To simplify, we can use the FOIL method. That stands for first, outer, inner, last. What we do is take two factors at a time and multiply the first terms by each other, the outer terms together, etc.
Let's start with (2x-1) and (x+5)
First: 2x * x = 2x^2
Outer: 2x * 5 = 10x
Inner: -1 * x = -x
Last: -1 * 5 = -5
2x^2 + 9x - 5
Now FOIL this result with (3x - 2)
6x^3 - 4x^2 + 27x^2 - 18x - 15x + 10
Simplify:
6x^3 - 23x^2 - 33x + 10
Answer:
D. There is no association because the distribution of genre preferences is the same among the grade groups
Explanation:
Based on this graph, we can conclude that there is no association between grade and genre preference, because the distribution of genre preferences is the same among the grade groups
.
We can see that the 9th and 11th graders have a slightly higher preference for fiction than the 10th and 12th graders. However, this difference is barely noticeable and doesn't affect the conclusion. Most students from every grade prefer fiction to nonfiction, so we can conclude that the genre preference is the same among the grade groups
