Answer:
b. 0.055
Step-by-step explanation:
The point estimate of the proportion of people who wear hearing aids is
The number of people in the sample who wear hearing aids divided by the total number of people in the sample.

Step-by-step explanation:
Answer:
(x+6)(x+6)
(x+6)^2
Always remember this identity
(a+b)^2 = a^2 + b^2 + 2ab
So, Now take x=a , 6 =b
Substitute above values
x^2 + 36 +2(x)(6)
=x^2 +36 +12x
=x(x+12) +36
