That means Sam has 26 cookies.
32-6=26
A rectangular pyramid has 8 edges.
7 is a coefficient 4 is a constant
Tan(theta)= pi
Now, in order for you to find the angle (theta), you would inverse tan both the left and the right to find the value. The inverse of tan is tan^-1.
tan(theta)=pi ---> theta = tan^-1(pi)
Then, you would plug tan^-1(pi) into a calculator, giving you the value
1.26
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.
