360° = 120° + 10x + 4x + y
360° = 120°<span> + 14x + y
</span>240° = <span>14x + y
</span>240° - <span>14x = y
</span>
That's all I can do
Answer:
First 12 natural numbers are: 1,2,3,4,5,6, 7,8,9,10,11 abs …. 12. Now, substitute 78 for the sum of observations and 12 for the total number of observations in the formula M=Sn to determine the arithmetic mean. Hence, 6.5 is the arithmetic mean of the first 12 natural numbers.
