Martin is interested in the new hypermiling movement which focuses on getting the best miles per gallon (MPG) when driving. He gathered
some data about the weights, in thousands of pounds, of different cars and their average MPG. The graph below shows the results of Martin's
research

The situation shows neither correlation nor causation
Answers
Answer:
The correct option is;
The situation shows correlation without causation
Step-by-step explanation:
The given data are;
Weight y [tex]{}[/tex] Miles Per Gallon
42 [tex]{}[/tex] 18
36 [tex]{}[/tex] 12
30 [tex]{}[/tex] 6
. [tex]{}[/tex] x
24 [tex]{}[/tex] 0
The first difference of the data = 42 - 36 = 36 - 30 = 30 - 24 = 6
18 - 12 = 12 - 6 = 6 - 0 = 6
The first difference of the data is constant and equal to 6
Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;
The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;
(42 - 24)/(18 - 0) = 1
Therefore, the points of the data fit into the straight line and the data of the situation shows correlation
In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.
Answer:
The situation shows correlation with causation.
Step-by-step explanation:
A correlation between two variables is a measure of the strength of the association between them.
It can be seen from the scatter plot that as the weight of the car increases, the miles per gallon decreases.
Causation between variables indicates that one of the variables causes the other variable to occur. Causation between variables always implies correlation.
The weight of the car affects the miles per gallon because cars that weigh more require more power to move. Hence, heavier cars get lower miles per gallon of fuel.
Therefore, the situation shows correlation with causation.

Answers
Answer:
59 degrees
Step-by-step explanation:
All the angles of a triangle (when combined) result in 180 degrees. This means that:
Angle 1 + angle 2 + angle 3 = 180 degrees.
We can see here that the shape here is a right triangle (noted by the square in the corner). This means that the angle set with the square is equal to 90. With this, we already have two of our angles! All we need is to set the equation using w, the angle you'll want to find:
31 + 90 + w = 180
w = 59
And there you are! Make sure to practice a few more problems like these to really get the hang of it. Good luck!
Which equation is equivalent to y-6= -12(x + 4)?
Answers
Answer:
y=-12x-42
Step-by-step explanation:
y-6=-12(x+4)
y= -12(x+4)+6
y=-12x-48+6
y=-2x-42
To solve the equation x - 4 = 12,
A) Add 4 to both sides
B) subtract 4 from both sides.
C) add 4 to the left and subtract from the right.

With displacement, all we care about is the beginning and end. We don't care about the middle part(s) of the journey. So we'll take the straight line route from beginning to end when it comes to computing displacement.
We start at A(0,0) and end at B(-2,0). Going from A directly to B has us go 2 km west. Keep in mind that displacement is a vector, so you must include the direction along with the distance.
