Answer:
$1,583
Explanation:
Accounts receivables as at 31/12/2021 = $236,000
A/R as at 31/12/2022 :
= Accounts receivables as at 31/12/2021 + increase in AR
= $236,000 + $22,300
= $258,300
Uncollectible accounts = 1% of accounts receivables
= 1% × $258,300
= $2,583
Allowance 31/12/2021 = $8,400
Writes off = $7,400
Therefore,
Allowance = Allowance 31/12/2021 - writes ofd
= $8,400 - $7,400
= $1,000
Hence,
Bad debt expense for 2021 = Uncollectible accounts - Allowance
= $2,583 - $1,000
= $1,583

The formula for annually compounded interest is as follows:

P is the initial amount you invest, r is the interest rate as a decimal, and t is the number of years the money will have been invested.
Convert the 8% interest rate into a decimal by dividing by 100:

We now have all of our values. Plug the known values into the equation:





Answer:
The standard deviation is 0.73 times the value of your investment
Explanation:
Standard deviation is the measure of dispersion from the mean of the group as a whole.
It is a group statistic, so it is necessary to see the project's result as a group result.
Let P be the value of your investment.
If you can invest 100 times in the project then after 1 year you will receive 2P for 60 times and 0.5P for 40 times. The 40% ad 60% information is not conditioned on a sample so the case should be considered a measurement on population.
Mean =
= 
Variance =

Standard Deviation =

= 0.73P
