Answer:
A) 1.111
B) 0.889
Explanation:
given data :
outer diameter of connecting rods = 1 ± 0.01 inch
sample mean outer diameter = 1.002 inches
standard deviation = 0.003 inches
A) Calculating the Cp of the process
mean = 1.002
Standard deviation = 0.003
LSL = 1 - 0.01 = 0.99
USL = 1 + 0.01 = 1.01
= 
= 1.111
B) calculate Cpk
mean = 1.002, LSL = 0.99, USL = 1.01 , deviation = 0.003
![Cpk = min[\frac{mean-LSL}{3* deviation} , \frac{USL- mean}{3*deviation} ]](https://tex.z-dn.net/?f=Cpk%20%3D%20min%5B%5Cfrac%7Bmean-LSL%7D%7B3%2A%20deviation%7D%20%2C%20%5Cfrac%7BUSL-%20mean%7D%7B3%2Adeviation%7D%20%5D)
= min [(0.012/0.009) , (0.008/0.009) ]
= min [ 1.333, 0.889 ]
hence Cpk = 0.889
Answer:
Option C is the answer
Explanation:
The degree of operating leverage is measured by dividing the contribution margin by operating income.
The degree of operating leverage (DOL) is the ratio of contribution margin to operating income. It measures how much the operating income of a company will change in response to a change in sales. A Companies that have higher proportion of fixed costs to variable cost will have greater levels of operating leverage.
Answer:
Instructions are listed below
Explanation:
Giving the following information:
The high-low method involves taking the highest level of activity and the lowest level of activity and comparing the total costs at each level.
Mountain has recorded the following for the past nine months:
January:
Number of Cavities= 375
Total cost= $5,300
February:
Number of Cavities 500
TC= 5,850
March
Number of Cavities 350
TC= 5,200
April
Number of Cavities 600
TC=6,250
May
Number of Cavities 325
TC= 5,150
June
Number of Cavities 475
TC= 5,700
July
Number of Cavities 525
TC= 6,100
August
Number of Cavities 575
TC= 6,300
September
Number of Cavities 450
TC= 5,550
A) Variable cost= (Highest activity cost - lowest activity cost) / (Highest activity units - lowest activity units)
Variable cost= (6300 - 5150) / (600 - 325)= 4.18 per unit
Fixed cost= HACost - (variable cost per unit * HAUnits)= 6300 - (4.18*600)= 3792
Fixed cost= LACost - (variable cost per unit* LAUnits)= 5150 - (4.18*325)= 3792
B) Q= 400
Total cost= 3792 + 4.18*400= $5464
Answer:
<u><em></em></u>
- <u><em>Law of demand</em></u>
<u><em></em></u>
Explanation:
Indeed, the <em>law of demand </em>is that the price and quantity demanded are inversely related. <em>Ceteris paribus</em>, the economist say. It is a latin expression that means "<em>other things equal</em>".
As the resources are, per definition, scarce, the consumers, ecomomic agents who buy the products, need to allocate the money among the different goods and services that the market puts at their disposal.
And they allocate the resources in a intelligent way: they "calculate" the utility of each product considering the cost. If the price increase, the ratio of utility to cost decreases and the consumer will diminish the quantity demanded for that good. If the price decrases, the utility to cost ratio increases and the quantity demanded will increase.
