Question

find the mean of composite numbers less than 20​

Answer 1

Answer:

11.2

Step-by-step explanation:

Composite numbers below 20 are:-

4, 6, 8, 9, 10, 12, 14, 15, 16, 18

Mean = Sum of quantities/No. of quantities

= 112/10

= 11.2

Answer 2

The mean of the composite numbers less than 20 is 11.2.

Given,

Composite numbers less than 20.

To Find,

The mean of these numbers.

Solution,

The composite numbers less than 20 are

4, 6, 8, 9, 10, 12, 14, 15, 16, 18

Now, the formula for calculating the mean is

Mean = sum of observations/Total number of observations

Here,

Sum of observations = 4+6+8+9+10+12+14+15+16+18 = 112

Total number of observations = 10

So,

Mean = 112/10 = 11.2

Hence, the mean of the composite numbers less than 20 is 11.2.
