Answer:
Rule of 9 : an integer is divisible by 9 if and only if the sum of its integers is divisible by 9.
Proof :
Let us consider a number x such that,
Where, 
are the the digits of the number x,
So, we can write,
Let,
Since, a number is in the form of 
, where k is an positive integer, is always divisible by 9,
⇒ 
are divisible by 9.
⇒ x-S is divisible by 9,
⇒ If S is divisible by 9 ⇒ x must divisible by 9,
Or if x is divisible by 9 ⇒ S must divisible by 9.
Hence, proved...

Answer:
Median: 36 and 1/7
Mode: 45
Range: 25
Step-by-step explanation:
33 + 45 + 38 + 27 + 45 + 20 + 45
253 ÷ 7 = 36 and 1/7
1 33
3 45s
1 38
1 27
1 20
The mode is 45.
Largest number: 45
Smallest number: 20
45 - 20 = 25
