The figure below shows the relationship between the
percent of leaf litter mass remaining after
decomposing for 3 years and the mean annual
temperature, in degrees Celsius (°C), in 18 forests in
Canada. A line of best fit is also shown.
Lcaf litter mass
remaining (%)
A particular forest in Canada, whose data is not
included in the figure, had a mean annual
temperature of -2°C. Based on the line of best fit,
which of the following is closest to the predicted
percent of leaf litter mass remaining in this particular
forest after decomposing for 3 years?
A) 50%
B) 63%
C) 70%
D) 82%
Mean annual temperature (°C)

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
