Option B.

Step-by-step explanation:

A quality control manager is inspecting four digital scales to see if they accurately reflect a weight of 0 ounces.

The given data table is

Empty Scale          Weight Displays Scale

     1                                   –1 ounce

     2                                  –2 ounces

     3                                    0 ounces

     4                                   –1 ounce

It means the errors of the four scales are -1,-2,0 and -1 respectively.

Formula for average:

The average error in the scale displays is

The average error in the scale displays is -1 ounces. Therefore, the correct option is B.

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
