An architect is drawing a blueprint for a house. He uses a scale of 1/2in. = 1 1/2ft. If the kitchen is 5 1/2 inches long on the blueprint, how long will it be in the actual house? The kitchen will be feet long.

based on context clues you gave i'm assuming the answer would be c.

1.true 2.false? ? i think. .

step-by-step explanation:

answer:

your answer is: c. 196 7/8 in^3.

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;
