caelyn wanted to find out what shampoo made her hair the shiniest . everyday she washed her hair with different shampoos and then rated how shiny her hair was, on a scale from 1-10. she used pantene, herbal essences, l’oreal, and just water.
independent variable:
dependent variable:
control:
constant:

The correct answer will be option-

1. Independent Variable: brands of shampoo

2. Dependent Variable: shining of the hair

3. Control: sample without any treatment of shampoo.

4. Constant: amount of water and the shampoo

Step-by-step explanation:

In a scientific experiment, three important types of  variables are studied which are:

1. Dependent Variable: The variable which has to be studied in the experiment which in the given question is the shining of the hair

2. Independent Variable: the variable which when modified control and influences the dependent variable which is brands of shampoo

3. Constant: The variable which remains same or constant throughout the experiment which is the amount of water and the shampoo

Also, the samples of an experiment are divided into two groups:

1. Experimental group: samples in which the variable to be studied is included

2. Control group: the group in which the key variable is not present and thus acts as a reference to the experimental group like the sample without any treatment of shampoo.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
