Question

Find the range and the arithmetic mean of first ten odd numbers

Answer 1

Answer:

10,18

Step-by-step explanation:

Arithmetic mean of first 10 odd numbers is,

The first 10 odd numbers are,

1,3,5,7,9,11,13,15,17,19.

so,

Arithmetic mean=sum of all observations/Total no.of observations.

Arithmetic mean=1+3+5+7+9+11+13+15+17+19/10

Therefore, Arithmetic mean

=100/10 =10.

Arithmetic mean of first 10 odd numbers=10

Range of first 10 odd numbers=maximum number- minimum number.

Therefore,Range of first 10 odd numbers= 19-1=18.

Answer 2

Answer:

10 and 18 is the answer

Step-by-step explanation:

1st 10 odd numbers are

1,3,5,7,9,11,13,15,17,19

arithmetic mean = sum of observation/no of observation

1+3+5+7+9+11+13+15+17+19/10

=100/10

=10 ans

range=highest value - lowest value

= 19-1

=18
