Answer: = 
Step-by-step explanation:
The confidence interval for population proportion(p) is given by :-
(1)
It is also written as : 
(*)
The given confidence interval for population proportion :
(2)
Comparing (1) and (2) , we get
Lower limit = 
(3)
Upper limit = 
(4)
Adding (3) and (4) , we get
Put value of 
in (2) , we get
Put values of and E= 0.111 in (*) , we get
Required form =
Formula for P: P = 2W + 2L
Formula for A: A = WL
Here, P = 2(4 ft) + 2(7 ft) = (8+14) ft = 22 ft
and A = (4 ft)(7 ft) = 28 ft^2
Hello there! So the speed goes up in 6 seconds, maintains for 8 seconds, and then holds for 20 seconds. When something is resting, the line stays straight horizontally for that 20 seconds. B and C are eliminated, because there is no break for C and B does not show the speed accurately. Really, the fish would speed up to 2.5 m/s in 6 seconds, then it maintains that speed, and slows down. D shows a constant speed, which the speed isn't constant, so D is out. A is the only one that represents the scenario properly. The answer is A.
