Amanda is studying relationships between the values and ages of different items. She decides to ask teachers at her school to estimate the values and ages of their cars. She will exclude any antique cars and knows that the value of a car depreciates over time. Which correlation is expected between the age and value of a car?
A. positive
B. negative
C. constant
D. none
Answers
Answer: c- negative
Step-by-step explanation:
As the car ages, it's performance decreases owing to depreciation of its parts.
Hence, it's value decreases.
Age of the car is inversely proportional to it's value.
Answer:
The correlation between the value and age of the car is negative.
Option = > B
Explanation:
This means that as one increase and the rest all are decreases.
Negative correlation is a type of relationship on variables wherein one increases and the other decreases.
= > It is true that the value of the car depreciates over time.
Hence, as the car becomes older.
(Also since new cars are being made available)
It's price decreases so that these cars can be bought by people who has the amount of money for that car.
Did You know?
On a graph, this situaton will look like a line going down from the top left to the bottom right.
A constant correlation means that something is increasing or decreasing at a steady rate.
(Since, we don't know how much a car's value depreciates each year).
(We can't determine if it's a constant relationship).
Hence,
The correlation between the value and age of the car is negative.
Option = > B
