Jodi is cutting out pieces of paper that measure 8 inches by 11 inches from a
larger sheet of paper that has an area of
1,000 square inches

a. What is the area of each piece of paper
that Jodi is cutting out?

b. What is the greatest possible number of
pieces of paper that Jodi can cut out of
the larger sheet?

The answer to part a is 88 inches

The answer to part b is 10inches by 90 inches

Step-by-step explanation:

11*8 =88

90*10=900 inches

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;
