Answer:
I have it in above pic hope it
As points, x-intercepts take the form

, so to find the intercepts we can set

and solve for

.

From the first equation alone, we already know that

is a solution, which means one intercept is

.
The second equation gives

so that the second intercept occurs at

.
So if

and

, we have

, giving C as the answer.
Answer: The answer is 1,600.
Explanation: since her back yard is a square that means it has 4 sides, and her yard is 400 sq ft. So you multiply 400 by 4 which equals 1,600. I haven’t done this in a long time so I’m not positive. But that should be it.
6 minutes, 3 minutes, 5 minutes
we need to find the lowest common multiple of these numbers.
6 : 6,12,18,24,30
3: 3,6,9,12,15,18,21,24,27,30
5: 5,10,15,20,25,30
30 is ur lowest common multiple...so they will all meet at the starting point in 30 minutes...hooray for piggly, piglet, and wiggly :)
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
.
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
.
So, the expected revenue of the tour operator is

Rounded up, the expected revenue of the tour operator is 985.
