A positive negative or no correlation the number of hours a plane in flight in the number of miles flown

Positive correlation

Step-by-step explanation:

Two variables are said to be correlating if they have some kind of relationship - that is, if the value of one variable increases/decreases as the other variable increases or decreases.

More specifically, there are three types of correlation:

- Positive correlation: this occurs if, as the value of one variable increases, the value other variable increases too

- Negative correlation: this occurs if, as the value of one variable increases, the value of the other variable decreases

- No correlation: this occurs if, as the value of one variable increases, the other variable doesn't show any precise trend

In this problem, we are studying the following two variables:

- Number of hours a plane is flying (t)

- Number of miles flown (d)

The two variables are related by the equation

where v is the speed of the plane (in miles per hour).

As we can see from this equation, there is a direct proportionality between the two variables: therefore, as t increases, d increases, and so we can say there is a positive correlation.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

is only a line? i think so
