Answer:
Can you maybe elaborate the question with the help of brackets I guess ...?
It is difficult to understand the question this way .
Answer:
0.85 ( lowest value proportion to vaccinate )
Step-by-step explanation:
Using the herd immunity relationship
Vc = E - ( E / Ro )
Vc = critical vaccination level
E = vaccine effective against the transmission = 1
Ro = Basic reproduction number
lets assume the effectiveness of the transmission = 100% = 1
lets assume the
Vc = 1 - ( 1 / 3 ) = 67%
but the lowest value proportion to vaccinate = 85%
It’s might be D

Answer: 5/2 decimal form 2.5
Step-by-step explanation: −y+5.3+7.2y−9
=−y+5.3+7.2y+−9
Combine Like Terms:
=−y+5.3+7.2y+−9
=(−y+7.2y)+(5.3+−9)
=6.2y+−3.7
=5/2 decimal form 2.5
