Answer:
15
Step-by-step explanation:
Let the added number be x
Data set is
9,12,17,15,13
After adding x data set will be,
x,9,12,17,15,13
Number of digits=6
6 is an even number
Arrange the following number in ascendig order
9,12,13,x,15,17
Hence, the median will be=[(n/2)+(n/2
+1)]÷2
Hence, the median will be=[(6/2) th term+(n/2
+1) th term]÷2
Hence, the median will be= (3 th term +4 th term)÷2
=
=14
13+x=14×2
13+x=28
x=28-13
x=15
Hence, the added number is 15.

Answer:
The candle must burn at 2cm per hour in order to be 6cm tall after 4 hours. I know this because the candle has to burn 8cm in 4 hours and that amounts to 2cm per hour.
Step-by-step explanation:
Lets solve!
We have to find out how much of the candle needs to be burned!
14cm - 6cm = 8cm
The candle must burn 8cm in 4 hours!
Lets find out how much the candle burns in 1 hour.
= 2cm per hour
