The probability distribution of a random variable X is given. x 1 2 3 4 P(X = x) 0.4 0.1 0.3 0.2 Compute the mean, variance, and
Readme [11.4K]

Mean:

E(X) = \displaystyle \sum_{x\in\{1,2,3,4\}}x\,P(X=x) = 1\times0.4 + 2\times0.1 + 3\times0.3 + 4\times0.2 = \boxed{2.3}

Variance:

\displaystyle V(X) = E\left((X-E(X))^2\right) = E(X^2) - E(X)^2 \\\\ E(X^2) = \sum_{x\in\{1,2,3,4\}}x^2\,P(X=x) = 1^2\times0.4 + 2^2\times0.1 + 3^2\times0.3 + 4^2\times0.2 = 6.7 \\\\ \implies V(X) = 6.7 - 2.3^2 = \boxed{1.41}

Standard deviation:

\sigma_X = \sqrt{V(X)} = \sqrt{1.41} \approx \boxed{1.19}

Find the area of the figure
zalisa [80]

Answer:

426 cm^2

Step-by-step explanation:

Let, the area of the given figure be A

Let's imagine that the rectangle (at the bottom right) is present.

Then, A = Area of trapezium - Area of rectangle

             = { 1/2 * ( 18 + (20+4) ) * ( 13+9 ) } - ( 4 * 9 )

             = 462 - 36

             = 426

[If there's any mistake, please inform me]
