8
13
17
Lowest value: 2
Highest value: 19
Median: 8
Lower quartile: 6
Upper quartile: 14
Range: Highest value - Lowest value = answer
Range: 19 - 2 = 17
Interquartile range: Upper quartile - Lower quartile = answer
(IQR) interquartile range = 14 - 6 = 8
So the answer to your question would be 8 :)

Okay, so we have the number 443,219. And we need to round to the nearest ten thousand.
443,219
The bolded number shows the ten thousands place. Now we need to know whether we round down, or round up. To decide which one to do, we need to look at the number in the thousandths place. The rule is...
If the number is 4 or less, then we round down. If the number is 5 or more then we round up.
In the number 443,219 the 3 is the number in the thousandths place.
Since 3 falls into the category of '4 or less', we know that we need to round down. So 443,219 becomes 440,000
Answer=440,000
If cold water pipe is turned on and hot water pipe is turned on 3 hours later then it will take 36 minutes (or 0.6 hr) to them to fill the pool together.
Step-by-step explanation:
Given :
Cold water pipe can fill a swimming pool in 4 hours, and a hot water pipe in 6 hours.
Solution :
Let's say the swimming pool is x gallons.
The flow rate of the cold water pipe is,
The flow rate of the hot water pipe is,
If the cold water pipe is turned on for three hours, the volume of water is:
The time to fill the rest of the pool with both the cold and hot water pipes is,
= 0.6 hr
If cold water pipe is turned on and hot water pipe is turned on 3 hours later then it will take 36 minutes (or 0.6 hr) to them to fill the pool together.

Answer:
0.6 hours
Step-by-step explanation:
Let's say the swimming pool is 12,000 gallons.
The flow rate of the cold water pipe is:
12000 gal / 4 hr = 3000 gal/hr
The flow rate of the hot water pipe is:
12000 gal / 6 hr = 2000 gal/hr
If the cold water pipe is turned on for three hours, the volume of water is:
3000 gal/hr × 3 hr = 9000 gal
That leaves 3000 gallons. The time to fill the rest of the pool with both the cold and hot water pipes is:
3000 gal / (3000 gal/hr + 2000 gal/hr) = 0.6 hr
It takes 0.6 hours (36 minutes).
