Answer:
Class Boundary = 1 between the sixth and seventh classes.
Step-by-step explanation:
               Lengths (mm)                   Frequency
1.                  140 - 143                                  1
2.                 144 - 147                                 16
3.                 148 - 151                                 71
4.                 152 - 155                              108
5.                 156 - 159                               83
6.                 160 - 163                                18
7.                  164 - 167                                 3
The class boundary between two classes is the numerical value between the starting value of the higher class, which is 164 for the 7th class in this case, and the ending value of the class of the lower class, which is 163 for the 6th class in this case.
Therefore the class boundary between the sixth and seventh classes 
= 164 - 163  = 1
Therefore Class Boundary = 1.
It can be seen that class boundary for the frequency distribution is 1.
If we take the difference between the lower limits of one class and the lower limit of the next class then we will get the class width value.
Therefore, Class width,
w = lower limit of second class - lower limit of first class
    = 144 - 140
    = 4
 
        
             
        
        
        
Answer:
y=-3x
Step-by-step explanation:
The meaning of direct proportion is that the ratio remains the same, and the ratio will only remain the same if y= a constant number into x
 
        
             
        
        
        
Answer:
1.33 liters
Step-by-step explanation:
Volume of any shape is given by cross sectional area multiplied by height. Therefore, V=Ah
Where A is area and h is height
Since their cross sections are the same, then volume depends on height.
If 12cm equals 2 liters
8cm equals x
X=(2*8)/12=1.3333333333333 liters 
Approximayely, the smaller pail has capacity of 1.33 liters
 
        
             
        
        
        
Answer:
f(x+2) = 3(x+2)^2 + 2(x+2) + 1
Step-by-step explanation:
Replace x with x+2 and you get the solution above. Hope this helps!
