Answer: B. The stocks have a yield 6.84 percentage points greater than that of the bonds. 
Step-by-step explanation:
Firstly, the yield for stocks will be calculated as:
= return/ investment cost
= $3.15/$ 21.38 
= 0.14733395 
= 14.73%
The yield for bonds will be calculated as:
= Return/Investment cost
Return = 1,000 x 8.3% = 83
Investment cost = 1,000 x 105.166/100 = 1051.66
Yield = 83/1051.66 
= 0.07892284 
= 7.89%
Then, the difference between the yield will be:
= 14.73% - 7.89%
= 6.84%
Therefore, the stocks have a yield 6.84 percentage points greater than that of the bonds. 
 
        
             
        
        
        
Answer:
5.33 unit
Step-by-step explanation:
logically FA = EA - EF = 13.33-8 = 5.33 units
Since, E, F and A all lie on the same line EA . The information ED=  units is redundant. Therefore we can say that FA= 5.33 unit
 
        
             
        
        
        
Answer:
2g/cm³
Step-by-step explanation:
p=m/v
mass=80g
volume=4cm x 2cm x 5cm = 40cm²
80g/40cm²=2
density = 2 g/cm³
