Cynthia rounds a number x to one decimal place the result is 6.3 write down the error interval for x

6.25 ≤ x ≤6.34

Step-by-step explanation:

Given that:

Number, x rounded to 1 decimal place = 6.3

The lowest value number x could be is ;

6.25, rounding 6.25 to 1 decimal place = 6.3

The highest value number x could be is ;

6.34, rounding 6.34 to 1 decimal place = 6.3

Hence, the error interval for X is

Lowest possible value ≤ x ≤ highest possible value

6.25 ≤ x ≤6.34
