Answer:
The correct answer to the following question will be "280 units".
Step-by-step explanation:
The given values are:
Mean = 200
Standard deviation = 30
Let's ask that the supplier needs to reach 99.9% of the standard of operation. To reach this quality of operation, she has to preserve an inventory of
Now,
⇒ 
On putting the values, we get
⇒ 
⇒ 
⇒ 
290 units would then accomplish a level of service of 99.9%.
Half unpurchased units can indeed be purchased at $30000 i.e. no failure. If he requests 300, there will be losses on 5 products that are unsold.
Hence, ordering 280 units seems to be preferable

Step-by-step explanation:
Factor trees help you find the prime factorization of a number by breaking down the number by what two numbers equal the number you are trying to find the prime factorization of.
Answer:
Step-by-step explanation:
The photo for the question is not given. I have searched and attached it.
From the attached photo, the inequality is
-2x/3 + 9 > 7
By simplifying, subtract 9 from both sides of the inequality. It becomes
-2x/3 + 9 - 9 > 7 - 9
- 2x/3 > - 2
Multiplying both sides of the inequality by - 3/2, the inequality symbol would change due to the negative sign. It becomes
- 2x/3 × 3/2 < - 2 × - 3/2
x < 3
Therefore,
Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
