Assume there is a linear relationship between the curb weight of a car (in thousands of kilograms) and its combined mileage (in miles per gallon). the hummer h2 has a weight of 3 thousand kg and mileage of 9 mpg, while a ford taurus sedan weighs 1.9 thousand kg and gets 21 mpg. what is the mileage of a chevy cavalier weighing 1.1 thousand kg?

The mileage of a Chevy Cavalier weighing 1.1 thousand kg is 29.72 mpg.

Step-by-step explanation:

if there is a linear relationship between two variables x and y , then we represent this relation in the form of equation as :   (*)

, where m = rate of change of y with respect to x

c= Constant or the value of y when x=0.

We assume there is a linear relationship between the curb weight of a car (in thousands of kilograms) and its combined mileage (in miles per gallon).

Let y= combined mileage (in miles per gallon)

x= curb weight of a car (in thousands of kilograms)

When x= 3 thousand kg  , y = 9 mpg

⇒                   [Put values in (*)]

⇒

When x= 1.9 thousand kg  , y = 21 mpg

⇒                   [Put values in (*)]

⇒

Eliminate the equation (1) from (2) , we get

Put value of m in (1) , we gte

Substitute the value of m and c in (*) , we get

When x= 1.1

Hence, the mileage of a Chevy Cavalier weighing 1.1 thousand kg is 29.72 mpg.

step-by-step explanation:

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
