Worked examples

Start with worked Grade 12 examples

These original examples introduce selected Math 30-3 expectations. The full expectation map is not a complete set of published written lessons or a substitute for official course materials and assignments. The strand-prefixed labels below identify the matching Ontario specific expectations; titles are concise study-guide paraphrases.

1. A measured part

A part is specified as 50.0 ± 0.2 mm. Is a 50.1 mm reading within tolerance?

Worked method: The permitted interval is 49.8–50.2 mm, so 50.1 mm is within tolerance.

فارسی · توضیح مثال

اندازهٔ مجاز قطعه ۵۰٫۰ ± ۰٫۲ میلی‌متر است. آیا اندازهٔ ۵۰٫۱ میلی‌متر مجاز است؟ بازهٔ مجاز ۴۹٫۸ تا ۵۰٫۲ میلی‌متر است؛ پس ۵۰٫۱ میلی‌متر مجاز است.

2. A single-event chance

In a hypothetical batch of 20 parts, 3 are defective. What is the observed defective proportion?

Worked method: 3/20 = 0.15 = 15%; this batch proportion is not a universal defect rate.

فارسی · توضیح مثال

در یک دستهٔ فرضی ۲۰ قطعه‌ای، ۳ قطعه معیوب است. نسبت مشاهده‌شدهٔ معیوب‌ها چقدر است؟ ۳/۲۰ = ۰٫۱۵ = ۱۵٪؛ این نسبت یک دستهٔ فرضی است، نه نرخ خرابی عمومی.

Try independently, then check

Write your own solution before opening each answer. If a step is unclear, review the matching expectation or a Grade 11 prerequisite.

Practice 1

What is the upper limit of 12.0 ± 0.3 cm?

Show worked answer

12.3 cm.

فارسی · تمرین و پاسخ

کران بالای ۱۲٫۰ ± ۰٫۳ سانتی‌متر چیست؟ ۱۲٫۳ سانتی‌متر.

Practice 2

What is the median of 2, 4, 9, 11, and 14?

Show worked answer

9.

فارسی · تمرین و پاسخ

میانهٔ ۲، ۴، ۹، ۱۱ و ۱۴ چیست؟ ۹.

Mathematical processes across expectations

These processes are practised throughout the course, rather than listed as separate lessons.

  • Draw, label, and verify a practical diagram before calculating. (پیش از محاسبه، نمودار کاربردی را رسم، برچسب‌گذاری و بررسی کنید.)
  • Keep units and assumptions visible in workplace and financial problems. (واحدها و فرض‌ها را در مسئله‌های کاری و مالی آشکار نگه دارید.)
  • Check whether a numerical answer makes sense in the stated context. (معنادار بودن پاسخ عددی را در موقعیت داده‌شده بررسی کنید.)

Sources and editorial process

Curriculum-aligned and reviewed before publication

This independent study guide follows the official course source. It is not an official government, school, or university publication.

Lessons may be AI-assisted or editorially prepared. Published content is checked for structure, notation, calculations, course boundaries, and readability before release. Because corrections can still be necessary, readers can report a problem.
