42. The streets of Millston are laid out like a grid, with each square block being the same size. The distance from the movie theater to a restaurant is mile
along Cabot Street. If there are exactly 4 blocks between the two locations,
how long is each block?

A 1/8
B 1/6
C 4/2
D 8/1​

which expression represents the approximate length of bc?

step-by-step explanation:

12.5 feet

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;
