5. Justin usually blows his nose using Kleenex tissues. His snot keeps leaking through the tissue. He decided he's going to create and experiment to find out if there is something better. What is 1 constant?
a. type of tissue
b. Justin
c. amount of tissue
d. mass of snot the tissues can hold
e. kleenex
7. Justin usually blows his nose using Kleenex tissues. His snot keeps leaking through the tissue. He decided he's going to create and experiment to find out if there is something better. What is the dependent variable?
a. kleenex
b. Justin
c. type of tissue
d. mass of snot the tissues can hold <NOT THIS>
e. amount of tissue
8. Mrs. McNiece wanted to see how different types of music affected students' pulse rates. She played different types of music: heavy metal, rap, R&b, alternative, pop, country, and classical music. What is the dependent variable?
a. classical music resulted in the highest pulse rate <NOT THIS?>
b. high pulse rate
c. Mrs. McNiece
d. pulse rate <NOT THIS>
e. types of music
same Justin the whole tie
amount of tissue needed depends on type of tissue used
pulse rate is the dependent variable and I do not know why you say it is not
write as:
pulse rate = f(music type)

5. To identify the constant in Justin's experiment, we need to determine the factor that will remain the same throughout all his tests. A constant is a variable that is not changed or tested during an experiment, but rather remains consistent. In this case, the constant is the factor that Justin will keep the same across all his experiments.
In the given options (a. type of tissue, b. Justin, c. amount of tissue, d. mass of snot the tissues can hold, e. Kleenex), the most appropriate constant is (a. type of tissue). Justin wants to compare different types of tissues, so he will vary the type of tissue he uses while keeping other factors consistent.
7. The dependent variable in an experiment is the variable that is measured or observed as a result of the changes made to the independent variable. In Justin's experiment, he wants to find out if there is something better than Kleenex tissues for blowing his nose, so he will be testing different variables to measure their effectiveness.
Out of the provided options (a. Kleenex, b. Justin, c. type of tissue, d. mass of snot the tissues can hold, e. amount of tissue), the dependent variable would be (e. amount of tissue). Justin will be measuring the amount of snot that leaks through the tissue to determine whether the alternative option is better or worse than Kleenex.
8. In Mrs. McNiece's experiment on how different types of music affect students' pulse rates, the dependent variable is the variable that is being measured as a result of playing different types of music.
Among the given options (a. classical music resulted in the highest pulse rate, b. high pulse rate, c. Mrs. McNiece, d. pulse rate, e. types of music), the dependent variable would be (d. pulse rate). Mrs. McNiece is trying to see how different types of music affect the students' pulse rates, so the pulse rate is what she is measuring or observing as the outcome of the experiment.
5. The constant in Justin's experiment is a. type of tissue.
7. The dependent variable in Justin's experiment is e. amount of tissue.
8. The dependent variable in Mrs. McNiece's experiment is d. pulse rate.
