Here is what your frequency/cumulative frequency table would look like. The cumulative frequency is where you add all the frequencies from before it to get a sum after each interval.
<u> Frequency </u> <u>Cumulative Frequency</u>
0-25 8 8
26-50 0 8
51-75 4 12
76-100 2 14
Answer:
50.24
Step-by-step explanation:
Area = r^2 x 3.14 (pi)
Radius = 8 ÷ 2 = 4
4² = 16
16 x 3.14 = 50.24
Area = 50.24 cm ²
400/1600 =25%
Explanation:
Total=1,200+400=1,600
