We are given the following numbers
[tex]18,28,24,25,15[/tex]We are asked to find the mean of these numbers.
Recall that the mean is given by
[tex]\operatorname{mean}=\frac{sum\text{ }of\text{ }terms}{number\text{ }of\text{ }terms\text{ }}[/tex]For the given case,
sum of terms = 18+28+24+25+15 = 110
number of terms = 5
So the mean is
[tex]\begin{gathered} \operatorname{mean}=\frac{110}{5} \\ \operatorname{mean}=22 \end{gathered}[/tex]Answer:
22
Step-by-step explanation:
We are given a data set:
[tex]18,28,24,25,15[/tex]
We are asked to find the mean of this data set (in other words, find the average).
First, count how many data values there are:
[tex]1. \ 18\\2. \ 28\\3. \ 24\\4. \ 25\\5. \ 15[/tex]
Then, add up the data values:
[tex]18+28+24+25+15=110[/tex]
Then, divide the sum of the data values by the number of data values present:
[tex]\displaystyle \frac{110}{5}=22[/tex]
Therefore, the mean of the data set is 22.
