Total of all frequencies:
5+8+1213+11= 49
Divide the frequency of 59-61 by total frequencies:
13/49 = 0.265 which rounds to 0.27
The answer is 0.27
Answer:
x=11
Step-by-step explanation:
the question would be to find x
3x + 28 + 5x + 52 + 2x - 10=180 (sum of angles in a triangle is equal to 180⁰)
10x + 70=180
10x=180-70
10x=110
x=110/10
