Sagot :

to find if it is proportional all the data must fulfill the constant of proportionality.

in this case we can see a pattern in which the yellow flowers tend to be the double of the white flowers.

however this is not fulfilled when there are 7 white flowers, indicating that the arragements are not proportional

[tex]y=kx[/tex][tex]\begin{gathered} 6=k\cdot(3) \\ \frac{6}{3}=k \\ 2=k \end{gathered}[/tex]

the constant of proportionality is 2

[tex]\begin{gathered} 12=k\cdot7 \\ k=\frac{12}{7} \end{gathered}[/tex]
