Find the distance between the two points rounding to the nearest tenth (if necessary) (8,7) and (1,-2)

≈ 11.4

Step-by-step explanation:

Calculate the distance using the distance formula

d =

with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)

d =

   =

   =

   =

   ≈ 11.4 ( to the nearest tenth )

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
