Answer:
i think it is 6 but not sure
Step-by-step explanation:
<span>The distance from the vertex to the centroid is twice the distance from the centroid to the side.
This means that 3x + 5 = 2 * (2x)
</span><span>3x + 5 = 4x
x = 5

If the E(X) = 1 then that means it has a 100% which is incorrect.
Each
block has an equal probability to contain the error so 1/3 because you
choose 2/6.
[(21 + 6) − 3^2] ÷ 9 ⋅ 2=[(27) − 9] ÷ 9 ⋅ 2
=18 ÷ 9 ⋅ 2
= 2 . 2
= 4
