Question

A baby is weighed on a defective scale. He weighed 28 pounds according to the scale. He weighs 25 pounds on an effective scale. What is the percent error?

Answer 1

Answer:

10.7%

Step-by-step explanation:

Step one:

given

expected  weight= 28pounds

Actual weight= 25 pound

Required:

percent error

$\delta = \left| \frac{v_A - v_E}{v_E} \right| \cdot 100\%$

δ= percent error

vA =actual value observed

vE =expected value

δ=25-28/28*100

δ=-3/28*100

δ=0.107*100

δ=10.7%

The percent error is 10.7%
