Answer: Human factor research
Explanation:
From the question, we are informed that a manager of a bank branch is concerned about the number of mistakes the tellers were making, so he started manipulating different aspects of the environment in the bank to see what effect each has on the tellers' performance. 
We are further told that he examined factors such as the lighting, temperature, and the volume of the music playing in the bank.
He's using the human factor research approach. Here, the capabilities of human beings are determined through strength, vision, flexibility etc.

I just recently learned this myself due to buying an old farm house that was built in the 1970's. Asbestos is commonly found in buildings and structures built before 1981 and is a very harmful thing if inhaled into the body.
 
        
                    
             
        
        
        
Answer:
$2,189.76 
Explanation:
<em>The price of a bond is the present value (PV) of the future cash inflows expected from the bond discounted using the yield to maturity.</em>
<em>The price of the bond can be calculated as follows:</em>
<em>Step 1</em>
<em>PV of interest payment</em>
Interest payment =( 5.94%× $2000)/2
= $59.4
Semi annual yield = 5.1/2 = 2.6%
PV of interest payment 
= 59.4× (1-(1.026)^(-20×2))/0.026)
= 59.4 × 24.41400537
=<em>$ 1,450.19</em>
Step 2 
<em>PV of  redemption value</em> 
=  2,000 × (1+0.051)^(-20)
= 2,000 × 0.369781925
=   739.56 
 
Step 3
<em>Price of bond  </em>
= $1,450.19 + $739.56  
=$2,189.76 
 
        
             
        
        
        
Answer:
1. 1,000 bushels of wheat
2.  d) A situation where one country does not engage in trade with other
Explanation:
1 & 2. Autarky refers to a situation where a country does not engage in trade with other countries but rather relies on its own production capacities to feed the consumption in the country.
 Autarkies in the current world are not a thing because countries trade with each other. Even North Korea trades with Russia, China and others. 
In an Autarky situation therefore, the United States would only be able to consume the wheat that it produces itself which according to the question is 1,000 bushels of wheat.
