Solution: The test score that the teacher should expect from a student who did not attend her course is 37.
<u>Explanation:</u>
The teacher's equation for the line of best fit is
We know the equation for the line of the best fit is:
Where:
is slope of the equation. It represents the rate of change in y as one unit change in x.
is the intercept. It represents the expected mean value of y when all x=0.
Therefore, in the given teacher's equation, the slope is 0.7 and intercept is 37.
Here the intercept means the average score of student who who did not attend her course.
Therefore, the test score that the teacher should expect from a student who did not attend her course is 37.
Because when you multiply the 9 by x you get 9x and when you multiply the 9 by 3 you get 27. So then your final answer would be 9x + 27.

Answer:
It is going 84.12s = 1 minute and 24.12 seconds to fill the tank.
Step-by-step explanation:
The filling time of a gas tank can be given by a first order function in this format:
In which is the current amount of fuel in the tank(in L),
is the volume of the tank(in L),
is the discharge rate of the tank(in L/s) and t is the time in seconds.
Finding the values of the parameters:
The tank is completly empty, so .
The volume of the tank is 14 gallons. However, the problem states that the volume of the tank is measured in liters.
Each gallon has 3.78L.
So
The discharge rate for the gas is 38.0 l/min. However, the problem states that the discharge rate is in L/s. So, to find the value of r, we solve the following rule of three.
38 L - 60s
r L - 1s
Solving the equation:
It is going 84.12s = 1 minute and 24.12 seconds to fill the tank.
