Answer:
The answer is below
Explanation:
Probability distribution are statistical function that shows all the possible outcomes of a random variable within a given range of values.
a) The mean (
) of a probability distribution of a discrete random variable is:
![\bar x=\Sigma\ [xP(x)]](https://tex.z-dn.net/?f=%5Cbar%20x%3D%5CSigma%5C%20%5BxP%28x%29%5D)
= (0 * 0.8) + (1 * 0.15) + (2 * 0.04) + (3 * 0.01) = 0.26
b) The standard deviation (σ) of a probability distribution of a discrete random variable is:
![\sigma=\sqrt{ \Sigma\ [(x-\bar x)^2*P(x)]}\\\\\sigma=\sqrt{(0-0.26)^2*0.8+(1-0.26)^2*0.15+(2-0.26)^2*0.04+(3-0.26)^2*0.01} \\\\\sigma=0.577](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7B%20%5CSigma%5C%20%5B%28x-%5Cbar%20x%29%5E2%2AP%28x%29%5D%7D%5C%5C%5C%5C%5Csigma%3D%5Csqrt%7B%280-0.26%29%5E2%2A0.8%2B%281-0.26%29%5E2%2A0.15%2B%282-0.26%29%5E2%2A0.04%2B%283-0.26%29%5E2%2A0.01%7D%20%5C%5C%5C%5C%5Csigma%3D0.577)
Answer:
False
Explanation:
Both supply and demand concepts rest on the relationship between price and quantity.
Quantity demanded increase when price falls and falls when price increases.
Quantity supplied increases when price increases and falls when price falls.
The demand and supply curve are plotted with price on the y axis and quantity on the x axis.

Answer:
Bad Debt Expense ($40,000 - $3,200) $36,800
To Allowance for Doubtful Accounts $36,800
(Being the bad debt expense is recorded)
Explanation:
The adjusting entry is shown below:
Bad Debt Expense ($40,000 - $3,200) $36,800
To Allowance for Doubtful Accounts $36,800
(Being the bad debt expense is recorded)
For recording this we debited the bad debt expense as it increased the expenses and credited the allowance for doubtful debts as it decreased the value of the assets
And since there is a credit balance so the same is deducted from the account receivable
Answer:
Option c. 5.25 times is the correct answer.
Explanation:
Below is the calculation:
Income before income tax = $420000
Income tax expenses = 120000 dollars
Net income = $300000
Interest expense = $80000
Interest earned ratio = Earning Before Interest and Taxes / Interest Expenses
Interest earned ratio = 420000 / 80000
Interest earned ratio = 5.25 times
Option c. 5.25 times is the correct answer.
