4. Average daily demand for a product is normally distributed with a mean of 40 units and a standard deviation of 8 units. Lead time is fixed at 30 days. What reorder point provides for a service level of 95 percent (z=1.65)? (2 points)

1236.15

Step-by-step explanation:

Data provided

Daily demand (d) = 40 units

Standard deviation = 8 units

Lead time (L) = 30 days

The Service level of 95 percent z value = 1.65

The computation of the reorder point is shown below:-

Reorder point = demand during lead time + safety stock

= 1236.149689

or

= 1236.15

Therefore the correct answer is 1236.15

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
