Paulo uses an instrument called a densitometer to check that he has the correct ink colour.

for this print job the acceptable range for the reading on the densitometer is 1.8 ± 10%.

what is the acceptable range for the densitometer reading?

exactly 1.8

from 0 to 3.6

from 1.0 to 2.6

from 1.62 to 1.98

from 1.8 to 1.98

If it is said that the range of the answer should be +/- 10% of the particular value, we have to find out the percentage of that particular value. Therefore 10% of 1.8 is,

1.8 * 10/100 = 0.18

If we add this value to the original value,
1.8+0.18 = 1.98

If we subtract this value from the original value,
1.8-0.18 = 1.62

therefore the range will be,
from 1.62 to 1.98

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
