Opal is collecting data on water levels in different parts of town. She notices that her sample data has a low-value outlier. The statement which must be true is that removing the outlier will decrease the spread of the graph of the data set.
To simplify the expression we proceed as follows:
<span>d^2+4d+3/d^2-7d-8 + d^2-2d-8/d^2+5d+6
putting like terms together we have:
(d^2+d^2)+(4d-7d-2d+5d)+(3/d^2-8/d^2)+(-8+6)
=2d^2+0d-5/d^2-2
=2d</span>²-5/d²-2
Answer: 2d²-5/d²-2
