since 14 is 2/3's of 21 the equation would be y=2/3x

V=(1/3)hpir^2
d/2=r
2.75/2=1.375
to make volume 4 times more
multiply height by 4 or multiply radius by 2
example
find current cup volume
V=(1/3)2.75pi1.375^2=2.2057291666666pi

if we times height by 4
3.5*4=14
V=(1/3)14pi1.375^2=8.822916666666666666pi

if we times radius by 2
1.375*2=5.5
V=(1/3)3.5pi5.5^2=8.822916666666666666pi


we can show it is 4 times by
8.822916666666666666pi/2.2057291666666pi= 3.99999 close enough
dimentions are

diameter of 2.75in and height of 11in or
 diameter of 5.5in and height of 3.5 in

The value of x and y in both equations
Vlada [557]
There is no solution to this set that works for both equations. If you multiply the top equation by 2 and then add them together, the x and y numbers will cancel. This leaves you with 0 =1010, which is never true.

Answer:

<em>The true statements are:</em>

<em>*The median weight for shelter A is greater than shelter B.</em>

<em>*The (IQR) interquartile range of shelter A is greater than the (IQR) interquartile range of shelter B.</em>

Step-by-step explanation:

<em>(for shelter A)</em>

median: 21

lowest value: 8

highest value: 30

lower quartile: 17

upper quartile: 28

(IQR) interquartile range: 28 - 17 = 11

Range: 30 - 8 = 22

<em>(for shelter B)</em>

median: 18

lowest value: 10

highest value: 28

lower quartile: 16

upper quartile: 20

(IQR) interquartile range: 20 - 16 = 4

Range: 28 - 10 = 18

~phew!, this took me long xd, hope this helps you~

I would highly appreciate it if you would mark me the brainliest~ :)
