Answer:

The first quartile, denoted by Q1 , is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1 . The third quartile, denoted by Q3 , is the median of the upper half of the data set.

-2x+2&gt;3x-8<br><br> 50 points
Blababa [14]

Given:

The inequality is

-2x+2>3x-8

To find:

The solution of the given inequality.

Solution:

We have,

-2x+2>3x-8

Isolate the variables terms on the left side.

-2x-3x>-2-8

-5x>-10

Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.

\dfrac{-5x}{-5}

x

Therefore, the correct option is D.

Answer:

<em>Probability ≈ 0.3571</em>

Step-by-step explanation:

Consider the steps below;

Total Number of Outcomes - 9C4,\\9 ! / 4 ! * ( 9 - 4 ),\\9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 126,\\\\Number of Outcomes - 3C2 * ( 6C2 ),\\3C2 = 3,\\6C2 = 15,\\\\Number of Outcomes = 3 * 15 = 45,\\\\Probability; 45 / 126 = ( About ) 0.3571

<em>Solution; Probability ≈ 0.3571</em>

Plz help ill give you brainlist
GaryK [48]
In terms of diameter (d), the area (A) of a circle is given by
  A = (π/4)d²
For your larger circle ...
  A = (π/4)*(24 km)²
  A = 144π km² . . . . . . . . area of larger circle

For your smaller circle ...
  A = (π/4)*(8 km)²
  A = 16π km² . . . . . . . . . area of smaller circle


The ratio of the two areas is
  (larger area)/(smaller area) = ((π/4)*(24 km)²) / ((π/4)*(8 km)²)
  = (24/8)² . . . . . . . . . . . . π/4, km cancel, so it simplifies to this
  = 3²
  = 9 . . . . . . this many small circles have the same area as the larger circle

Changing km to ft does not change the ratio of areas.
