Step-by-step explanation:
A polyhedron include cube ,prism or pyramid while non polyhedron are sphere, cone and cylinder because they have side that aren't polygon. a prism is a polyhedron with two congruent base ,in parallel planes and the lateral sides are rectangle
Hey!
Grape over total: 
After he drinks 1, there will be 1 less. That means it will be over 11
Orange over total: 
Now multiply the fractions
That means the probability is: 
Good luck and hope this helps! :)
Answer:
Let C be the cost for the people staying
if n <= 2 ; C = $125
If n >2 ; C = $125 + $25 * (n-2)
Step-by-step explanation:
If the number of people is more than two, we need to add $25 for each of them.
Since n will be the number of people staying, we need to make sure that we substract two from this term to avoid overcharging the guests when there is less than two people.
So
(n-2) is the term that should be multiplied by a factor of 25.
Answer:
Option B
Step-by-step explanation:
Looking at the options, option B is correct because when multiplying it by matrix A, it yields the matrix AB as follows;
First row of A multiplied by first column of matrix in option D;
(1 × -1) + (0 × 0) + (0 × 0) = -1 which corresponds to the first number on the first row of Matrix AB
Since majority of matrix AB are zero, I will just prove the ones that are not zero.
Thus;
Second row of matrix A is multiplied by second column of matrix in option D;
(0 × 0) + (-1 × -1) + (0 × 0) = 1 which is same as 2nd number on second row in matrix AB
Lastly, third row of matrix A is multiplied by third column of matrix in option D;
(0 × 0) + (0 × 0) + (1 × -1) = -1 which is same as third number in third row in matrix AB
