What percent of 13.6 is 34?

1 answer:

4 0

So basically you are trying to find X×13.6=34 and you have to solve for X. To find the answer divide 13.6 from both sides of the equation to leave X by it self. You should get 2.5 as the answer.

X = 352.3 [your work is correct]

then the perimeter would be 352.3 + 352.3 + 280 + 280 = 1,264.55

A tour operator has a bus that can accommodate 20 tourists. The operator knows that tourists may not show up, so he sells 21 tic

Answer:

The expected revenue of the tour operator is 985.

Step-by-step explanation:

There are two outcomes:

Either less than 21 tourists show up and the operator does not have to pay anything. Or 21 tourists show up and the operator has to repay 100.

Anyways, initially he gets the price of all the tickets sold. That is 21 each at 50, so $R = 21*50 = 1050$ .

Then, we need to find the probability that all of the 21 tourists show up. In this case, we have to subtract 100 from the revenue.

Each tourist has a 0.02 probability of not showing up. This means that each has a 1-0.02 = 0.98 probability of showing up. So the probability P that all 21 tourists show up is $P = (0.98)^{21} = 0.6542$ .
