The two dot plots below show the heights of some sixth graders and some seventh graders. the mean absolute deviation (mad) for the first set of data is 1.2 and the mad for the second set of data is 0.6. approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? answers: .3 1.2 1.7 2.0 show how you derived at the answer. you

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

probably the last option
