I took the quiz so...

Answer 2

Find out the percent error in Annie's estimate .

To prove

Formula

`Percentage\ error = (error* 100)/(exact\ value)`

As error = approx value - exact value

As given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

approx value = 78.25 in.

actual value = 75.50 in.

error = 78 .25 - 75 .50

= 2.75

put in the formula

`Percentage\ error = (2.75* 100)/(75.50)`

`Percentage\ error = (27500)/(7550)`

Percentage error = 3.64 % (approx)

Therefore the Percentage error be 3.64 % (approx).
