Which set of side lengths form a right triangle?

a. 53 m, 48 m, 24 m

b. 8 cm, 17 cm, 14 cm

c. 3 ft, 6 ft, 5 ft

d. 50 in., 48 in., 14 in.

I just took the test and the answer was D

50 in, 48 in, 14 in are the side lengths that form a right triangle

won't that be plagrisim thought?

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;
