I think it’s D) 9 because when you find the mean of a set of values you are taking into account and adding all of the numbers, and then dividing them by how many numbers there is, so the mean would be summarizing all of them, hope this helps
The response is
<span>x greater than or equal to -9
</span>proof
8x - (5x + 4)>= -31, 3x- 4>= -31, 3x >= -27, <span>x>= -27/3= -9
so </span><span>x greater than or equal to -9</span>
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
