Choose the option that best completes the statement below. In finding the number of permutations for a given number of items, _____. A) the number of permutations is limited by the number of items which are alike.
B) it doesn’t matter if some of them are indistinguishable .
C) the number of permutations is determined by the number of items that don’t repeat.
D) the number of permutations isn’t dependent on the items that repeat.

Answer 1

Answer: Let’s look at the permutations of the letters “ABC.” We can write the letters in any of the following ways:
ABC
ACB
BAC
BCA
CBA
CAB
Since there are 3 choices for the first spot, two for the next and 1 for the last we end up with (3)(2)(1) = 6 permutations. Using the symbolism of permutations we have: $3 P_(3)=(3)(2)(1)=6$ . Note that the first 3 should also be small and low like the second one but I couldn’t get that to look right.

Now let’s see how this changes if the letters are AAB. Since the two As are identical, we end up with fewer permutations.
AAB
ABA
BAA
To make the point a bit better let’s think of one A are regular and one as bold A.
ABA and ABA look different now because we used bold for one of the As but if we don’t do this we see that these are actual the same. If they represented a word they would be the same exact word.

So in this case the formula would be $(3 P_(3) )/(2!)= ((3)(2)(1))/((2)(1))= (6)/(2)=3$ . We use 2! In the denominator because there are 2 repeating letters. If there were three we would use 3!

Hopefully, this is enough to let you see that the answer is A. The number of permutations is limited by the number of items that are identical.

15.Identify the coordinates of point C after a translation with rule (x + 3, y 2).C' = (5, 7)

C' = (6, 6)

C' = (2, 0)

C' = (0, 2)

Answers

Since the original coordinates are (-3,4), you can start finding the prime coordinates by adding 3 to the x-value, and subtracting 2 from the y-value. This will get you (-3+3, 4-2) This will come out to (-0, 2), so your answer will be...

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The inequality will like this....

$x\geq53$

because if it says at least 53 people buy food from the food truck that means it could be 53 people or more.

Now for the graph it will be the one with the closed circle and the arrow pointing to the right.

The line is supposed to resemble how many people buy food from the food truck.

So the meaning of the closed circle is that the 53 is included within the possiblities and the arrow would show how much could be there since it said at least 53 people so there could be more.

Answer:

The answer will the closed circle with an arrow to the right on the 53

Explanation:

The closed circle with the arrow pointing left means equal to or greater than blank

It is at least 53 people, meaning it could be 53, 54, 55, or more forever
