Question

A students calculation was found to have a 35.5% error, and his experimental measurement was 15.6 cm. What are the two possible values for the actual measurement?

Answer 1

Two possible measurement will be 21.138 cm and 10.062 cm

Explanation:

We have given that error in calculation is 35.5 %

And it is given that experimental experiment measure is 15.6 cm

We have to find the two possible values of actual measurement

The two possible value of actual measurement will be

`15.6+(15.6* 35.5)/(100)` and
`15.6-(15.6* 35.5)/(100)`

Which are equal to

`15.6+(15.6* 35.5)/(100)=15.6+5.538=21.138cm`

And
`15.6-(15.6* 35.5)/(100)=15.6-5.538=10.062cm`
