The appropriate level of safety stock is typically determined by
Lady_Fox [76]

Answer: Choosing the level of safety stock that assures a given service level.

Step-by-step explanation:

Safety Stock provides a buffer against stockouts, ensuring that service or production continues if there is a problem with inventory supply. Such problems can vary from price fluctuations to a supplier's inability to fill an order.

The goal of safety stock is not to totally eliminate the risk of stockout as this would be too expensive and impossible in some industries such as hospitality where inventory has a short shelf life.

While safety stock may reduce the stockout cost, it is not the primary consideration in determining the level of safety stock.

How many total circles will be used if there are 20 rows of circles? Show all calculations.
Rashid [163]

Answer:

210

Step-by-step explanation:

As there is one circle in first row, 2 circles in 2nd row and three in third row, which clearly implies that the number of circles in each row is equal to the row number. So, we have to calculate sum of first 20 numbers to calculate the total number of circles.

n=20

Total Circles=(n(n+1))/2

=(20 (20+1))/2

=(20(21))/2

=  420/2

=210

So the total number of circles will be 210.
