Answer:
Materials quantity variance and labor efficiency variance.
Explanation:
Material quantity variance is defined as the difference that exists between the actual amount of a material that is used in production and the expected amount to be used. It measures the efficiency with which a raw material is converted into product.
MQV is calculated by multiplying standard price of material by difference between standard quantity and actual quantity.

  The ability to automatically detect the occurrence of an abnormality, thereby helping achieve quality at the source, is jidoka
Therefore, Jidoka's definition is best understood as "automation". This means manual automation or autonomous automation. The origin of Jidoka can be traced back to Toyota Motor Corporation, which was founded by Sakichi Toyoda as a textile manufacturer.
A famous example of Jidoka is his Model G for Toyoda Automatic Loom, invented and patented in 1925 by Sakichi Toyoda (1867–1930). This is one of the many looms invented by this inventor, but perhaps his most famous. This loom could be operated almost unmanned. Jul 31, 2018
Automation is a commonly used term in Lean Manufacturing, widely considered one of the pillars of the Toyota Production System, the other being Just in Time (JIT). The term "Jidoka" is often used to impress others, but the idea behind it is less common outside of Toyota.

The answer is: averaged over time, Sheridan attends worship services regularly.
When we use principle of aggregation, we would not rely on single measurement to make a representation of a person's behavior. We rely more on multiple sets of measurements.
From the case above, Sheridan not attending the services for two weeks could be explained by things such as personal issues or physical illness. Since she considers herself as religious who attend regularly, it is very likely that averaged over time, Sheridan attends worship services regularly.

Under the condition that country X can manufacture cars more cheaply. An absolute advantage devours in a country if it makes good over alternative country and uses a smaller amount of wealth to yield that good. The result of a country’s natural legacy is the absolute advantage. Another example is extracting oil in Saudi Arabia is pretty much just a matter of drilling a hole. Generating oil in other countries can is essential substantial exploration and costly technologies for drilling and extraction if certainly they have any oil at all. The United States devours about the richest farmland in the world which manufacture it at ease to grow corn and wheat than in many other countries. Guatemala and Colombia partake environment particularly suitable for growing coffee. Chile and Zambia have about of the world’s richest copper mines. As some have claimed that geography is destiny. Chile will bargain copper and Guatemala will harvest coffee and they will trade. When each country has a product others necessity and it can be manufactured with fewer resources in one country over another then it is easy to visualize all parties do good from trade. Thinking about trade just in relations of geography and absolute advantage is incomplete. Trade actually happens because of comparative advantage.
