Students were asked how many pairs of shoes they owned. their responses were 8, 2, 1, 5, 7, 6, 2, 2, 8, and 3. the mean of the data is

4.4

Step-by-step explanation:

The mean is the sum of the data divided by the number of data values.  so add them all together and then divide by how many numbers you added together.

Here is an example 1,3,4,5,7 so add 1+3+4+5+7=20 then you divide 20 by 5 and the mean is 4 for this example.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

i think it is c, not positive though
