Answer 1

Answer: 24

Step-by-step explanation:

i'm not too sure as there is not enough information but i think you add the numbers togethers and divide by 2 to get the middle (24)

Answer 2

The class mark of the class interval 22.5 to 25.5 is 24.

Class mark is defined as the mid-point of the given class. It is calculated as the sum of the upper limit and lower limit of the class, divided by 2.

Class mark = $\frac{Upper limit + lower limit}{2}$

Here, upper limit = 25.5 and lower limit = 22.5

Therefore, class mark = (25.5 + 22.5)/2  , or, 48/2

∴ Class mark = 24
