but dude what to answer............
Answer:
0.81
Step-by-step explanation:
Herd immunity or community immunity is the immunity seen after vaccination of a population wherein the large portion of the population becomes immune to the pathogen. It depends on vaccine efficacy and vaccination rate.
The reproduction number R_o is a factor indicating the number of people that can be infected by the person with the disease. If Ro=5 then one infected person can infect 5 people with Polio virus.
V_c= q_c/E
V_c= Vaccine coverage
q_c= herd immunity threshold
E= Vaccine efficacy= 99%=0.99
V_c= q_c/E
V_c= 0.8/0.99= 0.808= 0.81
Thus, 81% coverage or vaccination for Polio is required to stop spread of Polio in the population.
The sum of the prime numbers 2, 5, and 61 is 68.
Number 6 is {{{y=4x^3 - 7}}} solve for x
{{{4x^3=y+7}}}
{{{x^3=(y+7)/4}}}
{{{x=root(3,(y+7)/4)}}}
{{{f^(-1)=root(3,(x+7)
