Answer:
The margin of error is of 0.01.
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 Z-table as such z has a p-value of 
.
That is z with a pvalue of 
, so Z = 1.037.
The margin of error is of:
In which 
is the standard deviation of the population and n is the size of the sample.
Standard deviation was 0.21.
This means that 
Sample of 450:
This means that 
What is the margin of error, assuming a 70% confidence level, to the nearest hundredth?
The margin of error is of 0.01.
You put the numbers you want to compare in a line with a space in the middle. the put
if the left is bigger and
if the right side is bigger.
The correct answer to this problem would be -3. Based on the points you've provided on the graph, -3 would be the correct common difference. :)
Answer:
area = 102 ft²
Step-by-step explanation:
(8x6) + (9x6) = 48 + 54 = 102 ft²
