Answer:
50% pen first box and 62.5% crayon from second box
Step-by-step explanation:
The first box contains 4 items, 2 of each. This means there are 
pens. This gives you a chance of picking out a pen. This can be written as 50%.
The second box contains 8 items, 3 color pencils and 5 crayons. This means 
of the contents are crayons, meaning you have a or 62.5% chance of picking a crayon.
*For working out the percentages, you should convert the fraction to a decimal and then multiply that by 100.
**This content involves fractions, decimals and percentages, as well as basic probability, which you may want to revise. I'm always happy to help!
Answer:x times 1.5 = y
Step-by-step explanation:
Answer:
The options are absent, but the dependent variable in this experimental setup is the test scores from both groups of the experiment.
Step-by-step explanation:
The dependent variable, just like the name suggests, is the variable whose value or outcome depends on the some other variable(s) in an experimental setup.
For this research study, the aim is to evaluate the effect of a silent studying environment or listening to classical music while studying on the academic performance of students as reflected in their test scores.
So, for each of the two groups in this experimental setup, the test scores of the students should depend directly on the the effects of either of the two conditions mentioned earlier. Hence, it is evident that the test scores of students is the undisputed dependent variable for this experimental setup.
Hope this Helps!!!
