Answer:
mean of first five natural no.
1,2,3,4,5
by making the table
Step-by-step explanation:
The mean of first five average numbers :
The mean of first five average numbers :The first five natural numbers = 1 , 2 , 3 , 4 , 5
The mean of first five average numbers :The first five natural numbers = 1 , 2 , 3 , 4 , 5Their quantity = 5
The mean of first five average numbers :The first five natural numbers = 1 , 2 , 3 , 4 , 5Their quantity = 5Mean = Sum/quantity
The mean of first five average numbers :The first five natural numbers = 1 , 2 , 3 , 4 , 5Their quantity = 5Mean = Sum/quantity = 1+2+3+4+5/5
The mean of first five average numbers :The first five natural numbers = 1 , 2 , 3 , 4 , 5Their quantity = 5Mean = Sum/quantity = 1+2+3+4+5/5 = 15/5
The mean of first five average numbers :The first five natural numbers = 1 , 2 , 3 , 4 , 5Their quantity = 5Mean = Sum/quantity = 1+2+3+4+5/5 = 15/5 = 3
The mean of first six natural odd numbers :
The required numbers = 1 , 3 , 5 , 7 , 9 , 11
Quantity = 6
Mean = Sum/Quantity
= 1+3+5+7+9+11/6
= 36/6
= 6
For the rest questions there is no data about the marks of the students
