The central angle COA = 2 * angle at the circumference
m < COA = 2 * 80 degrees
Answer: 72
72/8 will get you 9. To see if the answer is correct Multiply 9*8.
According to the empirical rule, the percent of the data points that are below 100 is; 95.44%
<h3>How to use Empirical Rule in Statistics?</h3>
We are given;
Mean; μ = 88
Standard deviation; σ = 6
Sample mean; x' = 100
Formula for z-score is;
z = (x' - μ)/σ
z = (100 - 88)/6
z = 2
Now, from the empirical rule of normal distribution graph attached, we see that at z = 2, the percentage is 95.44%. However, we want to find the percentage that lie below 100. Thus, this is 95.44%
