A liquid substance was left at the scene of the crime. Krisann uses a beaker that measures to the nearest tenth of a liter and f
inds that it is 4.9
liters. If there are five or more liters of the substance, it needs to be sent to the lab for testing. If it is less than five liters, the test can be done immediately. Does Krisann need to send the substance to the lab? Why or why not?
Select the correct response with the best explanation.
A No since the beaker measures to the nearest tenth of a lier, the actual value of the measurement is 4.9 liters.
B yes, since the beaker meaures to the nearest tenth of a liter , the range of the actual value is plus or minus 0.1 liters , which means there could be up to 5 liters of the substance
c. Yes, since the beaker measures to the nearest tenth of a liter, the range of the actual value is plus or minus 0.5 liters, which means there could be up to 5.4 liters of the substance
D No, since the beaker meausures to the nearest tenth of the liter , the range of the actual value is plus or minus 0.05 liters , which means there could be up to only 4.95 liters of the substance.
4.85
<= x < 4.95 . does not intersect x > 5.No it
does not need to be sent to the lab. B. <span>yes,
since the beaker meaures to the nearest tenth of a liter , the range of
the actual value is plus or minus 0.1 liters , which means there could
be up to 5 liters of the substance </span>
