Answer: 5x-7
Step-by-step explanation:
Relative frequency is the absolute frequency (i.e. the number of times of the wanted result) divided by the total number of events.
In this case you have to calculate: the number of heads that came up divided by the number of times the coin was flipped.
Number of times the coin was flipped: 20
Numbef of times head came up: 7
Relative frequency: 7 / 20 = 0.35, which is the option B.
88/8 =11
Unique key in 1 octave = 12
so, in 11 octave, 12*11 = 132
The answer is 61.92 all u do is 3 x 20.64
