The dot plots below show the heights of some sixth graders and seventh graders. The mean absolute deviation MAD for the first look at is 1.2 in the MAD for the second set of data is 1.7 approximately how many times the variability in the heights of the six graders is the variability in the heights of the seventh graders around all values to the 10th place.
1.2 1.4 2.4 2.8 PLEASE HURRY I HAVE 10 minutes

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
