The center of an airplane propeller is 13 feet off the ground and the radius of the propeller is 3 feet. The B blades of the propeller are set at pi/6, 5pi/6, and 3pi/2 radians from 0 radians directly to the right of the center of the propeller. What is the height of the the tip of each propeller in this situation

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
