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.

A 3-yard roll of wrapping paper costs $13.14. What is the price per foot?
Answers
Answer:
Step-by-step explanation:
1 yard is equal to 3 feet.
since you have 3 yards, it'll be 9 feet.
13.14/9 to get your answer
or $1.46 per foot
The price per foot of wrapping paper is $1.46.
First, we need to convert 3 yards to feet. There are 3 feet in 1 yard, so 3 yards is equal to 3 * 3 = 9 feet.
The price per foot is simply the total price divided by the number of feet. In this case, the total price is $13.14 and the number of feet is 9, so the price per foot is:
price per foot = $13.14 / 9 feet
= $1.46 per foot
Therefore, the price per foot of wrapping paper is $1.46.

Katniss Everdeen found the absolute value of |25| to be -25.
Do you agree? Yes or No
Explain:
Answers
Answer:
No
Step-by-step explanation:
Absolute values will never be negative.
Since absolute values are simply the number's distance from zero, it can never be negative, since there are no negative distances.
In this case, | 25 | is equal to 25. This is because the distance from 0 to 25 is 25.
So, Katniss is wrong.

A package that is heavier than 11 lb. and 8 oz. will have a label that says "heavy" on it. Gloria packed 6 flower pots to send to her customers. Each of the flower pots weighs 1 lb. and 12 oz. The packing material weighs 5 oz. Will her package be labeled as "heavy"?
Answers
Answer:
No, the package will not be labeled "heavy"
Step-by-step explanation:
1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).
2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.
3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.
4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.
Final) so in the end, you would have 10lb. 13oz.
