Asurvey was given to 50 people to determine if they prefer white or brown rice at a local chinese restaurant. given the following reasons, determine which fulfills one of the requirements for a binomial distribution.

a. the study has a finite number of trials.
b. the study is conducted randomly.
c. the survey focuses on food only from one restaurant.
d. the study is conducted locally.

a. the study has a finite number of trials.

Step-by-step explanation:

A binomial experiment is an experiment which satisfies the following four conditions:

Hence, option a. "the study has a finite number of trials." is one of the requirements for a binomial distribution.

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
