The table below represents the volume of a liquid sample as a function of its temperature:

The average rate of change of f(x) between x = 11 to x = 21 is
ml per °C and
represents the rate of change of volume per degree rise in temperature.

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

two data sets with the same median will not have the same varaibility
