A scuba instructor wants to know the opinions of scuba divers about online scuba diving tests. She obtains a list of 900 scuba divers who have completed an online scuba diving course recently and e-mails a questionnaire to a randomly selected group of 175 of these divers. Only 54 of the questionnaires are returned. Identify the population and the sample in this study. (4 points) The population is 175 and the sample is 54.

The population is 900 and the sample is 175.

The population is 900 and the sample is 54.

The population is 54 and the sample is 900.

The population is 175 and the sample is 900.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

answer: 4 (:

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
