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.
We are working with completing ratios.
So we have the initial ratio 1:40.
We need to solve 6:x
What we do to one side of a ratio, we have to do to the other so it is even.
We multiplied the blueprint by 6, so we need to multiply the other side.
6×40
240
So, the actual length is 240 in (not sure if that is the unit of measurement since it is not listed).
In that 16 minutes, the amount that leaks out is (8 - 6) = 2 gallons.
The average unit rate of the leak is
(2 gal)/(16 min) = (2/16) (gal/min) = 1/8 gal/min
= 16 fluid ounce per min
= 4/15 fl oz per second
