9514 1404 393

  no

Step-by-step explanation:

It is impossible to plot an equilateral triangle on a coordinate grid using integer coordinates. The given triangle may be close, but cannot be an equilateral triangle.

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
