The
mean absolute deviation will show us on average how far each of all
the data points from the graph that Makayla collected are from the
mean. To calculate it you simply have to use the formula shown in the
attachment. It is very easy but will take you like 5 minutes to
solve. Use it for each data set.

Answer:
x=2 and y=36
Step-by-step explanation:
you have two equations
1) xy=72 and 2) (x+2)(y-4)=128
solve for one of the variables in equation 2), lets do y
(x+2)(y-4)=128, divide by (x+2) to both sides and add 4 to isolate variable y
therefore, y=(128/(x+2))+4
then plug in y into equation 1)
so x(our new y)=72
x( 128/(x+2) +4 )=72
distribute the x so you will get
(128/(x+2))x +4x=72
we are now solving for x, so isolate the x by subtracting 4x and multiplying by (x+2) to get
128x=(x+2)(72-4x)
multiply by distribution and combine like terms
-4x^2 -64x +144 =0
solve for x by quadratic formula, you'll get x=2 or x=-18
substitute back into equation 1), (2)(y)=72, solve for y to get 36
then you can check by substituting back into equation 2)
(2+2)(36-4)=128
(4)(32)=128, 128=128
Answer:
-8
Step-by-step explanation:
2x + 9 = -7
Subtract 9 from both sides
2x = -16
Divide both sides by 2
x = -8
The value of p is going to be 4
