Answer:
A. 60
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
We have to find:
n when 
. So
Dividing both sides by 3
We round up, so the correct answer is:
A. 60

The population after 8 years is 22752.P = 16,000 people
R = 4.5% or .045
t = 8 years</span>
By using the formula;
<span>16,000 x ( 1 + .045 )</span>⁸<span> = Y
16,000 x (1.045)</span>⁸<span> = Y
Y = 16,000 x 1.422 = 22752</span>
Answer:
4
Step-by-step explanation:
The common ratio is found by taking the second term and dividing by the first term
12/3 = 4
We can check by taking the third term and dividing by the second
48/12 = 4
The common ratio is 4
Multiply 1300 mm by 800 mm to get 1040000 mm. Then convert this to meters. 1 meter=1000 mm. Therefore, 1040000 mm is the same as 1040 meters.
You could also use 48 because 8 and 12 divide into it.
