Answer:
1). Mean = 2.275
2). Median = 2 vehicles
Step-by-step explanation:
From the given table,
Number of vehicles (x)         Frequency (f)      (f)×(x)             Cumulative freq.
                   0                                    11                  0                           11
                   1                                     52                52                        63
                   2                                    66                132                      129
                   3                                    35                105                      164
                   4                                    19                  76                       183
                   5                                    12                  60                       195
                   6                                     5                  30                       200
                                                                           
Number of households = 200
Mean = 
           = 
          = 2.275
Median = value of  observation
 observation
              = value of  observation
 observation
              = Value of 100.5th observation
              = Since 100.5th observation lies in the row of cumulative freq. = 129
              = 2
Therefore, median number of registered vehicles per California household 
= 2 vehicles
 
        
             
        
        
        
Answer:
86
Step-by-step explanation:
 
        
             
        
        
        
Area of a circle = pi • r^2
We need to isolate for r.
A/pi = r^2
r = sqrt(A/pi)
r = sqrt(30.8/pi)
r = 3.1311251164
Diameter = 2r
Diameter = 6.26225023
Diameter = 6.3 m
        
             
        
        
        
Answer:
The slope is a positive linear slope
The slope is 2
The y-intercept is -4
The equation of this line would be: y = 2x - 4
Step-by-step explanation:
y = mx + b format
m = slope
b = y-intercept
and x and y are the x and y components
 
        
             
        
        
        
-2(8p+2)-3(2-7p)-2(4+2p)=0
mutiply the first bracket by -2 
(-2)(8p)= -16p
(-2)(+2)= -4
mutiply the second bracket by -3
(-3)(2)= -6
(-3)(-7p)= 21p
mutiply the third bracket by -2 
(-2)(4)= -8
(-2)(+2p)= -4p
-16p-4-6+21p-8-4p= 0
-16p+21p-4p-4-6-8= 0 ( combine like terms)
5p-4p-4-6-8= 0
p-4-6-8= 0
p-10-8= 0
p-18= 0
move -18 to the other side to get p by itself
sign changes from -18 to +18
p-18+18= 0+18
p= 0+18
Answer: p= 18
