The dot plots below show the scores for a group of students for two rounds of a quiz: Two dot plots are shown one below the other. The title for the dot plot on the top is Round 1 and the title for the bottom plot is Round 2. Below the line for each dot plot is written Score. There are markings from 1 to 5 on the line at intervals of one. There are there are 6 dots above the mark 4 and there are 2 dots above the mark 5.For the bottom dot plot there are there are 4 dots above the mark 4 and there are 4 dots above the mark 5. Which of the following inferences can be made using the dot plots? There is no overlap between the data. The range of each round is the same. Round 1 scores are higher than round 2 scores. Round 2 scores are lower than round 1 scores.

I believe it is B, the ranges are the same.

Step-by-step explanation:

The first one adds up to 34 while the second adds up to 36.  This puts C and D to false.  I did the test myself and A was incorrect.  Plus, 34 and 36 are very close, so their range must be the same.  Sorry if incorrect e.e

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
