Bananas are $0.59/pounds. what is the constant of proportionality?

For this case, the first thing we must do is define variables.

We have then:

x: amount of weight in pounds

y: total cost of bananas.

The equation that models the problem is:

We observe that the relationship is linear. Therefore, the variables are proportional.

The proportionality constant is:

the constant of proportionality is:

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.
