Step-by-step explanation:
blocking is not used in this experiment
Answer: A.
The system is consistent because the rightmost column of the augmented matrix is not a pivot column.
Explanation: a system is consistent if and only if the rightmost column of the augmented matrix is not a pivot column. Since every column of the coefficient matrix is a pivot column, none of the leading coefficients are in the rightmost column of the augmented matrix. Therefore the rightmost column of the augmented matrix cannot be a pivot column and the system must be consistent.
Best estimate of the area of a triangle = 100
.
Solution:
Given base of the triangle = 23.62 cm
Height of the triangle = 8.33 cm
Area of the triangle = 


Area of the triangle = 98.3773 
Estimation means rounded off to the closest correct answer.
98.3773 rounded off to 100.
Hence, best estimate of the area of a triangle = 100
