See explanation

Step-by-step explanation:

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

$\bar x = \frac{\sum x}{n}$

Assume the data is:

$1287\ 1215\ 1221\ 1229$

This means that the number of schools is 4

So:

$\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}$

$\bar x = \frac{4952}{4}$

$\bar x = 1238$

<em>The average of the assumed data is 1238</em>

In a race 24 out of 25 cyclists finished in less than 51 minutes what percentage of cyclists finished the race in less then 51 m

Gekata [30.6K]

Answer: 96%

Step-by-step explanation:

There are 25 total cyclists and 24 of those finished the race in less than 51 minutes. The question would like this 24 to be expressed as a percentage of 25.

In percentage this would be:

= Number of cyclists who finished in 51 minutes / Total number of cyclists * 100%

= 24 / 25 * 100%

= 96%
