Jen is interested in examining how having a pet affects sociability among children with Autism Spectrum Disorder (ASD). To collect her data, she sends out an e-mail with a link to an online questionnaire to all parents in Orange County whose children have an ASD. Of these, only 20% of the parents participant in the survey. Why should Jen be concerned with such a low response rate?

a. The small sample size may result in Type I error inflation.
b. Those who did participate are more likely to have bias responses due to social desirability.
c. The results of those who participated may not generalize to all children with ASD.
d. The small sample size increases the likelihood for unreliability of the measure (or instrument).

D

Step-by-step explanation:

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
