for example you use a beam balance to find the mass of a rock sample for a science lab. you read the scale as 3.8g. what is your greatest possible error?
well the rocks mass was measured to the nearest 0.1g, so the greatest possible error is one half of 0.1g
he's right but here's the definition: one half of the unit of measurement to which the measure is being rounded. EX. the greatest possible answer of 3g is 1.5g
If you have 3 cm, you are measuring to the nearest cm, so the greatest possibel error would be .5 cm.
first you must find the precision. that is the smallest possible unit of the smallest measurement. in this case the smallest measurement is 5/10ths. the smallest possible unit is 1/10. so 1/10 is the precision. to find the greatest possible error you have to multiply the precision (1/10) by 1/2. and you get 1/20. the greatest possible error is 1/20. another example: find the greatest possible error of both 6 and 3.214. for 6 the smallest unit would be 1 because you can go lower than one without going to the next unit down. so we then take one and multiply it by 1/2. one half is also 0.5. 1 multiplied by 1/2 is 1/2, therefore, the greatest possible error of 6 is 1/2 or 0.5. for the next number take the smallest unit of 214/1000, which is what .214 is. the smallest measurement would be 1/1000. that is our precision. the greatest possible error is one half (1/2) of the precision, or, 1/1000 x 1/2, which equals 1/2000. the greatest possible error of 3.214 is 1/2000. it's kind of confusing. i hope this helped. first it helps to understand the precision. then from there the gpe is half of the precision.
An eighth of an inch.
The greatest possible error for a measurement is typically half of the smallest unit of measurement. In this case, the smallest unit of measurement is 1 foot, so the greatest possible error for a 14-foot measurement would be 0.5 feet. This means that the actual measurement could be as low as 13.5 feet or as high as 14.5 feet.
The greatest possible number is 888... (repeating).
Add the two greatest possible four digit numbers. 9999 + 9999
what is the greatest possible error of 350mi
The greatest possible error is 0.005
0.5
0.5
The greatest possible error is 0.0005
bich find it cho self
Assuming that the measurement is to the nearest 0.01, the greatest possible error is 0.005.
If the numbers are rounded to the nearest 750, then 375 is the greatest possible error. Although you are not likely to have counted in 750s, it is quite possible that you counted in 50s (greatest error = 25). Or in tens (GE = 5) or in units (ones), when the greatest error is 0.5. The greatest possible error is half of the smallest unit of measurement.
.5cm/.5cm/.005g
Assuming the number is written to its greatest precision, it will be half of the place of the last digit. Since the 9 is in the tenths place, the greatest possible error is ±0.5*a tenth = ±0.05 metres.
The greatest possible error for the measurement 0.991 g would be half of the smallest measurable unit, which is typically 0.001 g for this measurement. Therefore, the greatest possible error would be ±0.0005 g.
