25,8,10,35,5,45,40,30,20
what is the upper quartile of the data set above?
a.35
b.37.5
c.37
d.40

1. Median of the data set is 25. Therefore the correct option is C.

2. The upper quartile of the data set is 37.5. Therefore the correct option is B.

Step-by-step explanation:

The given data set is

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

Arrange the data in ascending order.

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

Median of the data set divides the data into two equal parts. Median is the middle term of the data set.

Divide the data in two equal parts.

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

Median of the data set is 25. Therefore the correct option is C.

Divide each parenthesis in two equal parts.

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

Upper quartile of the data set divides the data in 3:1.

The upper quartile of the data set is 37.5. Therefore the correct option is B.

your answer would be b

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
