Answer:
C) Takt times at workstations are dynamic.
Explanation:
A fixed-position layout can be regarded as a layout that allow products to stay in one place, and movement of workers and machinery can be moved to it once needed. Some of the Products that are not possible to move are airplanes, construction projects as well as ships. Fixed-position layout is usually used when dealing with product which are too large or heavy to move. Disadvantages is that it takes space, and administration burden is usually high. Factors that could complicate the techniques for addressing the fixed-position layout are;
✓There is limited space at virtually all sites.
✓The volume of materials needed is dynamic.
✓At different stages of a project, different materials are needed; therefore, different items become critical as the project develops.
With stocks of 8% for A and 16% for B, The global minimum variance is given as 10.5 percent
<h3>How to solve for the variance</h3>
The expected return of the stock for the country a is given as 0.05
The Weight of this country's stock market WA = 0.5
The expected return of the stock for the country a is given as 0.16
The Weight of this country's stock market Wb = 0.5
Expected Return of the portfolio can be calculated as
= (WA x RA) + (WB * RB)
Expected Return of the portfolio = (0.5x 0.05 ) +(0.5*0.16)
= 0.105
= 10.5%

Answer:
keep producing in the short run but exit the industry or go out of business in the long run
Explanation:
A perfect competition is characterised by many buyers and sellers of homogeneous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.
In the long run, firms earn zero economic profit. If in the short run firms are earning economic profit, in the long run firms would enter into the industry. This would drive economic profit to zero.
Also, if in the short run, firms are earning economic loss, in the long run, firms would exit the industry until economic profit falls to zero.
A firm should shut down in the short run if price is less than average variable cost. But since the diner's price is greater than average variable cost, it should continue production.
A firm should exit the industry in the long run if price is less than average total cost. the diner's price is less than average total cost, so it should shut down in the long run
