Suppose that a restaurant chain claims that its bottles of ketchup contain 24 ounces of ketchup on average, with a standard deviation of 0.4 ounces. if you took a sample of the 49 bottles of ketchup what would be the approximate 95% confidence interval for a mean number of ounces of ketchup per bottle in the sample?
it is 5in
answer: 7(3m - 7n)
factor each term then see what value(s) they have in common:
21m - 49n
3 · 7 · m 7 · 7 · n
both terms have a 7 in common. what is left over after removing the 7?
gcf: 7 leftovers: 3m and 7n
factored form of expression is: 7(3m - 7n)
answer: 270÷90=3=30% have and 70% don't have a computer.
