In solving the volume of a square pyramid the following formula is to be used:
V = a² h/3
where;
a = base edge
h = height
Thus, the V ≈ 2.53 × 10⁵. Computed in another way:
V = (54)² × (260/3)
= 2916 × 86.67
= 252,729.72
≈ 2.53 × 10⁵
The given equation is the best line that approximates the linear
relationship between the midterm score and the score in the final exam.
- AJ's residual is 0.3, which is not among the given options, therefore, the correct option is. <u>E. None of these</u>.
Reasons:
The given linear regression line equation is;
= 25.5 + 0.82·![\mathbf{\hat x}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Chat%20x%7D)
Where;
= Final exam score;
= The midterm score;
AJ score in the first test,
= 90
AJ's actual score in the exam = 99
Required:
The value of AJ's residual
Solution:
By using the regression line equation, we have;
The predicted exam score,
= 25.5 + 0.82 × 90 = 99.3
- The residual score = Predicted score - Actual score
∴ AJ's residual = 99.3 - 99 = 0.3
AJ's residual = 0.3
Therefore, the correct option is option E;
