Mrs. Alberts has two seventh grade math classes this year. They took their final exam, and Mrs. Alberts just finished grading th
em. She made a box-and-whisker plot for each class in order to compare their results.
Analyze the box-and-whisker plots from above and then select the following comparative inferences that are true. Select all that apply.
1. The interquartile range of Class A is about twice as large as the interquartile range of Class B.
2. There is very little overlap in the two data sets.
3. The median of Class A is about 5 points higher than the median of Class B.
4. The range of Class B is about 12 points less than the range of Class A.
5. A student in Class B had the highest score of both classes.
6. In general, the students from Class B scored better than the students from Class A.

Answer:
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into and
?
It is
2 - What is the highest degree of that divides evenly into
and
?
It is 1, since is not in every term.
3 - Multiplying the results above,
The GCF is 4.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3) Simplify each term in parentheses.
4) Factor out common terms in the first two terms, then in the last two terms.
5) Factor out the common term .
Answer:
Step-by-step explanation:
Given : The formula for the area of a trapezoid with altitude k and bases m and n is
We have solve for m .
Consider the given formula
Multiply both side by , we have,
Now subtract n both side, we have,
Thus,
