Suppose a certain scale is not calibrated correctly, and as a result, the mass of any object is displayed as 0. 75 kilogram less
r-ruslan [8.4K]

The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1

<h3>What is the Correct Scale Calibration?</h3>

We are told that a certain scale is not calibrated correctly,

Mass displayed = 0.75 kg (less than its actual mass).

The scale of display = 1

Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.

Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.

ASHA 777 [7]

The repetition of the phrase "do i dare?" three times indicates that: he is indecisive.

One of the central themes that were explored in "The Love Song of J. Alfred Prufrock" is the social anxiety that he experiences.

He is worried about people's conception of him and that is why before he descends the stairs, he wonders if he can dare face the people because of the bald spot in the middle of his head and several other insecurities.

So, option A is correct.
