​

Answer 1

Answer:

14

Step-by-step explanation:

14=14 so answer is 14

Answer 2

The average all 14 numbers is 6.86.

Explanation:

Formula for Mean :

Average = (Sum of observations) ÷ (Number of observations)

⇒ Sum of observations = Average x  (Number of observations)

Given : The average of 8 numbers is 6 and the average of another number 6 numbers is 8 .

Then, Sum of 8 numbers  = 6 x 8 = 48

Sum of another number 6 = 8 x 6 = 48

Sum of all 14 numbers = Sum of 8 numbers  + Sum of another number 6

= 48+48 =96

The average all 14 numbers = (Sum of all 14 numbers) ÷ 14

= 96 ÷ 14 ≈6.86

Hence , the average all 14 numbers is 6.86.
