8 STAR CITY Open-Response / Geometry / Review for Target Test #2b Name Teacher Period GEOMETRY OPEN-RESPONSE ITEM A A. Human blood is often classified according to whether three antigens, A, B, and Rh, are present or absent. Blood type is stated first in terms of antigens A and B: blood containing only A is called type A, blood containing only B is called type B, blood containing both A and B is called type AB, and blood containing neither A nor B is called type O. The presence or absence of Rh is indicated by adding the word positive (present) or negative (absent) or its corresponding symbol ( + or ). The table below shows the eight blood types that result and the percentage of people with each type in the U.S. population. Blood Type Percentage of Population A positive 34 % B positive 9 % AB positive 3 % O positive 38 % A negative 6 % B negative 2 % AB negative 1 % O negative 7 % 1. Complete the Venn diagram on the Student Answer Document. Label each region with its blood type (include positive or negative) and percent of the population. 2. Blood type O is known as the Universal Donor, meaning that anyone can receive this blood type. What percent of the population can receive this blood type? Show or explain your work. 3. Blood type AB + is known as the Universal Recipient, meaning that anyone can donate blood for a person with this blood type. However, blood type AB can only give blood to type AB. For what percent of the population can type AB be a donor? Show or explain your work. BE SURE TO LABEL YOUR RESPONSES (1), (2) AND (3). 8

11 Score RUBRIC FOR GEOMETRY OPEN-RESPONSE ITEM A (LG.1.G.1C) Description 4 The student earns 5 points. All explanations are clear and correct. 3 The student earns points. 2 The student earns points. 1 The student earns points. OR The student demonstrates minimal understanding of representing data in a Venn diagram. 0 No understanding. Work is either incorrect or irrelevant. B Blank. - No response. - No attempt to answer item.

12 Solution and Scoring Scoring: Part 1: Score 3 points for completing the Venn diagram correctly and properly identifying each region with its type and percentage. OR Score 2 points for completing the Venn diagram with percentages, but the labels are missing or incomplete. OR Score 1 point for placing at least 5 of the percentages in the proper location with correct labels. Part 2: Score 1 point for correctly calculating the percent of the population that receives blood type O with work shown. OR Score ½ point for calculating the percent of the population that receives blood type O with calculation error or no work shown. Part 3: Score 1 point for correctly calculating the percent of the population that blood type AB is a donor with work shown. OR Score ½ point for calculating the percent of the population that blood type AB is a donor with calculation error or no work shown. Solution: Part 1: Part 2: 100 % of the population can receive blood type O. 34% + 9% + 3% + 38% + 6% + 2% + 1% + 7% = 100%

13 Part 3: Type AB can only give blood to those who have type AB + or AB blood, which is 4% of the population. 3% + 1% = 4%
