Answer:
a = 4.762203156
Step-by-step explanation:
Given:
ab^4 = 12 and a^5b^5 = 7776
Making the equations a subject of a;
a = 12/b^4 and a^5 = 7776/b^5
Finding fifth root on both sides of equation two;
a =
/b
You will get a = 6/b
Equating the two equations;
12/b^4 = 6/b
Multiplying both sides by b^4 gives:
b =
= 1.25992105
We had that a = 12/b^4 so;
a = 12/1.25992105^4 = 12/2.5198421 = 4.762203156

Answer:
Sample size is 
Step-by-step explanation:
Given that,
Margin of error
%
Confidence level
%
Suppose, sample proportion
i.e. 
We know that,
Margin of error 
∴ 





squaring on both side,
∴ 
Hence, the sample size is,

Hence, the correct option is
