Answer:
377/389
Step-by-step explanation:
Add all the values together:
12 + 352 + 25 = 389
352 visitors purchased one costume. 25 visitors purchased more than 1 costume. Add these values.
352 + 25 = 377
Put this value and the number of visitors to the site total together as a fraction
377/389
This fraction can't be simplified. This is the answer
The answer to the problem is x=3
Answer: 93 units should be ordered.
Step-by-step explanation:
Since we have given that
Standard deviation = 4
Average = 30 units
Number of weeks in order interval = 3
Desired service level = 97.5%
Number of units on hand = n = 43
So, the expected value would be
![E[x]=30\times (3+1)+1.96\times 4\sqrt{3+1}-43\\\\E[x]=30\times 4+1.96\times 4\times 2-43\\\\E[x]=120+15.68-43\\\\E[x]=92.68\approx 93](https://tex.z-dn.net/?f=E%5Bx%5D%3D30%5Ctimes%20%283%2B1%29%2B1.96%5Ctimes%204%5Csqrt%7B3%2B1%7D-43%5C%5C%5C%5CE%5Bx%5D%3D30%5Ctimes%204%2B1.96%5Ctimes%204%5Ctimes%202-43%5C%5C%5C%5CE%5Bx%5D%3D120%2B15.68-43%5C%5C%5C%5CE%5Bx%5D%3D92.68%5Capprox%2093)
Hence, 93 units should be ordered.
