Answer:

Explanation:

a. cycle time = Total time available/ production rate required

cycle time = (60*60)/180 = 3600/180 = 20sec per unit

b. theoretical minimum for the number of work-stations that Rosenberg can achieve in this assembly line.

Total task time = 12+15+8+5+20 = 60

theoretical minimum for the number of work-stations = Total task time/cycle time

theoretical minimum for the number of work-stations = 60/20 = 3stations

c. idle time

standard hour for the job is calculated as

standard hours allowed for actual production = unit produced * labor time required

The question does not contain the required information to solve it. Information such standard hours is not given.

Economic theory and the data in the table show that the average total cost curve and the marginal cost curve are related in that the MC curve passes through the minimum point of the ATC curve.

<h3>What is the relationship between the MC and ATC curves?</h3><h3 />

The data given by the table (which is accurately filled up) shows that the MC curve will intersect the ATC curve at its lowest point.

We see this from the fact that before the lowest ATC of 0.107, the marginal cost was less than the ATC. After the lowest ATC however, the marginal cost becomes higher than the ATC.

This shows that the MC curve intersected the ATC at its lowest point of 0.107 and then kept rising above it.

Find out more on the MC curve at brainly.com/question/9335427.
