"Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data. The four main ways to describe variability in a data set are:
<span>Range Interquartile range Variance Standard deviation.
it is hard to explain but i hope this helped:/:)</span>
1 meter=100cm=1000mm=0.1km
2meter=200cm=2000mm=0.2km
answer is D
This is my thinking;
To convert meters to kilometers, in decimals, its 0.001. So converting that into kilometers, that would be 0.057
So first divide 420 by 3 which gets you 140 so now you need to divide that 140 by 20 which is 7 so the jeweler could make 7 necklaces which is B. If you have any questions just ask. Hope I helped you ❤️
