I have an expression

floating around in my head; let's see if it makes sense.
The variance of binary valued random variable b that comes up 1 with probability p (so has mean p) is

That's for an individual sample. For the observed average we divide by n, and for the standard deviation we take the square root:

Plugging in the numbers,

One standard deviation of the average is almost 2% so a 27% outcome was 3/1.9 = 1.6 standard deviations from the mean, corresponding to a two sided probability of a bit bigger than 10% of happening by chance.
So this is borderline suspect; most surveys will include a two sigma margin of error, say plus or minus 4 percent here, and the results were within those bounds.

Answer:
12^x
Step-by-step explanation:
Absolute. Value. Of. |12^x-8|. Is. 12^x + 8
12^x + 8= 2^3. So. 12^x. +8.=8
12^x+8-8=8-8
12^x=0. Left. With. 12^x?
