Answer: The observed ratio is different from the expected ratio.
Step-by-step explanation:
Since we have given that 
Expected ratio :
Ratio of blue flowered plants to white flowered plant = 3:1
Observed results:
Number of blue flowered plants = 35
Number of white flowered plants = 14
So, Ratio of blue flowered plants : white flowered plants 

So, 5:2 ≠ 3:1
Hence, the observed ratio is different from the expected ratio.
 
        
             
        
        
        
We know that 2/3 of all students watch TV shows on their computers.

(x - 4)(2x + 3)
Using foil:
2x^2 + 3x - 8x - 12
Simplify.
2x^2 - 5x - 12 is the product after using FOIL.
