Question

A factory tries to make a 6 mm screw. It ends up being5.7 mm instead.One way to describe the error is 0.3 mm.Another way is to describe it as a PERCENT ERROR.This screw has a percent error of0.3/6= 5%.Complete the table to decide if each screw will work inits bookcase (its percent error must be 10% or less).

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

Table

screw percent error = ?

error bookcase 10% or less :

will it work = ?

Step 02:

percent error = |(desided width - screw width)| / desided with * 100

screw 2:

percent error = |( 10 - 10.9)| / 10 * 100% = 9%

It will work.

screw 3:

percent error = |( 6 - 7.2)| / 6 * 100% = 20%

It will not work.

screw 4:

percent error = |( 15 - 13.8)| / 15 * 100% = 8%

It will work.

The answer is:

screw 2:

percent error = 9%

it will work

screw 3:

percent error = 20%

it will not work

screw 4:

percent error = 8%

it will work
