Answer 1

Answer:

16. 21

17. 10

18. 45

19. 40

20. 50

Step-by-step explanation:

16. Number of people who attended the mela who are above the age of 40 = frequency of class 40-50 + frequency of class 50-60 = 14 + 7 = 21

17. Class size = Upper limit - Lower limit

You can take any class and verify that the class size is 10. For example, for the class 30-40, the class size is 40 - 30 = 10.

18. Class mark = $\frac{1}{2}$(Upper limit + Lower limit) = $\frac{1}{2}$(40 + 50) = 45

19. The ending number of the class is the upper limit. The class 30-40 ends at 40, which is the upper limit.

20. The beginning number of the class is the lower limit. The class 50-60 begins at 50, which is the lower limit,
