Arianna recorded data on the amount of rainfall (in mm) during a given week and the depth (in m) of water in the local creek (stream) at the end of the week, as shown in the plot. Notice that r2 = 0.99 and the equation of the line of best fit is y = 0.483x + 0.067 5- a) What is the value of r (rounded to three O decimal places)? Describe the type and strength of the correlation. 3- Depth_m 2. 2 6 8 10 12 Rainfall_mm -Depth_m = 0.483Rainfall_mm + 0.067; r2 = 0.99 b) The creek (stream) will overflow and cause flooding if the depth exceeds 5.5 m. What amount of rainfall (rounded to one decimal place) will result in a flood warning
