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.

The expression: Can you explain how to factor out the 1/3 from 2 in detail I am having trouble.

Answer:

Explanation:

If you multiply (x - k)(x + k), you get $x^{2} + k*x - k*x - k^{2}$ which is equal to $x^{2} -k^{2}$ . Now you can see that $\frac{1}{3} *x^{2} - 2$ must be equal to $\frac{1}{3}*(x^{2} - k^{2})$ which is equal to $\frac{1}{3}*x^{2} - \frac{1}{3}*k^{2}$ . Now we just need to solve $2 = \frac{1}{3}*k^{2}$ . The final answer is $k = +- \sqrt{6}$ .
