Answer:
The combined standard deviation is 1.58114.
Step-by-step explanation:
The formula to compute the combined standard deviations of two different data sets is:
Here is the combined mean given by:
It is provided that the sample size is same for both the data sets, i.e.
Compute the combined mean as follows:
Compute the combined standard deviation as follows:
Thus, the combined standard deviation is 1.58114.
The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,
Thus the option H is the correct option.
To find the correct proportion we need to know about the properties of slimier polygon.
<h3>What are the properties of similar polygon?</h3>Two polygons are said to be similar or congruent pentagon-
The corresponding angle of two pentagons are congruent.
The ratio of corresponding sides is same for all the sides.
The figure given in the problem of similar two polygons with six sides.
Rearrange the second figure as shown in figure.
As for the similar polygons, the ratio of corresponding sides is same for all the sides.
Thus the sides shown in the two rearranged figure must be same. Therefore,
Hence the correct proportion is,
Thus the option H is the correct option.
