5.6 is the decimal form equivalent & 5 6/10 & 5 3/5 are equivalent fractions.
First change the 4
to 4
.
Then multiply 4
and 3

in².
Answer:
10.5
Step-by-step explanation:
Given the data:
Age. l frequency
1-5. l 3
6-10. l 3
11-15. l 3
16-20. I 3
Mean :
Σfx / Σf
Obtain the midpoint (x) = (upper + lower boundary) / 2
Hence, midpoint x :
Age. l frequency | x
1-5. l 3 | 3
6-10. l 3 | 8
11-15. l 3 | 13
16-20. I 3 | 18
Σfx = (3*3) + (3*8) + (3*13) + (3*18) = 126
Σf = (3 + 3 + 3 + 3) = 12
Mean = Σfx / Σf = 126 / 12 = 10.5
I believe that the answer is 6. Feel free to check yourself but i think its 6
