Slope (or gradient) is used to determine if lines are parallel, as parallel lines share the same gradient.

The gradient is used to determine whether they intersect, as you'll have to plug x and y values in to both of the line's equations, which involves having the line's gradients.

The gradient is used to see if points are collinear, as you need to determine whether the gradient between two points is equal to the gradient of another 2 points, and if so, the points are collinear.

Finally, the gradient is used to find the equation of the line, as we require to plug in the gradient in to equations such as (y - y1 = m(x - x1)) in order to find the equation of the line.

Answer:

<h2>The mean decreases, and the median remains the same.</h2>

Step-by-step explanation:

Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.

In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.

Now, the range of the data set decreases from 7 to 3.

On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.

Therefore, the right answer is <em>The mean decreases, and the median remains the same.</em>

Which relation is also a function?

slavikrds [6]

Answer:

Hi san, A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. For example, consider the following sets X and Y.
