Atravel website sells tickets to a city for two airlines. among those buying tickets, 20% fly airline a, and 80% fly airline b. if the price of a ticket is $600 for airline a and $360 for airline b, what is the expected revenue of an airline ticket sold by this travel website? (note: airline a has much more desirable departure times than airline b, so it charges more.)

$360

$408

$500

$600

The expected revenue of an airline ticket sold by the travel website is:

                         $ 408

Step-by-step explanation:

It is given that:

20% fly airline A.

and and 80% fly airline B.

Also,  If the price of a ticket is $600 for airline A and $360 for airline B.

The expected value is calculated by:

where p denote the probability of an event.

and P denotes the price of the ticket.

Clearly from the data we have:

Hence, we calculate expected revenue as follows:

answer: the equation matches the regression

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
