the first number must be between 1 and 10 (here is 3.3)
the power (here is 5) is an integer exponent of 10 that indicates how many places the decimal point must be moved to make equation true

Answer:
The 95% confidence interval of the proportion of Americans who believe in the conspiracy is
Step-by-step explanation:
From the question we are told that
The sample size is n =1057
The number that believe there was a conspiracy is k = 614
Generally the sample proportion is mathematically represented as
![\^ p = \frac{614}{1057 }](https://tex.z-dn.net/?f=%5C%5E%20p%20%3D%20%20%5Cfrac%7B614%7D%7B1057%20%7D)
=> ![\^ p = 0.5809](https://tex.z-dn.net/?f=%5C%5E%20p%20%3D%200.5809)
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence interval is mathematically represented as

Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)
radius=6
