The students in ms. lorenzo’s class collected the following numbers of bottle caps:
10, 20, 40, 50, 30, 10, 60, 10, 2040, 30, 30, 50, 70, 50, 70, 60, 30
a. make a dot plot for the data.
b. what is the median?
c. what is the mean?

I am not sure how to show you how to do a dot plot on this website, but to see how to do a dot plot

b) Put everything in order and find the middle
10, 10, 10, 20, 30, 30, 30, 30, 40, 50, 50, 50, 60, 60, 70, 70, 2040
                                             ^^
So 40 is in the middle, making it the median

c) Add all of the values together and divide by the total number of values.
10 + 10 + 10 + 20 + 30 + 30 + 30 + 30 + 40 + 50 + 50 + 50 + 60 + 60 + 70 + 70 + 2040 = 2660
2660 / 17 = 156.5

x=4 so both the answer is 0

Step-by-step explanation:

3x-12=x-4

3x-x=-4+12

2x=8

2x÷2=8÷2

x=4

so

3x-12=4-x

3×4-12=4-4

12-12=4-4

0=0
