Answer:
In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line (or alternatively, a quantity that can be represented as an infinite decimal expansion).
To answer this, we will look at simple definitions of each term. From the definitions, it will be clear which one is correct.
<u>What is mode?</u>
It is the most occurring number.
<u>What is interquartile range?</u>
It is the difference between third quartile and first quartile.
<u>What is range?</u>
It is largest number minus the smallest number.
<u>What is mean absolute deviation (MAD)?</u>
It is the average distance of each data point from the mean.
<u>What is a quartile?</u>
It is one of the four groups in which a dataset is divided.
From the simple definitions of each term, we can clearly see that Mean Absolute Deviation (MAD), answer choice D, is the correct answer.

C=x+9, c+x=99, c=99-x
So we have two equations equal to c, c=x+9 and c=99-x, since c=c:
x+9=99-x
2x+9=99
2x=90
x=45, and since c=x+9, c=54
So Charlie weighs 54 kg and his brother weighs 45 kg.
