A number x is rounded to 1 decimal place and its 3.7
write down the error interval for x

i think it's because i worked it out

The error interval for x is:

                 [3.65,3.74]

A number, x, rounded to 1 decimal place is 3.7. Write down the error interval for x. The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 21⋅0.

Step-by-step explanation:

The number after rounding off is obtained as:

                         3.7

We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:

  3.65     3.66    3.67    3.68    3.69    3.70    3.71   3.72    3.73    3.74

( Because if we have to round off a number present in decimals to n place then if  there is a  number greater than or equal to 5 at n+1 place then it will result to the one higher digit  at nth place on rounding off and won't change the digit if it less than 5 )

        So , the error interval is:

            [3.65,3.74]
