Answer:

Explanation:

Number of bulbs = 20

Success of a bulb lightning properly = 0.92

Success of a bulb not lightning properly = 0.08

We have to find the probability of atmost 3 bulbs not lightning properly -

The random Variable X follows binomial distribution

= 0.929385

Mean and variance of bulbs in a string that are not lightning properly is given by

Mean of binomial distribution or E(X) = n*p = 20*0.08 = 1.6

Variance of binomial distribution or V(X) = n*p*(1-p) = 20*0.08*0.92 = 1.472

ou are considering implementing a lockbox system for your firm. The system is expected to reduce the collection time by 3 days.
Taya2010 [7]

The net present value of this lockbox arrangement is $1,205,378.06.

Since you are considering implementing a lockbox system for your firm, and on an average day, your firm receives 1,370 checks with an average value of $ 880 each, and the daily interest rate on Treasury bills is 0.01 percent, and the bank charge per check would be $ 0.25, to determine what is the net present value of this lockbox arrangement, the following calculation must be performed:

  • ((1370 x 880) x 1.0001) - (1370 x 0.25) = X
  • 1,205,720.56 - 342.5 = X
  • 1,205,378.06 = X

Therefore, the net present value of this lockbox arrangement is $1,205,378.06.
