What is the constant of proportionality of y=6.78x

k = 6.78

Step-by-step explanation:

If two variables x and y are respectively the independent and dependent variables and they are proportional to each other, then we can write the mathematical expression as y ∝ x.

This gives, y = kx (1)

Where k = proportionality constant.

Now, we are given a linear equation of x and y and we have to get the constant of proportionality.

The given equation is y = 6.78x (2)

Now, comparing equation (1) and (2) we get k = 6.78. (Answer)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
