If the line is linear, a straight line, both should get the same answer. All the points on the line have the same ratio. So when they both solve for the slope, they will get the same answer.
Answer: The will be 1200 miles apart after 2.4 hours.
First draw a picture of an angle of 60 degrees. The vertex is the starting point of the plane and they are flying away from it.
If you drew points for the new positions of the plane and connected them, you would have triangle. The planes are flying at the same speed, so they would be isosceles triangles. And since the vertex angle is 60 degrees, the other angles have to be 60 as well. This makes it an equilateral triangles, meaning all the sides are the same.
So the distance between the planes is equal to the distance that they have flow.
Simply divide 1200 by 500 to get 2.4 hours.
Answer: Choice B) -4
The lower quartile, also known as Q1 or the first quartile, is the left edge of the box. In this case, that is at -4. We can drop a vertical line from the left edge of the box until we hit -4 on the number line.
Side Note: 25% of the data values are below Q1, while 75% of the data values are above Q1
19 is the answer to this question
