Find the 5 number summary for the data shown x 3.1 10.2 12 12.1 12.2 15.3 27.9 30
Kazeer [188]

Answer:

  Min.     1st Qu.    Median      Mean       3rd Qu.        Max.  

  3.10     11.55       12.15        15.35        18.45         30.00

Step-by-step explanation:

The five-number summary includes five things that are:

1. Minimum Value

2. First Quartile (Q₁)

3. Median

4. Third Quartile (Q₃)

5. Maximum Value

So,  

1. Minimum Value = 3.10

It can be found by arranging the data in ascending order, the first value we will get is the minimum value.

2. First Quartile is the middle value between Minimum value and Median of data after arranging data in ascending order.

First Quartile (Q₁) = 11.55

3. Median is the middle value of the data after arranging them in ascending order.  

Median = 12.15

4. The third Quartile is the middle value between Median and Maximum Value of data after arranging data in ascending order.

Third Quartile (Q₃) = 18.45

5. Maximum Value is the largest value of the data or is the last value after arranging the data in ascending order.

Maximum Value = 30.

Percentiles are mostly use in very large data. Here n percent of data shows the nth percentile.

A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm,
Svetradugi [14.3K]

Answer:

The quadratic equation that best models the volume of the box (in terms of W) is:

70W-5W^2

Step-by-step explanation:

The perimeter of the rectangular base = 28cm

Perimeter of a rectangle = 2(L+W)

2(L+W)=28

L+W=14

L=14-W

Volume of the Box= LWH

Since L=14-W and Height Of the Box= 5cm

Volume of the Box= (14-W)W X 5

=5(14W-W^2)\\                             =70W-5W^2
