Mitchell takes a 7­inch by 5­inch rectangle of fabric and cuts from one
corner of the piece of fabric to the
diagonally opposite corner. Now
Mitchell has two equally sized triangles
of fabric. What is the perimeter of each
triangle? If necessary, round your
answer to the nearest tenth.

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;
