The film society is trying to decide what type of film to show for the senior class movie night. The preferences of a small survey of 20 students are given in the following graph.
If there are 452 students in the senior class, what would be a good prediction of how many would prefer an action film?
113
68
90
1,808
To find a good prediction of how many students would prefer an action film, we can use the proportion from the survey and apply it to the total number of students.
In the survey, 20 students were asked about their preferences, and the graph shows that 68 students preferred action films.
Therefore, we can set up a proportion: 20/68 = 452/x
Cross-multiplying, we get 20x = 68 * 452
Simplifying, we find that 20x = 30,736
Dividing both sides of the equation by 20, we get: x = 1,536
Thus, a good prediction of how many students would prefer an action film would be 1,536.
Therefore, the answer is 1,536.
To predict how many students would prefer an action film, we can use the information from the given graph. Looking at the graph, we see that 68 students out of 20 prefer an action film.
To find the prediction for the entire senior class, we can set up a proportion:
68/20 = x/452
Cross-multiplying, we get:
20x = 68 * 452
Simplifying, we have:
20x = 30,736
Dividing both sides by 20, we find:
x = 1,536.8
Therefore, a good prediction of how many students would prefer an action film is 1,537.
To find a good prediction of how many students would prefer an action film, we can use the percentage of students from the survey who preferred an action film.
From the graph, we can see that out of 20 students surveyed, 4 preferred action films. To find the percentage, we divide 4 by 20 and then multiply by 100:
(4/20) * 100 = 20%
Now that we know 20% of the surveyed students prefer action films, we can make a prediction for the entire senior class of 452 students.
To find the prediction, we multiply the percentage (20%) by the total number of students (452):
(20/100) * 452 = 90
Therefore, a good prediction is that approximately 90 students would prefer an action film for the senior class movie night.
So the answer is 90.
