What is the upper class limit for the class 35 45?

Answer. The upper class limit of class interval 35-45 is equal to c) 45.

How do you find the upper class limit?

To find the upper limit of the first class, subtract one from the lower limit of the second class. Then continue to add the class width to this upper limit to find the rest of the upper limits. Find the boundaries by subtracting 0.5 units from the lower limits and adding 0.5 units from the upper limits.

What is the class mark of 90 120?

105Complete step by step answer: The minimum value in a class is its lower limit and the maximum value in a class is the upper limit. The given class is 90-120. So, the lower limit of this class is 90 and the upper limit is 120. Hence, the class mark of the class 90-120 is 105.
