Your realized income is $2,943.20 /month. How much are your fixed expenses each month? How much could you save per month if you
valkas [14]

Answer:

The saving amount per month is $ 735.8 And

The Expenses amount per month is $2,207.4

Step-by-step explanation:

Given as :

The total per month income = $2,943.20

The saving percentage amount per month = 25% of discretionary money  

So , The saving amount per month = 25 % of $2,943.20

                                                          = .25 × $2,943.20 = $735.8

The amount which is fixed as each month expenses = total monthly income - total monthly saving

So, Expenses amount per month = $2,943.20 - $735.8

                                                       = $2,207.4

Hence The saving amount per month is $ 735.8 And The Expenses amount per month is $2,207.4     Answer

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}
