Once you have created both sets of numbers, complete the following tasks. In each task, make sure to clearly label which set you are identifying or describing. Identify the elements of each set that you created. Calculate the mean of each set. Show your work in your answer. Calculate the mean absolute deviation of each set. Show your work in your answer. Describe the process you used to create your sets of numbers under the given conditions.

stops on an even number.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
