The area of an airplane's wings is related to the airplane's lifting force, which holds the
airplane in the air. the table below lists several wing areas and the corresponding
lifting forces.

the ratio of lifting force to area is equivalent for all pairs in the table. what are the
values of x and y?
a x = 375 square feet and y = 7,500 pounds
b x = 335 square feet and y = 7,500 pounds
c x = 375 square feet and y = 6,300 pounds
d x = 335 square feet and y = 6,300 pounds

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;

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
