Archer wants to find the average number of the 25,000 passengers on a national airline that check one item of luggage. He randomly selects 1,000 passengers in his home state of North Carolina who flew in the past year, and he found that 70% of the
passengers checked one item of luggage. What assumption can be made regarding the proportion of all the passengers who check
one item of luggage?

An assumption can be made that 70% of 25000 passengers will check one item of luggage

Step-by-step explanation:

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
