Answer 2

Answer:

The percentage error is 3.6 % .

Step-by-step explanation:

Formula

$Error\ percentage = \frac{Error\times 100}{Exact\ value}$

$Error = \left |Approx - Exact \right |$

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

$Error = \left |78.25 - 75.50\right |$

Error = 2.75

Put in the formula

$Error\ percentage = \frac{2.75\times 100}{75.50}$

$Error\ percentage = \frac{275}{75.50}$

Error percentage = 3.6 %

Therefore the percentage error is 3.6 % .
