Recursive Rules in Grading

The video tutorial explains how a paper's grade decreases by 10 points for each day it is late. It introduces the concept of a recursive rule to calculate the grade on any given day. The recursive formula is defined as a_subn = a_subn-1 - 10, where a_subn represents the grade on day n, and a_subn-1 is the grade from the previous day. The tutorial demonstrates how to apply this rule to determine the grade for any day the paper is submitted.

What happens to a paper's grade for each day it is submitted late?

• It remains the same.

• It decreases by 10 points.

• It is doubled.

• It increases by 10 points.

What is the purpose of a recursive rule in this context?

• To calculate the initial grade of the paper.

• To find the average grade of all papers.

• To determine the grade of the paper on any day based on the previous day's grade.

• To increase the grade by 10 points each day.

Which of the following best describes a recursive rule?

• A rule that repeats itself based on previous outcomes.

• A rule that increases the grade over time.

• A rule that applies only once.

• A rule that is used to calculate the final grade only.

How is the grade of a paper on a given day calculated using the recursive rule?

• By subtracting 10 from the previous day's grade.

• By dividing the previous day's grade by 10.

• By adding 10 to the previous day's grade.

• By multiplying the previous day's grade by 10.

If a paper was graded 90 on the first day, what would be its grade on the third day if it was not submitted?

• 70

• 60

• 80

• 50
