Answer:

mean absolute deviation is 8

Step-by-step explanation:

to find mean absolute deviation, you subtract your mean from each of your values, and make them all positive, (even if u get a negative..)

then you add all your new answers up and divide by how many numbers there are (basically just find mean of your new set of data...)

Hope this helps you in the future!!

Which equation is y= 2x ^2 - 8x +9 rewritten in vertex form.

tankabanditka [31]

y= 2x ^2 - 8x +9

y = a(x - h)2 + k, where (h, k) is the vertex of the parabola
so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------vertex form
