Answer:
1/2
Step-by-step explanation:
Take any point from the original, like (2,2) If the new point is (1,1) then the change would be 1/2
Answer:
3
Step-by-step explanation:
The x-coordinate of the accident is a random variable of uniform distribution with range [-1.5,1.5]. The same can be said for the y-coordinate. However, |x| and |y| are also uniform variables with range [0,1.5], since we still have the same probability on every pair of intervals with the same lenght.
Note that |X| and |Y| are independent with each other, therefore E(|x|+|y|) = E(|x|) + E(|y|) = 2*E(|x|). The last equality holds because both x and y are identically distributed, then so are |x| and |y|.
E(|x|) = 
Therefore, E(|x| + |y|) = 2 * 3/2 = 3.
I hope that works for you!

Answer:

Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (4, 8)
m =
= 
Note the line crosses the y- axis at (0, 5) ⇒ c = 5
y =
x + 5 ← equation in slope- intercept form
