Answer:
b. 0.67
Explanation:
UCL = 1 + 0.10
= 1.10 inch
LCL = 1 - 0.10
= 0.9 inch
standard deviation = 0.005 inch
mean = 1 inch
Cpk
= min[(UCL - mean)/(3*standard deviation) , (mean - LCL)/(3*standard deviation))]
= min[(1.10 - 1)/(3*0.05) , (1 - 0.9)/(3*0.05))]
= min[0.67 , 0.67]
= 0.67
Therefore, Theprocess capability index (Cpk) if the long-run process mean is 1 inch is 0.67
Answer:
Answer is explained in the attachment.
Explanation:
Answer:sales must have amounted to:$704,000
Explanation:
Contribution ratio = Sales ratio - Variable cost ratio
= 100%- 75%
=25%
Sales to break even = Fixed expenses / Contribution margin ratio
Therefore,
Fixed expenses = Sales to break even x Contribution margin ratio
=$840,000 x 25%
=$210,000
Contribution margin can also be calculated as
Fixed expenses- Operating loss
=$210,000 -$34,000
=$176,000
Sales = Contribution margin/ Contribution ratio
= $176,000/25% =$704,000
Answer:
A) discrete random variable.
Explanation:
Discrete random variables can assume only a finite number of values, and their combined total probabilities must equal 1.
On the other hand, continuous random variables can take any value with an interval or collection of intervals, which means that the possible values are infinite.
A complex random variable is a combination of two real random variables that have rel and imaginary parts.
Answer:
Different communication methods are used in different circumstances because sometimes a certain method will be more effective in terms of cost, time and impact, and sometimes it will be more appropriate.
