Answer:

Step-by-step explanation:

Dataset 1 (in increasing order)

{1, 4, x, 8}

Dataset 2 (in increasing order)

{2, 5, y, 9}

Median of dataset 1

[4 + x] / [2]

Median of dataset 2

[5 + y] / [2]

since the medians of the two given sets of data are the same,

=> [4 + x] / [2] = [5 + y] / [2]

=> 2(5 + y) = 2(4 + x)

=> 10 + 2y = 8 + 2x

=> 2y - 2x = 8 - 10

=> 2y - 2x = - 2

=> 2(y - x) = - 2

=> [2(y - x)] / [2] = [- 2] / [2]

denominators and numerators cancel out

=> (y - x) = - 1

Therefore, (y - x) ² = (-1)²

=> (y - x) ² = 1

Which of the following steps is included in the construction of a perpendicular line through a point on a line?
Molodets [167]

Answer:

Connect arcs that are above the original line with a straightedge ⇒ 2nd

Step-by-step explanation:

* <em>Lets revise how to construct a perpendicular line through a point</em>

<em>  on the line</em>

- <u>Given:</u> line AB and point P lies on it

1. Place your compass pin at P and draw an arc of any size below  

  AB that crosses the line twice at points C and D  

2. Stretch the compass to a larger distance

3. Place the compass pin on point C and draw a small arc above 

   the line  

4. Without changing the distance of the compass place the  

   compass pin on point D and draw another small arc intersects

   the small arc  from C at point E

5. <u>Using a straightedge, to join P which is on the original line and E </u>

    <u>which is the intersection point of the two small arcs above the </u>

    <u>original line,</u> then PE is perpendicular to AB  at E

- From the steps up the step is including in the construction of a

 perpendicular line through a point on a line is:

 <u><em>Connect arcs that are above the original line with a straightedge</em></u>

* <em>Remember:</em>

- The step of Connect arcs that are above and below the given line

  with a straightedge is in the construction a perpendicular from a

  point off the line

- The step of Create arcs on either side of a point that is off the

  given line is in the construction of a perpendicular bisector

  of a line

- The step of Create a copied angle by using the first two lines as the

  original angle in the construction of the parallel lines

- Look to the attached figure to help you

stellarik [79]

Answer:

4/6 or 66%

Step-by-step explanation:

Odd numbers from 1 to  6 are: 1, 3, 5

Numbers less than 4 are: 1, 2, 3

So there are  4/ 6 possible outcomes.

So the probability is 4/6 or 66%.
