  1. GET YOUR CALCULATOR 5-17-13 EOG REVIEW DAY #5 EQ: What do you still need to review before EOG’s on the number system, ratios, proportions, expressions and equations? 7 / 2 0 18

  2. Check homework: To receive a 100, you must have all work completed.

  3. If the original amount goes up, it is a percent of increase Find the % of increase From 100 to 114 The percent of change is the amount, stated as a percent, that a number increases or decreases from the original amount. Amount of change Original amount % of change = If the original amount goes down, it is a percent of decrease Find the % of decrease From 1,500 to 1,416

  4. Focus Lesson Day 51 1. Find the change in fund raising that has gone from $400 last year to $650 this year.

  7. Find the percent of decrease from 60 to 48? A. 12%B. 15%C. 20%D. 31 %

  8. PERCENT ERROR Percentage Error is all about comparing a guess or estimate to an exact value.

  9. PERCENT ERROR Percentage Error is all about comparing a guess or estimate to an exact value. SAMPLE PROBLEM I estimated 260 people, but 325 came. Subtract approximate value from the exact value Take the absolute value. The error is 65 Divide the error by the exact value And make it a percentage:

  10. A man measured his height and found 6 feet. However, after he carefully measured his height a second time, he found his real height to be 5 feet.What is the percent error the man made the first time he measured his height? amount of error = 6 - 5 = 1The accepted value is the man's real height or the value he found after he carefully measured his height, or 5 So, percent error = 1/5=20%

  11. 12.5% -16.67% -10.71%

  12. Use review sheets for EE and Ratio and Proportions

  13. Play jeopardy EXIT TICKET: For the review skills: 3-Name three skills you are confident of. 2-Name two skills you are not sure about. 1-Name one skill you want to review. Homework: Handout
