4 0

Answer:

(0.095, 0.165)

Step-by-step explanation:

Confidence interval :

Phat ± margin of error

Margin of Error = 0.035

Phat = x / n

Phat = 11 / 85 = 0.1294117

Hence,

Phat ± 0.035

Lower boundary = 0.1294117 - 0.035 = 0.0944

Upper boundary = 0.1294117 + 0.035 = 0.1644

(0.0944, 0.1644)

Solve by unfolding: a0=2, and, n>=1, a_n=7a_n-1.
vodomira [7]
We are told that the first term is 2.  The next term is 7(2) = 14; the third term is 7(14) = 98.  And so on.  So, the first term and the common ratio (7) are known.

The nth term of this geometric series is a_n = 2(7)^(n-1).

Check:  What is the first term?  We expect it is 2.  2(7)^(1-1) = 2(1) = 2.  Correct.

What is the third term?  We expect it is 98.  2(7)^(3-1) = 2(7)^2 = 98.  Right.<span />

ad-work [718]
I'm pretty sure that you can not make these improper fractions; improper fraction just means the top number is bigger than the bottom. like 3/2 would be considered an improper fraction
