Which of these pairs of variables would you expect to be represented by a scatterplot with a negative correlation? a. the weight of a package and the cost to mail the package b. the amount of gas in the tank of a car and the number of miles driven c. the cost of a car and the number of tires it has d. the cost a telephone call and the length of the call

B) the amount of gas in the tank of a car and the number of miles driven

Step-by-step explanation:

A negative correlation means that as the independent variable (x) increases, the dependent variable (y) decreases.

The way this problem situation is worded, the amount of gas in the car would be independent and the number of miles driven is the y.  This means the number of miles that have been driven depends on how much gas is left in the car.

As the amount of gas remaining in the car increases, the number of miles that have been driven will decrease; this is because if you haven't used much gas, you haven't driven many miles.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
