Answer:
a = 0.6; b = 0.4; c = 0.2; d = 0.8
Step-by-step explanation:
The value of a represents the 180 out of 300 in the first row. 180/300 = 0.6.
The value of b represents the 120 out of 300 in the first row. 120/300 = 0.4.
The value of c represents the 40 out of 200 in the second row. 40/200 = 0.2.
The value of d represents the 160 out of 200 in the second row. 160/200 = 0.8.
The values of a, b, c, and d are 0.6, 0.4, 0.2, and 0.8 respectively.
It is defined as the number of waves that crosses a fixed point in one second known as frequency. The unit of frequency is per second.
On comparing the two tables given:
We can calculate the value of 'a' as:
180 out of 300 ie.
a = 180/300 ⇒ 0.6
Similarly for 'b' 120 out of 300
b = 120/300 ⇒ 0.4
For 'c' 40 out of 200
c = 40/200 ⇒ 0.2
For 'd' 160 out of 200
d = 160/200 ⇒ 0.8
Thus, the values of a, b, c, and d are 0.6, 0.4, 0.2, and 0.8 respectively.
