Answer:
A) Horsepower is the independent variable
D) The scatter plot shows a negative correlation
Step-by-step explanation:
Independent variable goes on the x-axis, it does not depend on another.
In this case, horsepower is the independent variable.
Negative correlation is a relationship between two variables in which one variable increases as the other decreases.
In this case, the scatter plot shows a negative correlation.
X= 9/2, 15/2
decimal form: 4.5,-7.5
mixed number form: 4 1/2, -7 1/2
The general way to work this out is to solve the general expression for
the remaining quantity versus half-life, using logarithms. But that's not
necessary with these numbers.
Look at the numbers:
-- 3 mg is 1/4 of 12 mg.
-- 1/4 is the product of (1/2) x (1/2).
-- So the 3 mg is what's left of 12 mg after 2 half-lives.
The 26 minutes must be two half-lives.
-- The half-life of that substance is 26/2 = <em>13 minutes</em>.
