Answer:

Solution given:

x. $\:\:\:$ f. $\:\:\:$ fx

13. $\:\:\:$ 15. $\:\:\:$ 195

14. $\:\:\:$ 42 $\:\:\:$ 588

15. $\:\:\:$ x. $\:\:\:$ 15x

16. $\:\:\:$ 10. $\:\:\:$ 160

17. $\:\:\:$ 3. $\:\:\:$ 51

. n=70+x. $\sum$ =994+15x

we have

mean=sum/n

14.44= $\bold{\frac{\sum}{n}}$

14.44= $\bold{\frac{994+15x}{70+x}}$

doing crisscrossed multiplication

(70+x)*14.44=994+15x

1010.8+14.44x=994+15x

15x-14.44x=1010.8-994

0.56x=16.8

x=16.8/0.56

x=30
