45-46:50

I’m not sure what “45-46:50” refers to. Do you mean problems 45, 46, and 50 from a textbook or worksheet? If you can share the exact problem statements (or tell me the course and topic), I’ll solve them step-by-step.

If you can’t paste them, I can still help by:

• Giving a quick topic recap for likely areas (e.g., calculus, linear algebra, statistics) and
• Providing a fresh set of practice problems with full solutions.

Let me know:

• Which course and which topics are covered by problems 45, 46, 50?
• Do you want full worked solutions or only final answers with brief explanations?
