The correct answer is choice C. The mean absolute deviation is a way to show the variability, or how spreadout the data is. When the mean absolute deviations are close to each other, that tells us that they're comparable in how they vary. 6.9 is close to 7.1.
Make an equation in point-slope form, which is y - y = m(x - x)
First find the slope. The formula for slope is (y - y) over (x - x). In this case, the slope is (9 - 5) over (6 - 2) which simplifies to 1. The slope will be m in the point-slope equation.
Now fill in the formula:
9 - 5 = 1 (6-2)
This is the answer.
Answer:
B. is dependent
Step-by-step explanation:
The denominator determinant will be zero when the coefficients of the variables are dependent. One of the numerator coefficients will be zero when the coefficients involved are dependent. Hence using Cramer's Rule will result in the ratio 0/0 when the system is dependent.
___
The ratio will be 1/0 if the system is inconsistent (has no solution).
