12:12 is the ratio because each fish can grow up to be 12 inches long so 12 gallons would be in the tank per fish.
There would be infinite answers
The quadratic term is 2x^2.
The <em><u>correct answer</u></em> is:
c)75.4 to 94.6
Explanation:
The formula for a confidence interval is:
,
where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.
Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:

The answer is f when 2,3 is put in for the x and y then 18 should come out 3×2=6
4×3=12 12+6=18
