Answer: Option D
D. 41
Step-by-step explanation:
A value is considered an outlier if
or
Where
is the third quartile
is the first quartile
IQR is the interquartile range.
In this case:
So
Then the outlier values will be all those greater than 122 or less than 42
Therefore the answer is the option D.
-92
Step-by-step explanation:
If a quadratic equation has the following form:
then its discriminant D is defined as
In our given quadratic equation, a = 4, b = -2 and c = 6, so its discriminant is
Note: The value of the discriminant D will determine the characteristics of the roots of the quadratic equation according to the following rules:
there will be 2 real roots
there will be 1 real root
there will be 2 imaginary roots
Hence our given quadratic equation will not have any real roots but only imaginary ones.
