Dean uses a scale of 4 centimeters to 1 foot to draw the diagram. the actual length of kitchen island is 3 feet, and its width is 2 feet. the area of the scale diagram of the island is square centimeters. nextreset

3*4 = 12 cm

2*4 = 8 cm

 the island is drawn at  12 cm  long x 8 cm wide

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;

answer: c
