Amy:
8 + 5 + 6 + 11 + 4 + 6 +8 = 48
48 divide by 7 = 6.85
chelsea:
7 + 9 + 5 + 3 + 10 + 5 + 8 = 47
47 divide by 7 = 6.71
amy runs more on average.

A consistent and independent system of equations describes the given system of equations.
The consistent and independent system of equations are given below.
- 12x+5y-3z= 36
- x-2y+4z=3
- 9x-10y+5z = 27
<h3>What is a consistent independent equation?</h3>
A consistent equation is a system of linear equations that is consistently unbiased when it has precisely one solution. While this is the case, the graphs of the lines within the system move at exactly one point. In inconsistent, a system of linear equations is inconsistent if it has no solutions.

Answer:
Step-by-step explanation:
The application of probability distribution function is employed in solving the question. The detailed analysis and step by step approach is as shown in the attached file.
Using the given linear function, the formula underestimates the median weekly earnings in 2013 by $3.
<h3>What is the linear function for the estimate?</h3>
The function that estimates the median weekly earnings n years after 1980 is given by:
W = 13n + 231.
2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by:
W = 13 x 33 + 231 = 660.
Since 657 < 660, the formula underestimates the median weekly earnings in 2013 by $3.
