Let A be the event
and B be the vent
. Since the intersection of the events
, the events A and B are mutually exclusive.
The number is either odd or even. Since
, the events are mutually exclusive and exhaustive.
Correct choice is "the number is either odd or even".
So first we need to find approximately the number of total students.
Rock I would say is about 200 people. Country, 100, Rap, 255, Classical, 64 as said before, and Blues, 80.
So if we add these all up we can find the total students.
200 + 100 + 255 + 64 + 80
699
Now the relative frequency is how many times something appears in a group.
Classical appears 64 times in about 700 people.
So, 64/700, is closest to the 0.9 selection.
Answer: 8,000,000
Step-by-step explanation:
Given the following :
EOQ = 4000
Ordering cost (S) = $25
Carrying cost = 25% of unit cost
Cost per load = $100
Let annual demand = D
EOQ = sqrt[ ( 2 * S * D) / H]
Holding cost = H = 0.25 × $100 = $25
Hence,
4000 = sqrt[ ( 2 * 25 * D) / 25]
4000 = (50D /25)^1/2
Square both sides
4000² = 50D / 25
16,000,000 × 25 = 50D
400000000 = 50D
D = 400000000 / 50
D = 8,000,000
Hence, annual demand = 8,000,000
