Answer 1

Answer:

average age of 5 children is 12.12

Step-by-step explanation:

average = sum of observations/number of observations

sum of observations=12.6+13+12+11+12=60.6

number of observations=5

average=60.6/5

average=12.12

Answer 2

Answer:

Average of ages of 5 children = 12.12

Step-by-step explanation:

Given -

• Ages of 5 children = 12.6,13,12,11,12

ㅤ

To find -

• Average.

ㅤ

Solution -

To find the average, we'll follow to formula given below and solve further.

$\tt\red{Average=\frac{sum\:of\:observations}{number\:of\:observations}}$

ㅤ

$=\frac{12.6 + 13 + 12 + 11 + 12}{5} \\ \\ = \frac{12.6 + 13 + 12 + 11 + 12}{5} \\ \\ = \frac{60.6}{50} \\ \\ = 12.12$

ㅤ

So, average= $\tt\blue{12.12}$
