Answer:
36.695 approx 36.7
Step-by-step explanation:
find the area of the top triangle and then add it to the area of the bottom rectangle
Area of the triangle: (bh)/2
3.5*4.1=14.35
14.35/2=7.175
Area of the rectangle: bh
4.1*7.2=29.52
Total (add the two values)
29.52+7.175
=36.695
Answer:
The class interval is: 20-30
Step-by-step explanation:
Let l be the lower class limit and u be the upper class limit.
Then according to given statement that class mark is 25

And
Class size is 10
So, the second equation will be:

Adding equation 1 and 2

Now putting u =30 in equation 1

A class interval is written in the form that lower limit comes first and upper limit comes second.
So,
20-30
Hence,
The class interval is: 20-30
