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 =

Answer:
- area: 36π ≈ 113.1 . . . . square units
- circumference: 12π ≈ 37.7 . . . . units
Step-by-step explanation:
The area formula is ...
A = πr^2
A = π(6^2) = 36π ≈ 113.1 . . . . square units
__
The circumference formula is ...
C = πd
C = π(12) = 12π ≈ 37.7 . . . . units
Answer:
98
Step-by-step explanation:
P(x) = 50 + 12x
P(4) = 50 + 12(4) = 50 + 48 = 98
Answer:
1/2 the jellybeans are yellow... or 25 jellybeans
Step-by-step explanation:
1/5 is the same thing as 2/10.
