A study was conducted to determine whether exercise or dietary supplements would slow bone loss in older women. An investigator measured the mineral content of bones by photon absorptiometry. A total of 6 measurements (3 on dominant side and 3 on nondominant side) were made on each subject at the beginning of the study. The researcher then assigned the subjects to the two treatments and conducted the experiment. When it was time to conduct the analysis the researcher decided to check on whether there was a difference in bone mineral content prior to assignment to a group. What type of test would be used to check for a difference?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
