Suppose 1/3 of the next 3000 passengers have a frequent flyer account. remember that you already have 110 passengers with frequent flyer accounts from the last question. find the percentage of observed passengers (3339 total) with a frequent flyer account.

Percentage of observed passengers with a frequent flyer account = 33% approximately.

Step-by-step explanation:

It is given that 1/3 of the next 3000 passengers have a frequent flyer account.

So, = 1000 passengers have a frequent flyer account.

It is also given that we already have 110 passengers with frequent flyer accounts from the last question.

So, total number of passengers who have flyer account = 1000 + 110 = 1110

It is given that the total number of passengers = 3339

Hence, the percentage of passengers with a flyer account =

= 33% approximately

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
