Final answer:(option E). 1The correlation between the actual masses and the respective masses displayed by the scale is 1 (option E), with a constant difference of 0.75 kilograms.Explanation:Thecorrelationbetween the actual masses of a set of objects and the respective masses displayed by the scale is 1 (option E).Let's say the actual mass of an object is m kilograms. According to the scale, the displayed mass would be m - 0.75 kilograms. So, the difference between the actual mass and the displayed mass is m - (m - 0.75) = 0.75 kilograms. This implies that the actual masses and the displayed masses have a correlation of 1, meaning they have a constant difference of 0.75 kilograms.For example, if the actual mass of an object is 2 kilograms, the displayed mass on the scale would be 2 - 0.75 = 1.25 kilograms.Learn more about correlation here:brainly.com/question/36761554#SPJ11...
