Answer:
a=2
b=6
Step-by-step explanation:
Assuming a uniform distribution and that a ≤ x ≤ b, if f(x) = 1/4, then:

If P(X > 4) = 1/2, then:

The values for a and b are, respectively, 2 and 6.
10+6x=4x-4
6x-4x=-4-10
2x=-14
x-7
10=6(-7)=-32
4(-7)-4=-32
=-32
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
Answer:
The answer is x=4
Step-by-step explanation:
so you have -4x-2=-18
so we get rid of -2 by adding it to the other side so you'll end up having -4x=-16
you then divide that by -4 on both sides and get x=4 as your remaining answer
7/8 + 7/12 = 35/24 = 1 11/24
