Question

Sally estimated that her call would take minutes but it actually took minutes. What was her percent of error?

Answer 1

You're missing the #'s

Answer 2

12 minutes . and 10 *

Answer 3

Firsrtly, find the error. So, the difference between her guess and the actual answer.

Secondly, find the percentage.

In this case, 12-10=2. So the error is 2.

You will use the error divided by the actual answer x100 to find the percent error.

Answer 4

so 2 times 100 ?

Answer 5

which is 200 ?

Answer 6

No no, firstly, take the error and divide it by the actual answer -then- multiply by 100. So, (2/10)=.2 and then .2 x 100

Answer 7

so 20 percent ? thanks !
