Answer:

  • lowest value is: 6
  • highest value is: 25.
  • Median (Q_{2}) is 16.
  • lower quartile (Q_{1}) is: 10.
  • third quartile (Q_{3}) is: 20.

Step-by-step explanation:

We are given a set of the data as:

9 22 16 12 16    10 22 16 17 8    20 18 10 20 25  6 14 10 14    20

on arranging this data in ascending order we have:

6    8     9    10    10    10    12    14   14    16    16    16    17     18      20    20    20   22   22    25

Hence, the lowest value is: 6

The highest value is: 25.

Now the data is divided into 3 quartiles.

Median (Q_{2}) is defined as the central tendency of a data i.e. the middle value of the data.

Hence the median here will lie between: 16 and 16.

Hence the median (Q_{2}) is 16.

Now the lower set of data is:

6    8     9    10    10   10    12    14   14  

Hence, the lower quartile(Q_1) is the median of the lower set of data i.e. the middle term in the following lower set of data.

Hence, the lower quartile (Q_{1}) is: 10

Similarly the upper set of data is given as:

16    17     18      20    20    20   22   22    25

Hence, the third quartile (Q_3) is the median of the lower set of data i.e. the middle term in the following lower set of data.

Hence, the third quartile (Q_{3}) is: 20

△ABC is a right isosceles triangle, the centers of two arcs are the midpoint of AB
mel-nik [20]

Answer:

  0

Step-by-step explanation:

Let's define 3 areas:

  • S = area of semicircle with radius 6 in (diameter AB)
  • T = area of quarter circle with radius 6√2 in (radius AC)
  • U = area of triangle ABC (side lengths 6√2)

The white space between the "moon" and the triangle has area ...

  white = T - U

Then the area of the "moon" shape is ...

  moon = S -white = S -(T -U) = S -T +U

The area we're asked to find is ...

  moon - triangle = (S -T +U) -U = S -T

__

The formula for the area of a circle of radius r is ...

  A = πr²

So, ...

  S = (1/2)π(6 in)² = 18π in²

and

  T = (1/4)π(6√2 in)² = 18π in²

The difference in areas is S -T = (18π in²) -(18π in²) = 0.

There is no difference between the areas of the "moon" and the triangle.

What is the range of the data? 2,8,7,8,6,15,6,3,8
creativ13 [48]

Answer:

13

Step-by-step explanation:

The range of a data set is the difference between the greatest and least values in the set. In this case, the greatest value is 15 and the least value is 2 so the range is 15 - 2 = 13.
