Answer:

The radius is <u>63.69</u>.

Step-by-step explanation:

Given:

The circumference of a circular track is 400.

Now, to find the radius:

So, to get the radius(r) we put the formula of circumference:

Circumference=2\pi r

⇒ 400=2\times 3.14\times r

⇒ 400=6.28\times r

<em>Dividing both sides by 6.28 we get:</em>

⇒ 63.69=r

⇒ r=63.69

Therefore, the radius is 63.69.

Which relationships could have a negative correlation? Select three options.
Rudik [331]

The relationships that could have a negative correlation are as follows:

  • the speed of a train and the length of time to reach the destination
  • number of hours worked and free time
  • speed of a car and minimum stopping distance

<h3>What is negative correlation?</h3>

Correlation between two variables shows the relationship between the two variables.

A positive correlation means that both variables move in the same direction i.e. as one increases, the other increases.

However, a negative correlation means that both variables are inversely related i.e. one increases as the other decreases.

Therefore, the relationships that could have a negative correlation i.e. inversely related are as follows:

  1. the speed of a train and the length of time to reach the destination
  2. number of hours worked and free time
  3. speed of a car and minimum stopping distance
