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

The situation shows neither correlation nor causation
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.

subtract (8x^7-14d) - (-11x^7)
Answer:
19x^7 - 14d
Step-by-step explanation
Step 1:
((8 • (x7)) - 14d) - (0 - 11x7)
Step 2:
(23x7 - 14d) - -11x7
Step 3:
19x7 - 14d
Answer:
19x^7 - 14d
WORKING:
= 8x^7 - 14d + 11x^7
Group like terms
= 8x^7 + 11x^7 - 14d
Add similar elements 8x^7 + 11x^7 = 19x^7
= 19x^7 - 14d
FINAL ANSWER:
19x^7 - 14d

What is the distance between the points (-4, -8) and (10, -8)?
Answer:
14
Step-by-step explanation:
the difference between -4 and 10 is 14, (4 to get to 0, and 10 more to get to 10.) and the difference between -8 and -8 is 0 so we don’t have to count it.

pls help ty
Answer:
2
Step-by-step explanation:
Use BODMAS(bracket, of, division, multiplication, addition and subtraction)
72/8=9
(6*4)=24
24/12+9-9
2+0
=2
The solution for the given operations of numbers is 2.
What is PEMDAS Rule?PEMDAS rule is the same as BODMAS rule.
PEMDAS is the abbreviation for Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.
We are using BODMAS rule here to solve the given operations.
6 * 4 ÷ 12 + 72 ÷8 - 9
According to the rule, first we should do multiplication.
6 × 4 = 24
6 * 4 ÷ 12 + 72 ÷8 - 9 = 24 ÷ 12 + 72 ÷8 - 9
Next do the division.
24 ÷ 12 = 2 and 72 ÷8 = 9
24 ÷ 12 + 72 ÷8 - 9 = 2 + 9 - 9
Now do the addition and subtraction.
2 + 9 - 9 = 2
Hence the final answer for the given operation is 2.

Find the equation of the line shown.
Answer:
[tex]\huge\boxed{y=-\dfrac{1}{4}x+2}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept (0, b)
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex](x_1;\ y_1);\ (x_2;\ y_)[/tex] - points on the line
From the graph we have two points (look at the picture)

Calculate the slope:
[tex]m=\dfrac{2-1}{0-4}=\dfrac{1}{-4}=-\dfrac{1}{4}[/tex]
Put the values of [tex]m[/tex] and [tex]b[/tex] to the equation of a line:

-2(-9x+5)-4x=2(x-5)-4
Simplify your answer as much as possible
Answer:
−2(−9x+5)−4x=2(x−5)−4
Step 1: Simplify both sides of the equation.
−2(−9x+5)−4x=2(x−5)−4
(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)
18x+−10+−4x=2x+−10+−4
(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)
14x+−10=2x+−14
14x−10=2x−14
Step 2: Subtract 2x from both sides.
14x−10−2x=2x−14−2x
12x−10=−14
Step 3: Add 10 to both sides.
12x−10+10=−14+10
12x=−4
Step 4: Divide both sides by 12.

The graph is given below.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 6 is an equation.
We have,
y = 2x + 2
y = x - 2
Now,
The point of intersection.
2x + 2 = x - 2
2x - x = -2 - 2
x = -4
Putting in y = 2x + 2
y = 2 x -4 + 2
y = -8 + 2
y = -6
(-4, -6) is the point of intersection.
Now,
The graph of the equation is given below.
Thus,
The point of intersection between the two equations is (-4, -6).
