Answer:
The series diverges
Step-by-step explanation:
First, let's find the sequence:

As we can see, they are multiples of 4, so one possible sequence is:

Hence, we can represent the series as:

Let's use the zero test which states:

So:

Therefore, by the zero test, the series diverges
Answer:
A =
. r^2
If A = 9
ft^2
. r^2 = 9
ft^2
r^2 = 9ft^2
r = sqrt(9ft^2)
r = 3ft ( r>0)
Step-by-step explanation:
Answer:
The critical value for the 90% confidence interval is
.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of
.
90% confidence level
So
, z is the value of Z that has a p-value of
, so
.
The critical value for the 90% confidence interval is
.
I have no idea
I just need points for an answer sorry
