Two hundred and eighty boys completed a test that measures the distance that the subject can walk on a flat, hard surface in 6 minutes. For each age group shown in the table, the median distance walked by the boys in that age group is also given. Age Group Representative Age (Midpoint of Age Group) Median Six-Minute Walk Distance (meters) 3β5 4 544.3 6β8 7 584.0 9β11 10 667.3 12β15 13.5 701.1 16β18 17 727.6 This experiment also reported the 6-minute walk distances (in meters) for 248 girls age 3 to 18 years. The median 6-minute walk distances for girls for the five age groups, respectively, were 490.4 576.3 655.8 655.6 658.9. (a) With x = representative age and y = median distance walked in 6 minutes, construct a scatterplot for the girls' distances. A scatterplot has 5 points. The horizontal axis is labeled "x" and ranges from 0 to 20. The vertical axis is labeled "y" and ranges from 460 to 700. The first 2 points are plotted from left to right with little vertical change starting from the upper left of the diagram. The next 3 points continue to the right in a downward, diagonal direction. The points are plotted with very little scatter. A scatterplot has 5 points. The horizontal axis is labeled "x" and ranges from 0 to 20. The vertical axis is labeled "y" and ranges from 460 to 700.

1) your friend taylor missed class today and needs some identifying solutions of systems. explain to taylor where to find the solution(s) of any system using its graph 2)taylor graphs the following in desmos and decides that f(x) = g(x) at x = 0, x = 1, & x = 3. f(x) = 2x+1g(x) = 2x2+1 provide taylor some feedback that explains which part of the answer was incorrect and why.
