Amanda measures the top of an 80 cm desk to be 82.4 cm. dwayne measures the height of a 140 cm cabinet to be 137.2 cm. which student has a greater percent error? explain your reasoning.

Percent error is given by formula

Error calculation for Amanda:

Accurate measurement value of the top of desk = 80 cm

Measured value by Amanda = 82.4

Error = 82.4-82 = 2.4

Now plug these values to find the percent error.

----

Error calculation for Dwayne:

Accurate measurement value of the cabinet = 137.2 cm

Measured value by Dwayne = 140

Error = 140-137.2= 2.8

Now plug these values to find the percent error.

3% is clearly more than 2%.

Hence final answer will be:

Amanda has greater percent error than Dwayne.

no not all of them.
