Two groups of campers carry their water in reusable packs that come in three sizes. The table shows how many packs each
group carries. A medium water pack holds 1 liter more than a
small pack holds. A large pack holds 2 liters more than a small
pack. Do the two groups carry the same amount of water? If not,
which group carries more? Use w to represent the number of
liters of water a small pack can hold. Show your work.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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;
