Use the data set to answer questions 1-3. 25, 8, 10, 35, 5, 45, 40, 30, 20
What is the upper quartile of the given data set?
A. 35
B. 37.5
C. 37
D. 40

Q3 = 37.5

Step-by-step explanation:

Place the data items in order from least to greatest

5, 8, 10, 20, 25, 30, 35, 40, 45

Find the number in the middle 25

Then take the number on the right, take the two numbers in the very middle add them together and divide by 2. 35+40 = 75/2 =37.5

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

maybe showing the graph would
