For this case we have the following functions:

We must find
. By definition of compound functions we have to:

So:
Taking into account that:

Different signs are subtracted and the major sign is placed.

Finally we have to:

Answer:

Answer:
A. The increase in the number of pounds a boy gains each year.
Step-by-step explanation:
A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is
y = 1.73x + 80.13 ............ (1)
where x represents the age of the boys and y represents the weight of the boy corresponding to his age.
Therefore, the slope of the equation (1) represents the increase in the number of pounds a boy gains each year. (Answer)
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.
Step-by-step explanation:
Answer
1/20
Step-by-step explanation:
Compound Probability=Probability1*probability2
Probability that the 1st student chosen is team leader:1/5
The 2nd student chosen is assistant leader:1/4 as one person is already chosen
multiply 1/5 by 1/4 you get 1/20
B. The independent variable is the driving speed, and the dependent variable is the gasoline consumption.
Gasoline consumption will either increase or decrease based on the driving speed of the car.
The weight of the car is not essential in determining the relationship between driving speed and gas consumption.
