Bounds watch

1. How do you figure the upper and lower bounds of 7.6?
2. Usually there is a unit/significant figure to work by but in this case i'll assume its to 1 d.p
0.1÷2= 0.05
7.6+/- 0.05
7.6 to nearest tenths = 7.55 & 7.65

Moved to the Maths forum
4. they have started calling them "error intervals" for the new exams....

so your error interval would be written as

7.55≤ L <7.65

if the measurement was L for length for instance.
5. thanks

Dat's right!
