Final answer:
The high school level question in mathematics asked about a piecewise function k(x) with different criteria based on the value of x, but it lacks sufficient context and thus cannot be solved as presented.
Step-by-step explanation:
This question falls under the subject of Mathematics, more specifically in the topic area of piecewise functions and the basics of probability. The student is given a piecewise function k(x) that has different values depending on the interval in which x falls. There isn't enough context to solve for a specific value since the provided scenarios seem disconnected. However, a general approach would involve identifying the correct interval for a given value of x and then using the relevant equation for k(x) within that interval to find the value of k.
