Question

What is a bound in maths I am confused in class?

Answer 1

Step-by-step explanation:

Upper bound: a value that is greater than or equal to every element of a set of data. Example: in {3,5,11,20,22} 3 is a lower bound, and 22 is an upper bound. But be careful! 2 is also a lower bound (it is less than any element of that set), in fact any value 3 or less is a lower bound.

Answer 2

Answer:

The lower bound is the smallest value that would round up to the estimated value. The upper bound is the smallest value that would round up to the next estimated value. For example, a mass of 70 kg, rounded to the nearest 10 kg, has a lower bound of 65 kg, because 65 kg is the smallest mass that rounds to 70 kg.
