Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.
Answer:
Debit : Allowance for doubtful debts = $2900
Credit : Accounts receivables = $2900
Explanation:
An account for allowance for doubtful debts is a contra account created, predicting that certain debtors will not be able to pay for the goods and services they purchased. This may be based on historical experiences. Doubtful debts aren’t officially uncollectible, it is simply an estimation made, but bad debts are, where you have officially written off a certain accounts receivable as uncollectible.
An allowance for doubtful debts is recorded in the balance sheet, directly under accounts receivables. Bad debts are recorded as an expense in the income statement. When there is an allowance for doubtful debts, the bad debts account is debited and the allowance for doubtful debts account is credited.
According to the question, the balance was $2,200 (Cr) in the allowance for doubtful debts account. The initial expected amount for allowance for doubtful debts was $5100 (Cr). This means that the difference was the amount that was declared as uncollectible and officially written off i.e. bad debts. Thus $2900 ($5100 -$2200) would have been confirmed as bad debts.
The entry to record the above transaction is:
Debit : Allowance for doubtful debts = $2900
Credit : Accounts receivables = $2900
Answer:
No, he should <u>not</u> pick up the $100 bill
Explanation:
If his salary were those $20 billion (20,000,000,000) by a year. Let's find out how much this is by a second.
First let's find out how much is that salary by <em>a day</em>, then by <em>an hour</em>, then by <em>a minute</em> and finally by <em>a second</em>.
So he would be losing money if he picks up the $100 bill, because he would be missing 634 dollars per second.
Answer:
We will use the following equations for this problem
a. (Initial cost Estimated output) × Actual yearly output
b. (Depreciable cost Yearly output) × Estimated output
c. Depreciable cost Yearly output
d. (Depreciable cost Estimated output) × Actual yearly output
