Alice searches for her term paper in her filing cabinet, which has several drawers. She knows thatshe left her term paper in dra

katen-ka-za [31]

You made a mistake with the probability $p_{j}$ , which should be $p_{i}$ in the last expression, so to be clear I will state the expression again.

So we want to solve the following:

Conditioned on this event, show that the probability that her paper is in drawer $j$ , is given by:

(1) $\frac{p_{j} }{1-d_{i}p_{i} } , if j \neq i,$ and

(2) $\frac{p_{i} (1-d_{i} )}{1-d_{i}p_{i} } , if j = i.$

so we can say:

$A$ is the event that you search drawer $i$ and find nothing,

$B$ is the event that you search drawer $i$ and find the paper,

$C_{k}$ is the event that the paper is in drawer $k, k = 1, ..., n.$

this gives us:

$P(B) = P(B \cap C_{i} ) = P(C_{i})P(B | C_{i} ) = d_{i} p_{i}$

$P(A) = 1 - P(B) = 1 - d_{i} p_{i}$

Solution to Part (1):

if $j \neq i$ , then $P(A \cap C_{j} ) = P(C_{j} )$ ,

this means that

$P(C_{j} |A) = \frac{P(A \cap C_{j})}{P(A)} = \frac{P(C_{j} )}{P(A)} = \frac{p_{j} }{1-d_{i}p_{i} }$

as needed so part one is solved.

Solution to Part(2):

so we have now that if $j$ = $i$ , we get that:

$P(C_{j}|A ) = \frac{P(A \cap C_{j})}{P(A)}$

remember that:

$P(A|C_{j} ) = \frac{P(A \cap C_{j})}{P(C_{j})}$

this implies that:

$P(A \cap C_{j}) = P(C_{j}) \cdot P(A|C_{j}) = p_{i} (1-d_{i} )$

so we just need to combine the above relations to get:

$P(C_{j}|A) = \frac{p_{i} (1-d_{i} )}{1-d_{i}p_{i} }$

as needed so part two is solved.

Kingbird, Inc. purchased merchandise with an invoice price of $3200 and credit terms of 2/9, n/30. Assuming a 360-day year, what

Tatiana [17]

Answer:

80%

Step-by-step explanation:

Data provided as per the question

Number of days in a year = 360 days

Discount provided = 2%

Total net credit period = 30

The calculation of implied annual interest rate inherent in the credit terms is shown below :-

$Inherent\ in\ the\ credit\ terms\ = \frac{Number\ of\ days\ in\ a\ year}{Total\ net\ credit\ period\ - Remaining\ days}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - (30\ -\ 9)}\times 2\%$ $Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - 21}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \frac{360}{\ 9}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \ 40\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \ 80\%$

Therefore for computing the inherent in the credit terms we simply applied the above formula.
