answer is because 4×10=40

and 98×4= is 392

40,392

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
