Approximately 9 out of every 50 people who saw a movie this week say they watched it on Netflix. Suppose we want to find the probability that a randomly selected movie-goer saw a movie on Netflix this weekend. Express that probability in three ways: As a fraction, a proportion, and a percentage.

Explanation:

1. As a fraction:

Depart from the definition of probability: probability is the number of favoragle outcomes divided by the total number of possible outcomes:

2. As a proportion:

A proportion is the equality of two ratios. In this case you must set the ratio of people who say they watched it on Netflx, x, per every people who saw a movie this week, 1, equal to the ration 9 /50.

Hence, the proportion that shows the probability is:

Where x is the probability.

3. As a percentage

You just have to multiply the probability by 100:

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

the answer is c)8
