WILL MARK BRAINLIST FOR CORRECT ANSWER! Square ABCD has sides of length 15 ft. If the remaining part of the shape is a semicircle, what is the perimeter around the entire shape, to the nearest hundredth?

A) 53.41 ft
B) 58.27 ft
C) 61.28 ft
D) 68.55 ft

B). 58.27 ft

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;
