Apopular resort hotel has 300 rooms and is usually fully booked about 7% of the time a reservation is cancelled before the 6: 00 pm deadline with no penalty. what is the probability that at least 285 rooms will be occipied? use the binomial distribution to find the exact value and the normal approximation to the binomial and compare your answers.

467answer:

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
