Well let's see.

If the figure is split up into 10 pieces, then
each piece is 1/10 of the whole figure.

If 2 of the pieces are shaded, then
2/10 of the whole figure is shaded.

How many pieces are left ?

There were 10 pieces all together, and
2 of them are shaded. Hmmm. I think
there are probably (10 - 2) = 8 of them left
that are not shaded.

8 pieces makes 8/10 of the whole figure.

The tables show the battery lives (in hours) of two brands of laptops. Which brand's battery lives are more spread out? Explain

GalinKa [24]

Absolute Mad Deviation is used to see how spread out data is, you find the mean of data then subtract the mean from each number (absolute value) and then find the mean with the subtracted numbers.
Brand A MAD: 2.6925
Brand B MAD: 1.05
It’s Brand A :)
