Answer:
The complement of the given set in interval notation is
. It can we written as (-inf,5]U(6,inf).
Step-by-step explanation:
The given set in interval notation is
(−5,6]
It means the set is defined as

If B is a set and U is a universal set, then complement of set B contains the elements of universal set but not the elements of set B.
Here, universal set is R, the set set of all real numbers.

The complement of the given set is


Complement of the given set in interval notation is
![A^c=(-\infty,-5]\cup(6,\infty)](https://tex.z-dn.net/?f=A%5Ec%3D%28-%5Cinfty%2C-5%5D%5Ccup%286%2C%5Cinfty%29)
Therefore the complement of the given set in interval notation is
. It can we written as (-inf,5]U(6,inf).
8 hours is 8*60=480 minutes, so our ratio is 169/480 as a fraction, or 169:480 as a ratio. This is already in lowest terms.
