Answer:
The mean phenotype code is 2.72
The median phenotype code is 2.52
The mode phenotype code is 2.
The midrange of the phenotype codes is 2.52
B Only the mode makes sense since the data is nominal.

Answer:
(2) (100, 300)
Step-by-step explanation:
One wave can be divided on 4 parts, as show on the picture.
Since a length of one whole wave equals 400, a length of each part is  nanometers.
 nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
 
        
             
        
        
        
Answer:
B(-5,5).
Step-by-step explanation:
It is given that midpoint of AB is M (-6,1).  
Coordinates of A are (-7,-3 ).
We need to find the coordinates of point B.
Let coordinates of point B are (a,b).
 
Midpoint of AB is
 
 
On comparing both sides, we get
 
 
 
 
 
 
 
 
Therefore, the coordinates of B are (-5,5).
 
        
             
        
        
        
<u>Given</u>:
Given that the side length of the cube is 1.8 cm
We need to determine the lateral surface area of the cube.
<u>Lateral surface area of the cube:</u>
The lateral surface area of the cube can be determined using the formula,

where a is the side length.
Substituting a = 1.8 in the above formula, we get;

Squaring the term, we get;

Multiplying, we get;

Thus, the lateral surface area of the cube is 12.96 cm²
