A student organization wondered how many hours per week college students study during a term. Each of the 10 students in the organization asked 10 of their friends how much they typically studied each week. A​ 95% confidence interval for the mean number of hours studied per week was​ (18,30). Are the conditions satisfied to use the confidence interval to make an inference to the population of​ interest?

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
