Final answer:
An array partitioned around the number 5 would have elements less than 5 on one side and elements greater than 5 on the other, with 5 serving as the pivot point. The position of the fifth dot mentioned in relation to perpendicular hash marks does not pertain to the array partitioning concept without further context.
Step-by-step explanation:
When we talk about arrays and partitions around a number, this often refers to the process of arranging elements in an array so that all elements less than a certain value are on one side, and all elements greater than that value are on the other side. In the context of this question, which asks about a partition around the number 5, an example array could look like the following:
Here, numbers 1 through 4 are less than 5 and are placed on one side, while numbers 6 through 8 are greater than 5 and are placed on the other side, with 5 being the pivot point around which the partition is constructed. It's important to note that the exact position of the number 5 doesn't necessarily need to be in the middle of the array; it simply acts as the dividing or pivot point.
The provided information about the fifth dot and its relation to perpendicular hash marks do not clearly relate to the concept of partitioning in arrays, but rather seems to reference a specific diagram or graph that is not included. Therefore, that part of the question cannot be directly addressed without additional context.
