Aset of 10 determinations, by a method devised by the chemist karl fischer, of the percentage of water in a methanol solution yielded the following data. 50, .55, .53, .56, .54, .57, .52, .60, .55, .58

assuming normality, use these data to give a 95 percent confidence interval for the actual percentage.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

x=30

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

i think the amount would be $140.62
