Answer:
9 students
Step-by-step explanation:
1) Factor out the coefficient 2: 2x^2+12x=4 => 2(x^2 + 6x) = 4
2) Complete the square of x^2 + 6x: x^2 + 6x + 9 - 9. Then:
2(x^2 + 6x + 9 - 9) = 4
3) Rewrite the square as the square of a binomial:
2( [x+3]^2 - 9) = 4, or
2([x+3]^2) = 22, or
2( [x+3]^2 ) - 22 = 0
The value of q is -22.
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
