Given that the production of n stalks of corn planted has been modeled by (2n^2-2n), then the approximate ears of corn produced by 3 stalks will be given by:
2n^2-2n
plugging in n=3 in the formula we get:
2(3)^2-2(3)
simplifying we get:
2(9)-6
=18-6
=12
the answer is: 12 ears
        
             
        
        
        
Answer:
4.3
Step-by-step explanation:
Apply trigonometric ratios to find the answer. 
Firstly, we need to find the measure of angle theta. In order to do this, we will use triangle BAD.
From angle theta, the trigonometric ratio sine can be used:
sinθ = 
After we find the value, we take the inverse sine of it and the result is approximately 50.7 degrees.
Now, knowing that angles BAD and CAD are the same, we can solve for CD using trigonometric ratio sine. 
sin50.7 = opposite/hypotenuse
sin50.7 = CD/5.5
sin50.7 * 5.5 = CD
4.3 ≈ CD 
 
        
             
        
        
        
Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is 



 
        
             
        
        
        
Answer: 10.75
Steps: 
After 110miles, it used 2.75gallons
Therefore, the amount of gas used per mile is: 100/2.75= 40 gallon per mile 
So after 430miles, the number of gallons used: 430/40 = 10.75 gallons
