Answer:
The percentage error is 3.6 % .
Step-by-step explanation:
Formula
[tex]Error\ percentage = \frac{Error\times 100}{Exact\ value}[/tex]
[tex]Error = \left |Approx - Exact \right |[/tex]
As given
Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.
Here
Approx value = 78.25 in
Exact value = 75.50 in
[tex]Error = \left |78.25 - 75.50\right |[/tex]
Error = 2.75
Put in the formula
[tex]Error\ percentage = \frac{2.75\times 100}{75.50}[/tex]
[tex]Error\ percentage = \frac{275}{75.50}[/tex]
Error percentage = 3.6 %
Therefore the percentage error is 3.6 % .
