Question

charts and graphs end of lesson test
8 according to the graph, how many people have type a or type b blood?
chart: blood type | number of people: type a (6 red drops), type b (5 red drops), type ab (2 red drops), type o (7 red drops); key: 1 red drop = 5 people
multiple choice options: 6, 11, 30, 55
skip 7/10 complete

Explanation:

Step1: Determine number for Type A

Each drop is 5 people. Type A has 6 drops. So, \( 6\times5 = 30 \).

Step2: Determine number for Type B

Type B has 5 drops. So, \( 5\times5 = 25 \).

Step3: Sum Type A and Type B

Add the two results: \( 30 + 25 = 55 \). Wait, no, wait. Wait, the options have 55? Wait, no, maybe I miscalculated. Wait, the table: Type A has 6 drops, Type B has 5 drops. Each drop is 5 people? Wait, the image says " = 5 people" (the drop symbol). So Type A: 6 drops 5 = 30. Type B: 5 drops 5 =25. Then 30 +25 =55? But wait, the options: 6,11,30,55. Wait, maybe I misread the drop count. Wait, let's check again. Type A: how many drops? The image shows Type A with 6 drops? Wait, no, maybe the drop is 5 people? Wait, the user's image: " = 5 people" (the red drop). So Type A: 6 drops? Wait, no, looking at the table:

Type A: 6 drops (the red droplets), Type B: 5 drops, Type AB: 2 drops, Type O:7 drops.

So Type A: 6 5 =30, Type B:55=25. Then 30+25=55. So the answer is 55. Wait, but let's recheck.

Wait, maybe the drop is 5 people? Let's confirm:

Each drop (red droplet) represents 5 people.

Type A: number of drops =6, so 6*5=30.

Type B: number of drops=5, so 5*5=25.

Total for A or B: 30 +25=55.

Answer:

55
