Anew brand of gym shoe claims to add up to 2 inches to an athlete’s vertical leaps. design an experiment to test this claim. determine the experimental and control groups.

a. experimental group: athletes wearing the new shoes; control group: non-athletes wearing the new shoes

b. experimental group: athletes wearing the new shoes; control group: athletes not wearing the new shoes

c. experimental group: athletes wearing the new shoes; control group: non-athletes not wearing the new shoes

d. experimental group: athletes not wearing the new shoes; control group: athletes wearing the new shoes

B. experimental group: athletes wearing the new shoes; control group: athletes not wearing the new shoes.

Explanation:

The objective of the experiment is to determine whether the new brand of gym shoes increase athlete's vertical leaps.

Then, your experiment shall have:

The independent variable, i.e. a variable that you can manipulate and test to determine how it changes the dependent variable. In this case it is the shoes.The dependent variable is how high the athletes jump.Control group: the group with which you want to compare to determine whether it is true or not that the new brand of gym shoe increase athlete's vertical leaps.

Then, you can test the two groups.

The experimental group, which is the athletes wearing the new shoes, andThe control group, which is the athletes not wearing the new shoes.

That is described by the statement B. experimental group: athletes wearing the new shoes; control group: athletes not wearing the new shoes.

Note that, in order for the results not be biased, the two groups should be selected randomly and represent average athletes. It is not correct to select elite athletes or non average athletes for either of the groups.

Then, you will compare the marks of the two groups and, if the difference in the heights of the jumps is significatively in favor of the new shoes, you can back up the claim of the new brand of gym shoes.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
