You would think it was 3 * 12 = 36. Not so. All polygons have to be broken down into some figure that will give 2 dimensions that are at right angles to each other. That would mean that
d1 * d2 = Area for the small polygon
3d1 * 3d2 = area of the larger polygon
What that means is that the area of the larger one is 9 times the smaller one.
Area large = 12 * 9 = 108 square units. <<<<< answer.
If you find this hard to be leave try it with a square.
Suppose you have a square (the small one) that is 3 cm by 3 cm
The small one has an area of 3*3 cm^2 = 9 cm
Now you have another square that is 3 times larger. That means that each side is 3*3 = 9
So s = 9
Area = s^2
Area = 9^2 = 81 cm^2
81 is 9 times larger than 9 just as you would think.
100,000 - 63,482= 36,518.

Answer:
The 95% confidence interval for the mean change in blood pressure,
, is 1.744 <
< 2.816
Step-by-step explanation:
The parameters given are;
The number of people in the sample, n = 9
The average drop in blood pressure,
= 2.28 points
The standard deviation, σ = 0.82
The confidence level = 95%
The formula for confidence interval with a known mean is given as follows;

Where:
= z - score at 95% confidence level = 1.96
We therefore have;

Which gives the 95% confidence interval for the mean change in pressure,
, is given as follows;
1.744 <
< 2.816
I believe that is C. Statistical question.
I know it’s not B because that has nothing so do with the question so you’re good there. While A could be a potential answer, it says a question that can be answered by collecting data, whereas the mean would actually be that data and not the question that can be answered so C would be the only choice left.
