a teacher put all her students quiz scores up on the representation below. quiz scores how many students are in the class?
Answer
Explanation:
Step1: Identify the frequency for each score range.
Read the height of each bar from the histogram, which represents the number of students (Frequency) in that score range:
- 40-49: 6 students
- 50-59: 2 students
- 60-69: 3 students
- 70-79: 2 students
- 80-89: 5 students
- 90-99: 7 students
Step2: Sum the frequencies to find the total number of students.
Add the number of students from all score ranges. $$ \text{Total Students} = 6 + 2 + 3 + 2 + 5 + 7 $$ $$ \text{Total Students} = 25 $$
Answer:
There are 25 students in the class.
