Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive a. find how many donors had type b blood. Round to the nearest whole number if necessary
b. How many donors did not have type O blood? Round to the nearest whole number if necessary
c. Which blood type has less than 10 donors?
blood type percent
O 45
A 40
B 11
AB. 4

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 =

Type B blood donors ≈ 16

b. No. of blood donors without blood type O =

Those without blood type O ≈ 80

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

Type AB = ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
