Question

Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive

Answer 1

Answer:

a. 16

b. 80

c. Blood type AB

Step-by-step explanation:

Given:

O = 45%

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood = $\frac{11}{100}*145 = \frac{1,595}{100} = 15.95$

Type B blood donors ≈ 16

b. No. of blood donors without blood type O = $\frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75$

Those without blood type O ≈ 80

c. Find the number of people that had type AB:

Type AB = $\frac{4}{100}*145 = 5.8$ ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.
