Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.
Explanation:
In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.
It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.
For the other options:
- <u><em>The amount of noise</em></u><em>. This can modified by the use or not of headphones and is the independent variable, subject to modification.</em>
- <u><em>The type of music the employees listen to while they work</em></u><em>. Does not represent dependent or independent variable.</em>
- <u><em>The amount of training employees need</em></u><em>. It is not the variable being studied.</em>
Yes it is true because after many years of water or wind eroding away at the rock will cause it to break up into tiny pieces
Hey :) hope your day is going well. :P I listed some information below, that may or may not help!
<em>"Evaluate the following statements. volcanoes are only found along coastlines."</em>
<u><em>False!</em></u>
<em><u>Most are found along plate boundaries and hot-spots. :) </u></em>
They are found along plate boundaries because when the plate's collide together, <u>they may leave cracks</u> behind and may turn later into small hills and eventually grow even larger as time goes, and <u>produce magma from under the earth's layers</u>.
Hope this helped you, and as always remember if you need any more help, mssg me and i'll answer any questions you may have. <u>Have a great day. :)</u>
