Answer:
32760 different schedules are possible.
Step-by-step explanation:
The order is important.
For example
Prague on Monday, Berlin on Tuesday, Liverpool on Wednesday and Athens on Thursday is a different schedule than Berlin on Monday, Prague on Tuesday, Liverpool on Wednesday and Athens on Thursday.
So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
How many different schedules are possible?
Choose 4 cities among a set of 15. So
32760 different schedules are possible.
Hello there!
The correct answer is B. Why? Well, we cannot choose A, because we don't have a multiplication sign. We cannot choose C because we also don't have a multiplication sign. However, since we have a PLUS sign and a Subtraction sign, we can say that the correct answer is option B.
3x + 1 < -2x + 8
We wanna start by subtracting 1 on both sides
3x + 1 - 1 < -2x + 8 - 1
3x < -2x + 7
Add 2x on both sides
3x + 2x < -2x + 7 + 2x
5x < 7
x < 7/5

Answer:
192
Step-by-step explanation:
There are a total of 15 marbles . When the lavender is left out 14 remain.
Using combinations we find that each of the four color marbles can be chosen in the following way.
2C1*4C1*4C1*6C1= 2*4*4*6= 192
We select one of the two red marbles , one of the four green marbles, one of the four yellow marbles, one of the 6 orange marbles leaving the lavender out.. We apply combinations and then multiply to get the answer.
