Answer:

median = 11.5 . first quartile = 9.5 , third quartile = 14.5

Step-by-step explanation:

<h2><u>arrange the 12 numbers in order:</u></h2>

9,9,9,10,11,11,12,13,14,15,16,17

<h2><u>median </u></h2>

since there is an even number (12)

we can divide by 2

12 /2

= 6th position and 7th position

= 11 + 12

= 23 / 2 = 11.5

<h3>median is 11.5</h3>

<h2><u>first quartile</u></h2>

is also known as the lower quartile is half of the median position

6/2 = 3rd position and 7/2 = 3.5th position

9 + 10 = 19

19 / 2 = 9.5

<h3>first quartile is 9.5</h3>

<h2><u>third quartile </u></h2>

also known as upper quartile

is the position of median + position of lower quartile

= 6 +3 = 9th position and 7 +3 = 10th position

= 14 + 15 = 29

29/2 = 14.5

<h3>third quartile is 14.5</h3>

<u>Answer-</u>

<em>The height of the prism is</em><em> 6 units</em>

<u>Solution-</u>

As the base of the prism is a hexagon consisting of 2 congruent isosceles trapezoids.

So,

$V_{Prism}=Area_{Base}\times Height$

And,

$Area_{Base}=2\times \text{Area of the trapezoid}$

Also,

$\text{Area of the trapezoid}=\dfrac{1}{2}\times \text{Height}\times (\text{Sum of two parallel lines})$

$=\dfrac{1}{2}\times 3\times (5+8)\\\\=\dfrac{39}{2}$

Putting all the values,

$V_{Prism}=2\times \dfrac{39}{2}\times Height=39\times Height$

As the volume is given, so

$\Rightarrow 39\times Height=234$

$\Rightarrow Height=\dfrac{234}{39}=6$

Answer: -1/9

Step by step explanation:

The common difference of an arithmetic sequence can be found by picking 2 consecutive terms, and subtracting the second from the first. For example, if I chose the terms 2 and 1 8/9, I would find the common difference by:

1 8/9 - 2, which is equal to -1/9.

You can confirm this by picking another pair of consecutive terms. Let's pick 1 7/9 and 1 2/3:

1 2/3 - 1 7/9 = -1/9, as 1 2/3 = 1 6/9, so 1 6/9 - 1 7/9 = -1/9
