Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.
tankabanditka [31]

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 % .
