1. A student measures the height of a small lamp to be 32cm. According to the factory specifications,
the lamp is actually 30cm. What is the percent error of the student's measurement?

Respuesta :

Answer:

6.67 %

Explanation:

Given that,

Measured height of a small lamp, l = 32 cm

Actual height, l' = 30 cm

We need to find the percent error of the student's measurement. Percent error is given by :

[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]

Putting all the values, we get :

[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]

So, the percent error of the student's measurement is 6.67 %.
