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.
Answer:
x=12.
Step-by-step explanation:
Let's get this straight out of the way, the 3 angles of a triangle ALWAYS add up to 180. Now that that's said, lets begin. Since the opposing side of an angle is the same as the regular side, we simplify to get: 5x+120=180. 180-120=60. so 5x=60. 60/5=12. so x=12.
<h3>Answer:</h3>
room 3 or 4
<h3>Explanation:</h3>
We assume the inequalities tell the rooms that were checked and found empty.
The solution to 3) is ...
... 2x + 3 > 11
... 2x > 8 . . . . . subtract 3
... x > 4 . . . . . . .divide by 2
The solution to 4) is ...
... -3x > -9
... x < 3 . . . . . . divide by -3
Thus, rooms greater than 4 and less than 3 were found empty. Rooms 3 and 4 were not checked, so either one could hold Nessie.
_____
The other inequalities have solutions that are already covered by the solutions to these.
1) x < -1 . . . . after subtacting 4
2) x > 5 . . . . after multiplying by 5
Based from background knowledge, I believe that the correct answer among all of the given choices would be B.) 38/2. This would give you 19. If I am mistaken, please correct me. But I am definitely positive that this is the right answer.
I hope this is the answer you were looking for and that it helps!! :)
To solve this we are going to use the free distance fallen formula:
where
is the distance
is the gravity of Earth
is the time in seconds
We know from our problem that the
penny fell off the top of the building and hit the sidewalk below 3.1 seconds later, so
. Lets replace the value in our formula:
meters
We can conclude that the penny fell a distance of 47.098 meters
