Answer

y = 2x 

Explanation
The first thing is to find the gradient of the line.

Gradient = Δy/Δx
               = (4--2)/(2--1)
               = 6/3
                = 2


Now a general point (x, y) and one of thegiven points.

(y - 4)/(x - 2) = 2
y - 4 = 2(x  - 2)
y = 2x - 4 + 4
y = 2x + 0

y = 2x

An airline knows that on average about 5 percent of the people who make reservations on a certain flight will not show up. Conse
kolbaska11 [484]

Answer:

Probability that there will be a seat available for every passenger who shows up is 50/50 or 49/50

Step-by-step explanation:

Since it is known that 5percent of people who make reservations would not show up.

Therefore 5% of 52 sold ticket is

5/100 x 52 = 2.6

That is 2 or 3 people who make reservations would not show up.

Which means 52 - 2 or 52 - 3 people would show up

50 or 49 people would show up

Since the flight can hold just 50 people

The probability that everyone that shows up would have a seat is therefore =

50/ 50 or 49/50
