Variable 10 20 30 40 50 60 70 80
frequency 4 2 1 f 0 3 5 8
8​

Answer 1

Step-by-step explanation:

40f+50(0)=48 (given)

40f+0=48

40f=48

f=48/40

f=6/5

f=1.2

Answer 2

Answer:

f= 22+f

Step-by-step explanation:

fixi =

40

40

30

40f

0

180

350

640

all added= 1280+40f

formula = fixi/xi=48

1280+40f/22+f=48

F=28
