Answer:
3x+6
x+x+2+x+4
» You can group the like terms, in this case, the x's and the numbers.
x+x+x+2+4
3x+6
 
        
             
        
        
        
Geometric series are in the form of

Where a is the first term and r is the common ratio .
And it is given that




r=-3,2
So the first five terms are

= 2-6+18-54+162 or 2+4+8+16+32
= 122 or 62
 
        
                    
             
        
        
        
The answer would be y=-13x+7
hope this helps ;]

Answer:
the x² test statistic 13.71
Option a) 13.71 is the correct answer.
Step-by-step explanation:
Given the data in the question;
Feeder                     1      2      3       4
Observed visits;  60   90   92    58
  60   90   92    58
data sample = 300
Expected  = 300 / 4 = 75
 = 300 / 4 = 75
 the x² test statistic = ?
 = ∑[ (
 = ∑[ ( -
 -  )²/
)²/ ]
]
 = [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]
 = [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]
 = [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]
 = [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]
 = 13.7066 ≈ 13.71
 = 13.7066 ≈ 13.71
Therefore, the x² test statistic 13.71
Option a) 13.71 is the correct answer.
