Answer:
Option 4: 1.25/2π = 32/2πr
Step-by-step explanation:
Arc length = (theta/2pi) × 2pi × r
32 = (1.25/2pi) × 2pi × r
1.25/2pi = 32/(2pi × r)

Answer: 
Step-by-step explanation:
According to the empirical rule, the 95% confidence interval for the true population proportion is given by :-

Given : . The survey resulted in a sample proportion of p′=0.14, with a sampling standard deviation of σp′=0.02, who preferred reading an e-book.
Then, the 95% confidence interval for the true proportion of adults who prefer e-books will be :-

Hence, the 95% confidence interval for the true proportion of adults who prefer e-books=
