Class Greeting

Objective: The student will be able to solve Mathematical Problems involving estimation techniques.

The percent that an estimate varies from an actual amount. Percent Error The percent that an estimate varies from an actual amount.

Vocabulary The percent error is: a ratio that compares the inaccuracy of an estimate, or the amount of error, to the actual amount. The proportion used to find the percent error is:

Ex 1) As a fundraiser, the Student Activities Council sold chances to guess the number of jelly beans in a jar. Brenda won the raffle with a guess of 370 jelly beans even though there were actually 400 jelly beans in the jar. What was the percent error? Subtract the guess and the actual value to find the amount of error. Answer: The percent error between Brenda’s guess and the actual amount is 7.5%.
