Answer:
42.1558 km
Step-by-step explanation:
We know that 1 mile = 1,609 km
Then use this data as a conversion factor.
If we want to transform miles to kilometers then our conversion factor should be:

Now we must multiply the number of miles by this factori and thus we obtain the equivalent in kilometers

All real numbers except 0
I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
To find the variance, you must square the standard deviation, or <span>σ.
</span>
<span>σ = 23.9
The variance is
</span>
<span>σ²= 23.9² = 571.21
