Answer:
To find the range of scores for all the students in both classes, you need to consider the lowest and highest scores across both Class A and Class B.
For Class A:
- Lowest score = 39
The range for Class A is given as 57.
So, the highest score in Class A can be calculated as:
Highest score in Class A = Lowest score in Class A + Range of scores for Class A
Highest score in Class A = 39 + 57
Highest score in Class A = 96
For Class B:
- Lowest score = 33
The range for Class B is given as 60.
So, the highest score in Class B can be calculated as:
Highest score in Class B = Lowest score in Class B + Range of scores for Class B
Highest score in Class B = 33 + 60
Highest score in Class B = 93
Now, to find the range of scores for all the students in both classes, you need to find the lowest and highest scores from both Class A and Class B:
Lowest score overall = minimum(Lowest score in Class A, Lowest score in Class B)
Lowest score overall = minimum(39, 33) = 33
Highest score overall = maximum(Highest score in Class A, Highest score in Class B)
Highest score overall = maximum(96, 93) = 96
Now, you can calculate the range of scores for all the students in both classes:
Range of scores for all students = Highest score overall - Lowest score overall
Range of scores for all students = 96 - 33
Range of scores for all students = 63
So, the range of scores for all the students in both Class A and Class B is 63.
