    Answer:

    The error interval for x is:


                     [3.65,3.74]


    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 )


            Hence, the error interval is:


                [3.65,3.74]
