3 0

The variable the researchers intentionally varied in the experiment is time and the units of the variable is mins.

<h3>What is an independent variable?</h3>

The independent variable is the variable that the researcher varies or changes or manipulates in the course of the experiment. The independent variable usually have a direct effect on the dependent variable.

With the passage of time, the level of concentration increases. This means that time is the independent variable and concentration is the dependent variable.

What do you recall about transformations in a plane? What is important to remember about transformations? What's the difference

Butoxors [25]

Answer:

Any image in a plane could be altered by using different operations, or transformations. Here are the most common types:

Translation is when we slide a figure in any direction.

Reflection is when we flip a figure over a line.

Rotation is when we rotate a figure a certain degree around a point.

Dilation is when we enlarge or reduce a figure.

Transformations map one set of points onto another set of points, generally with the purpose of changing the position, size, and/or shape of the figure made up by the first set of points. The first set of points, from the domain of the transformation, is called the set of pre-images, whereas the second set of points, from the range of the transformation, is called the set of images. Therefore, a transformation maps each pre-image point to its image point.
