<span>This is true. Because we don’t have more precision our of 6.3, we cannot append more digits with any certainty. We must omit the digit in the hundredths place in order to have a solutionwith correct precision using significant figures.</span>
They are supplementary and adjacent
<span>The vertex form of a quadratic is given by. y = a(x – h)2 + k, where (h, k) is the vertex. The "a" in the vertex form is the same "a" as. in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.</span><span>

I don’t understand this but:
The mean is the average of all the numbers combined
the median is the number centered directly in the middle with the same number of numbers on both sides of the number in the middle
The mode is how many times a number appears
