Answer:
4.9
Step-by-step explanation:
Let us first find the frequency from the cumulative frequency.
Starting number is same.
To find the next number subtract the previous number from that number.
i.e first number = 0.15
Second number = 0.45 – 0.15 = 0.3
Third number = 0.60 – 0.45 = 0.15
Fourth number = 0.85 – 0.60 = 0.25
Fifth number = 1.00 – 0.85 = 0.15
Value Frequency Value × Frequency
1 0.15 0.15
3 0.3 0.9
5 0.15 0.75
7 0.25 1.75
9 0.15 1.35
Number of frequency = 1
Total value = 0.15 + 0.9 + 0.75 + 1.75 + 1.35 = 4.9
Mean = = 4.9
70,000,000 * 82,445,346
= 5.77117422E+15
That’s what comes out lol
