In interval notation it should be [6, ∞)
Answer:
[0, 6) ∪ [65, ∞)
Step-by-step explanation:
Ages under 6 will be in the interval [0, 5], or in the interval [0, 6), as you may wish.
Ages 65 or older will be in the interval [65, ∞).
The union of these two intervals is ...
[0, 6) ∪ [65, ∞)
A page of two-dimensional arrays can be thought of as a three-dimensional array. Since 2-dimensional arrays are commonly expressed in tables or matrixes, therefore, if we put these tables or matrices in a page, the collection of matrices in a single page would now be structured into a 3D array.
