What is the IQR of <br>15,19,20,25,25,28,29,30,30,35,37,43<br>

Answer:
IQR = 10.
Step-by-step explanation:
15,19,20,25,25,28,29,30,30,35,37,43
There are 12 numbers in the list so the median is the mean of 28 and 29,
The lower quartile is the mean of the 3rd and 4th numbers and the upper quartile is the mean of the 9th and 10th numbers.
Lower quartile = (20+25) / 2 = 22.5.
Upper quartile = (30 + 35) / 2 = 32.5.
So the IQR = 32.5 - 22.5 = 10.
Answer:
3/32 tons
Step-by-step explanation:
3/4 divided by 8
3/4 divided by 8/1
3/4 times 1/8
3/32 tons per flower pot
16 + 4 = 20
16/20 = 80% or 4/5 (20 x 5 = 100, 16 x 5 = 80)
4/20 = 20% or 1/5 (20 x 5 = 100, 4 x 5 = 20)
The relationship is that more students do not prefer school uniforms compared to the ones that do prefer them.
Hope this helps!
