Fiona recorded the number of miles she biked each day last week as shown below. 4, 7, 4, 10, 5 the mean is given by m = 6. which equation shows the variance for the number of miles fiona biked last week?

Given that the mean of the equation is given by:
m=6
the variance is given by the formula:
[∑(x-m)²]/(n-1)
∑(x-m)²=[(4-6)²+(7-6)²+(4-6)²+(10-6)²+(5-6)²]=26
hence the expression will be:
26/(n-1)
where n=5, the number of times she ran
