Answer:

The expected value of the distribution is 0.9

Step-by-step explanation:

We are given the following probability distribution in the question:

x:               0             1                2

P(x):       0.45        0.20         0.35

We have to find the expected value of the given distribution.

The expected value of the distribution is the mean of the distribution.

Formula:

E(x) = \displaystyle\sum x_iP(x_i)\\\\\text{Puttinf the values, we get,}\\E(x) = 0(0.45) + 1(0.20) + 2(0.35)\\E(x) = 0.9

Thus, the expected value of the distribution is 0.9

What’s the surface area
STALIN [3.7K]

Answer: 38 in.^{2}


Step-by-step explanation:

1/ Find the area of the triangular sides. (1/2 x 2 x 6 = 6 in.^{2} for each triangular side)

2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = 12 in^{2}. The rectangular side on the left is 2x3 = 6 in.^{2}, and the rectangular side on the right is 4x2 = 8 in.^{2}.

3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> 12 in.^{2} + 6 in.^{2} + 8 in.^{2} + 6 in.^{2} + 6 in.^{2} = 38 in.^{2}

4/ You have your answer, now hope it helps ! :)
