Answer:

51.3

Step-by-step explanation:

20-30: 100

30-40: 220-100 = 120

40-50: 350-220 = 130

50-60: 750-350 = 400

60-70: 950-750 = 200

70-80: 1000-950 = 50

Mean = sum(f × x) / sum(f)

= [25×100 + 35×120 + 45×130 + 55×400 + 65×200 + 75×50] ÷ 1000

= 51,300 ÷ 1000

= 51.3

**Answer: The answer would be 8. **

**Step-by-step explanation: I'm going to assume you mean 7 8/13 is a mixed fraction. So you multiply the denominator, 13, multiply 7 to that, then add 8 to it and the denominator would be the same as before. That should give you 99/13. When you divide, you get around 7.6, rounding closest to 8. **
