People with kids or babies always want them to eat natural foods with no preservation, even if are a bit more expensive than the other available options.What they care about is the quality and health of the kids.So keeping this point in head,most of the brands uses the technique to compete with the other in-market brands. And that's what the shopkeeper did in this case.
Mike should have read the listed ingredients on the baby food jar.I think both of them would have the same,except a few.
The answer is B.
There are no outliers that will make the mean invalid.
The median is also good. It will give you an answer close to the average.
X^4=256
x^4-256=0
(x^2)^2-(16)^2=0
(x^2+16)(x^2-16)=0
either x^2+16=0
it gives complex roots.
or x^2-16=0
or x^2-4^2=0
(x+4)(x-4)=0
either x+4=0,x=-4
or x-4=0
x=4
It's 56 and 72 because 56/8=7 and 72/8=9
