79]
When the dimensions of a rectangular prism will be doubled, its volume won't only be doubled but it will be 8 times as much.

The original volume of the rectangular prism is LxWxH.

V= LxWxH
V= (6m) (4m) (10m)
V= 240m³

If we double the dimensions, the volume would be

V= 2L x 2W x 2H
V= 2 x 6m x 2 x 4m x 2 x 10m
V= 2 x 2 x 2 x 6m x 4m x 10m
V= 2³ (6m x 4m x 10m)
V= 2³ x 240m³
V = 8 x 240m³
V= 1920 m³

The new volume now is 1,920 m³, which makes the rectangular prism larger than the original.

goldfiish [28.3K]

Answer:

Step-by-step explanation:

\frac{a-b}{\sqrt{a} -\sqrt{b}} =\sqrt{a} +\sqrt{b}\\or ~a-b=(\sqrt{a} +\sqrt{b})(\sqrt{a}  -\sqrt{b} )=(\sqrt{a} )^2-(\sqrt{b} )^2 =a-b

There are 11 women and 9 men in a certain club. If the club is to select a committee of 2 women and 2 men, how many different su
Lelechka [254]

Answer:

1980

We can choose 2 men from 9 in 36 in ways.

We can choose 2 women from 11 in 55 ways.

For any arrangement of 2 men there are 55 ways of combining them with 2 women => 55 * 36 = 1980 total ways.

If you're wondering how i got the numbers i used the combination formula:

C(n, k) = \frac{n!}{k!(n-k)!}
