Answer:
4.58
Step-by-step explanation:
21 is not a perfect square, but lies between the perfect squares 16 and 25. Thus, √21 lies between √16 and √25, that is, between 4 and 5. Since 21 is closer to 25 than to 16, √21 is closer to 5 than to 4. A rough estimate of √21 would be 4.7.
√21 done on a calculator comes out to 4.58.

Answer:
C. The total number of movies watched categorized by science fiction vs. non-science fiction
Step-by-step explanation:
A stacked bar chart is a type of graph that is mostly used to simplify multiple parts and compare them as a whole.
It uses different "bars" and each bar represents one part of the whole and segments of that bar show the different parts or categories of the whole.
Consider option A
In this option, the total average height of men and women cannot be considered as a whole. Therefore, the stacked chart cannot be used.
Consider option B
In this option, the totak number of red cars and bicycles cannot be considered as a whole because cars and bicycles are two different kinds of sets.
Consider option C
Here, the total number of movies watched categorized by science fiction and non-science fiction can be considered a whole because science and non-science fiction movies are the same sets of data and they add up to the total number of movies.
Hence, a stacked graph is appropriate here.
Option C is the correct answer
