Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
<h3>
</h3>
where
m is the slope
( x1 , y1) is the point
From the question the point is (0 , 3) and slope is - 6
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>

1) The population
Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.
2) The sample is every set of five cards that is selected by each student.
3) I think the sample is representative because all ther terms have the same probability of being selected.
Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.

Answer: 27 rows contain 25 vines.
Step-by-step explanation:
Let x represent the number of rows that contain 20 vines.
Let y represent the number of rows that contain 25 vines.
Sarah plants 760 vines in rows containing either 20 vines or 25 vines. This means that
20x + 25y = 760- - - - - - - - - - -1
There are 3 times as many rows containing 25 vines as there are rows containing 20 vines. This means that
y = 3x
Substituting y = 3x into equation 1, it becomes
20x + 25 × 3x = 760
20x + 75x = 760
95x = 760
x = 760/95
x = 9
y = 3x = 3 × 9
y = 27
