Okay, between the question & the other answer, I'm quite unsure what discombobulates me the most -_-"
The lower bound of 7000 rounded to one significant figure is 6500. This is because when rounding to one significant figure, we consider the first non-zero digit (7 in this case) and round down to the nearest value that retains the same order of magnitude. Therefore, the lower bound is 6500, while the upper bound would be 7500.
9.685 to 9.694
It is 5400.
They’re the ‘real value’ of a rounded number. Upper and Lower Bounds are concerned with accuracy. Any measurement must be given to a degree of accuracy, e.g. 'to 1 d.p.', or ' 2 s.f.', etc. Once you know the degree to which a measurement has been rounded, you can then find the Upper and Lower Bounds of that measurement. Phrases such as the 'least Upper Bound' and the 'greatest Lower Bound' can be a bit confusing, so remember them like this: the Upper Bound is the biggest possible value the measurement could have been before it was rounded down; while the Lower Bound is the smallest possible value the measurement could have been before it was rounded up.
How do you calculate the upper and lower bounds? Image result for How to find the upper and lower bound of 1000? In order to find the upper and lower bounds of a rounded number: Identify the place value of the degree of accuracy stated. Divide this place value by
Lower and Upper bound of 1000 of two significant figures is 100Plus or minus 50 is 950 , 1050
Lower bound is 17.6 and upper bound is 17.8
Given a value for some variable, it is the maximum value that it could have had wich would have been rounded to the given value.
A function whose upper bound would have attained its upper limit at a bound. For example, f(x) = x - a whose domain is a < x < b The upper bound is upper bound is b - a but, because x < b, the bound is never actually attained.
The answer is B.
An upper bound estimate is a estimate that is greater than the actual solution.
