Joe drew a diagram of a window as shown below. The window is formed by a square and a semicircle. The area of the square portion of the window is shown in square inches on the diagram. One side of the square measures 28 inches
What is the total area of the window rounded to the nearest whole number? Use 3.14 for me

1; 35 is the ratio

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;

a c
