Use the probability distribution for the random variable x to answer the question. x 0 1 2 3 4 p(x) 0.12 0.2 0.2 0.36 0.12 Calculate the population mean, variance, and standard deviation. (Round your standard deviation to three decimal places.)

--- Mean

-- Variance

--- Standard deviation

Step-by-step explanation:

Given

Solving (a): The population mean

This is calculated as:

So, we have:

Solving (b): The population variance

First, calculate:

using:

So, we have:

So, the population variance is:

Solving (c): The population standard deviation

This is calculated as:

congruent segments

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
