The lower quartile is the mean of the lower half of the data set, not incuding the median value. In this case, the lower half is 5, 8, 10, 20 and the median is 9.
On the augmented matrix, each row represents an equation of the linear system. From left to right, the first three elements of the row represent the coefficients of the variables in order, the last element represent the right side of the equation.
On the third row we have the elements 3 8 0 4, which gives to us the following equation

Answer:
12
Step-by-step explanation:
if the perimeter is 54, and the length is 15,
first double the length (to include both sides of the rectangle):
15(2)=30
subtract that by 54:
54-30=24
to find the width we would divide 24 by 2, because 24 represents both sides of the rectangle:
24/2=12
the width is 12.
