Answer:
19.24 weeks
Step-by-step explanation:
Given that;
Mean, m = 18
Standard deviation, s = 3
Break down cost = 2000
Preventive maintenance cost = 1400
The optimal preventive maintenance level is Given by :
Mean + service level * standard deviation
Service level = preventive maintenance cost / (breakdown cost + preventive maintenance cost)
Hence,
Service level = 1400/(1400+2000) = 1400 / 3400
Service level = 0.4117647
Optimal preventive maintenance level :
18 + (0.4117647 * 3)
18 + 1.2352941
= 19.235
= 19.24 weeks
The answer is B.
The ratio is multiplied by three so 5 times 3 is 15 and 2 times 3 is 6.
Answer:
The motorcycle is 154inches long.
Step-by-step explanation:
the formula = part/whole=percent/100
x/110 = 40/100
x*100=110*40
x*100=4400
<u>x*100</u>=<u>4400</u>
100 100
x=44
The bike is 110inches long and the motorcycle is 40% longer all u have to do is add what we just got which was 44 to 110= 44+110=154.
Hope that made sense :)

Answer:
Option A.
Step-by-step explanation:
Note: Let as consider, we have to find the total amount after 9 years.
It is given that,
Principal amount = $1000
Rate of compound (yearly) interest = 15% = 0.15
Time = 9 year
The formula for total amount is
where, P is principal, i is rate of interest and n is number of years.
Substituting P=1000, i=0.15 and n=9, we get
So, the total amount after 9 years is $3517.88.
Therefore, the correct option is A.
