Question

The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners. At most, what is the percent error?

Answer 1

25% is the percent error.

Explanation:

Given:

The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

Now, to find the percent error.

As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

The actual measure = 2 million.

The estimated measure = 2.5 million.

So, the error =
`2.5-2=0.5\ million.`

Now, to get the percent error:

`(0.5)/(2) * 100.`

`=0.25* 100`

`=25\%.`

Therefore, 25% is the percent error.
