Question

members of a band estimated that 200 people were at their show at night. their manager told them that 227 people had actually been at the show. what was the band's percent error?

Answer 1

\( \text{% error} = \dfrac{|\text{actual - expected}|}{\text{actual}} \times 100\)

Answer 2

How many people actually showed up and how many were estimated/expected to be there?

Answer 3

227 showed up and 200 expected to be there ???

Answer 4

yes, so let's put those numbers into the equation

\( \text{% error} = \dfrac{|\text{227- 200}|}{\text{227}} \times 100\)

227 - 200 = ?

Answer 5

27
??

Answer 6

Good

| | is just absolute value and it's in case we get a number number to make it positive

Now what is 27/227 = ?

Answer 7

227/27 ??

Answer 8

divided

Answer 9

227/27=

Answer 10

oo ok

Answer 11

0.118943

Answer 12

\( \text{% error} = \dfrac{|\text{227- 200}|}{\text{227}} \times 100\)


\( \text{% error} = \dfrac{27}{\text{227}} \times 100\)

We have to simplify the fraction so divide it

Answer 13

That's good! Now multiply it by 100 and that's your % error
