The answer is A because of the bar graph
Answer:
Step-by-step explanation:
3/4c=5/9
C=5×4/9×3
C=20/27
Since we are asked to find per capita, therefore this
means that we have to simply divide the total number of televisions by the
total US population. Therefore:
tv per capita = 6 million / 152.3 million
<span>tv per capita = 0.03940</span>
Answer:
The margin of error for a confidence interval for the population mean with a 90% confidence level is 0.53 hours.
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.
In this quesstion:
So
The margin of error for a confidence interval for the population mean with a 90% confidence level is 0.53 hours.
Answer: A) Corresponding Angles
Refer to the diagram below.
Two angles are corresponding to each other when they are on the same line that crosses two parallel lines, one angle is inside the parallel lines, the other is on the outside.
