Answer:
Relative frequency
0.214
0.268
0.446
0.071
Total 1
Step-by-step explanation:
The relative frequency is computed by dividing the individual frequencies to the sum of frequencies.
sum of frequencies=12+15+25+4=56
Class Relative Frequency
10-20 12/56=0.214
20-30 15/56=0.268
30-40 25/56=0.446
40-50 4/56=0.071
Total 12/56+15/56+25/56+4/56=56/56=1
The equation in the form of the given expression is (0)² + (1)² = 1
<h3>Trigonometry identity</h3>
According to some of the trigonometry identity
sin 0 = 0
cos 0 1
Given the expression below
sin^2 0+cos^2 0=1
This can also be expressed as:
(sin0)² + (cos0)² = 1
Substitute
(0)² + (1)² = 1
Hence the equation in the form of the given expression is (0)² + (1)² = 1
