Anissa asked a group of students to choose their favorite type of lunch from the choices of pizza, burger, and sandwich. The results of the survey are shown on the graph.
Based on the graph, how many students in a class of 360 students would be expected to choose pizza or sandwich as their favorite type of lunch?
Responses
A 7070
B 280280
C 200200
D 340340
To find the number of students in a class of 360 students who would be expected to choose pizza or sandwich as their favorite type of lunch, we need to find the total percentage of students who prefer pizza or sandwich from the graph.
According to the graph, 13% of students prefer pizza and 13% prefer sandwich. Therefore, the total percentage of students who prefer pizza or sandwich is 13% + 13% = 26%.
To find the number of students, we multiply the total percentage (26%) by the total number of students in the class (360):
26% of 360 = (26/100) * 360 = 0.26 * 360 = 93.6
Therefore, we would expect approximately 93.6 students in a class of 360 students to choose pizza or sandwich as their favorite type of lunch.
Since we can't have fractional students, we round the number to the nearest whole number:
Approximately 94 students in a class of 360 students would be expected to choose pizza or sandwich as their favorite type of lunch.
None of the given answer choices match our calculation.
To determine how many students in a class of 360 students would be expected to choose pizza or sandwich as their favorite type of lunch, we need to find the sum of the number of students who chose pizza and sandwich from the graph.
From the graph:
- The number of students who chose pizza is 13% of 360, which is 0.13 * 360 = 46.8.
- The number of students who chose sandwich is 33% of 360, which is 0.33 * 360 = 118.8.
Therefore, the sum of the number of students who chose pizza and sandwich is 46.8 + 118.8 = 165.6.
Therefore, the expected number of students in a class of 360 students who would choose pizza or sandwich as their favorite type of lunch is 165.6.
None of the given options, A, B, C, or D, match this result. Please double-check the options.
To find the number of students in a class of 360 who would be expected to choose pizza or sandwich as their favorite type of lunch, we need to analyze the graph.
The graph represents the results of a survey where students were asked to choose their favorite type of lunch from the options of pizza, burger, and sandwich. However, the graph is not provided in the question.
If you have access to the graph, you can look at the bars representing the number of students who chose pizza and sandwich as their favorites. Add the values of those bars together since we want to know the sum of students who chose either pizza or sandwich. This sum will give you the number of students in the survey who chose either pizza or sandwich.
Then, you can use the ratio of the number of students who chose either pizza or sandwich to the total number of students in the survey to estimate the number of students in a class of 360 who would make the same choice.
For example, if the graph shows that 13 students chose pizza and 33 students chose sandwich, the total number of students who chose either pizza or sandwich would be 13 + 33 = 46. Suppose that this survey was conducted among 1313 students. The ratio of students who chose either option to the total number of students in the survey would be 46/1313.
To find the estimated number of students in a class of 360 who would choose either pizza or sandwich, you can multiply the ratio by the total number of students in the class:
(46/1313) x 360 = 12.64
Therefore, the estimated number of students in a class of 360 who would be expected to choose pizza or sandwich as their favorite type of lunch is approximately 12 students.
Please note that the specific values from the graph were not provided in the question, so you may need to refer to the actual graph to get accurate results.
