Airplane a is flying directly toward the airport which is 20 miles away. the pilot notices airplane b 45 degrees to her right. airplane b is also flying directly to the airport. the pilot of airplane b calculates that airplane a is 50 degrees to his left. based on that information, how far is airplane b from the airport

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

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;
