Answer:
The assembly line efficiency is 4.17% (to 2 decimal places)
Explanation:
Efficiency is a measure of productivity that is used to determine how well a target is achieved, by finding the ratio of the actual output to the expected output. In this example, the number of units is the output of the assembly line, and the assembly line efficiency is calculated as follows:
Assembly line efficiency = (actual output) /(required output) × 100
actual output = 25 minutes
if 5 minutes = 1 unit
∴ 25 minutes = 1/5 × 25 = 5 units
∴ actual output = 5 units
required output = 120 units
∴ efficiency = 
= 4.17%
Answer:
U-shaped
Explanation:
Since the marginal product of labor is decreasing, the average variable costs and marginal costs will be increasing at all points, but the average fixed costs will be decreasing. That is why the average total costs (which includes both variable and fixed costs per unit) will be U-shaped since they will fall at the beginning when the decrease in marginal product of labor is small, bu then will increase as the marginal product of labor falls even more.
I think it might be C, I'm not sure but I think it is.
Hope this helped. Have a great day! :D
