Answer:
Total annual inventory cost = $480
c) 480
Step-by-step explanation:
given data
annual demand for the oil filter = 1200 units
ordering cost per order S = $80
holding cost of carrying 1 unit = $1.2 per year
lead time = 12 working days
number of working days = 360 days
solution
we get here economic order quantity that is express as
economic order quantity = ...............1
here D is annual demand and S is ordering cost and H is per unit cost
so put here value and we get
EOQ =
EOQ = 400 units
and
Annual ordering cost = annual demand × ordering cost ÷ order size .........2
and here
No orders (Q) = annual demand ÷ order size ...........3
Q = 1200 ÷ 400
Q = 3 orders
so
Annual ordering cost = ordering cost × number of order ................4
put here value
Annual ordering cost = 80 × 3
Annual ordering cost = $240
and
Annual carrying cost = average inventory × per unit cost ..........5
and
average inventory = EOQ ÷ 2 ...........6
Annual carrying cost = (EOQ × H) ÷ 2
put here value and we get
Annual carrying cost = 400 × 1.2 ÷ 2
Annual carrying cost = $240
and
so here Total annual inventory cost = Annual ordering cost + Annual carrying cost .........................7
Total annual inventory cost = $240 + $240)
Total annual inventory cost = $480
Answer:
And we can find this probability using excel or the normal standard tabe and we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the temperatures of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using excel or the normal standard tabe and we got:
