Upper bound =



Answer :

The lower bound is 88mm and upper bound is 230 mm

What is range?

The range is the range of values, from lowest to highest.

When there are numbers that are wildly high or low, the range can occasionally be deceptive.

Example: In {8, 11, 5, 9, 7, 6, 3616}:

the lowest value is 5,

and the highest is 3616,

So the range is 3616 − 5 = 3611.

The single value of 3616 makes the range large, but most values are around 10.

Length of Ribbon = 23 cm = 230 mm

If she cuts off the ribbon = 87 mm

Then the remaining ribbon is

=230- 87

= 143mm

So, lower bound is 88mm and upper bound is 230 mm

Hence, the range is 88mm - 230 mm.
