Answer:
A and C
Step-by-step explanation:
If a data set contains three points, and two of the residuals are -10 and 20, the third residual is 10 (option B).
<h3>What is a residual?</h3>
A residual is the difference between the observed value and the estimated value of the quantity of interest.
The residual of a data points should normally sum up to zero (0). This means the following applies:
-10 + 20 + x = 0
x = 10
Therefore, if data set contains three points, and two of the residuals are -10 and 20, the third residual is 10.
