All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure<span> of the angles, we know that the </span>sum<span> of all the angles is 1080 degrees (from above)... And there are eight angles... So, the </span>measure<span> of the interior angle of a regular </span>octagon<span> is 135 degrees</span>
Answer: Letter Choice ( B): -x^2 - 4x + 7
Step-by-step explanation:
( 4x^2 - 7x + 9 ) - ( 5x^2 - 3x + 2 )
Remove Parentheses: (a) = a
4x^2 - 7x + 9 - ( 5x^2 - 3x + 2 )
- ( 5x^2 - 3x + 2 ): - 5x^2 + 3x - 2
Simplify:
4x^2 - 7x + 9 - 5x^2 + 3x - 2
Answer:
Letter Choice ( B ):
-X^2 - 4x + 7

6.to find the answer you have to multiply 1300*5=6500 then 6500+450=6950

Answer: Choice C) No more than 25% of the data for the sets overlap
================================================
Explanation:
It sounds like you are given a visual representation of the box plots. However, for reference, I'm going to post an attached image of the plots so we're both on the same page. See the image below.
Figure 1 and Figure 2 both refer to the same set of boxplots. The only difference is that figure 2 has a blue region from x = 20 to x = 23 to show where the two boxplots overlap.
Since this blue region does not contain a full whisker, and only a fraction of one for each plot, this means that less than 25% of the data is overlapping between the two sets. Recall that the distance from the tip of the whisker to the edge of the boxplot represents 25% of the data exactly. The same can be said if you went from the edge of a box (either Q1 or Q3) to the median.
