Answer:
2.5
Step-by-step explanation:
y=kx, k is constant of prop
Answer:
B
Step-by-step explanation:
A geometric series will only converge if the common ratio r meets the requirement
- 1 < r < 1
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
All terms inside the summation are of this form
The only one with - 1 < r < 1 is B where r =
= 0.75
Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
Z is the zscore that has a pvalue of
.
For this problem, we have that:

90% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 90% confidence interval is 0.575 to 0.625.
<span>2, 4, 8, 16, –32, 64, …
Common ratio = 4/2 = 2
16/8 = 2
But -32/16 = -2.
The ratio is not constant, hence it is not a geometric.
D. The sequence is not a geometric sequence.</span>
