Naddika [18.5K]

Answer:

The expected revenue of an airline ticket sold by this travel website is $408

For the revenues per ticket we have;

airline A; 600

airline B; 360

For the probability of choosing the airlines we have;

airline A; 20% = 0.2

airline B; 80% = 0.8

sThe number of users on a social networking site was 45 thousand in February when theyofficially went public, and grew to 60 tho

svetoff [14.1K]

Given:

No of users in February is 45,000 and in october its 60,000.

$P=45000(\frac{4}{3})^{(\frac{3}{2})^t}$

t=2

$P=45000(\frac{4}{3})^3$ $P=45000(\frac{64}{27})$ $P=5000(\frac{64}{3})$ $P=106666.6667$

Therefore, approximate no of users after 2 years is 106667.
