Answer:

8.

Step-by-step explanation:

The mean would be all the marks times the frequencies, then divided by the total of frequencies.

(6 * 5) + (7 * 4) + (8 * 7) + (9 * 10) + (10 * 4) = 30 + 28 + 56 + 90 + 40 = 58 + 146 + 40 = 244.

The total of frequencies are 5 + 4 + 7 + 10 + 4 = 30.

244 / 30 = 122/15 = 8.1333333.

So, the mean is about 8.

Hope this helps!
