Permutations of 9 flower pots taken 4 at a time:
nPr = 9P4 = 3,024 - displays possible when order of flower pots matters.
I hope this helps
I at least think what this is asking.
U se the midpoint formula to find the midpoint of the line segment.
(5/2,5) or (5,5/2) it’s one of them .gotta be I’m pretty sure it’s (5/2,5)
<span>Which shows the elements of the set of whole number multiples of four less than 21?
The multiples of 4 are 4, 8, 12, 16, 20, 24, 28,...
Then, the set of the multiples of four less than 21 is {4, 8, 12, 16, 20}
A: {1, 2, 3, 4, 5}
B: {4, 8, 12, 16, 20}
C: all real numbers
D: null set
Which shows the set(s) the number 2.77 is an element of?
2.77 is a real number, it is not a natural number, and it is not a whole number.
A: real numbers
B: real numbers and natural numbers
C: natural numbers and whole numbers
D: null set
Given sets:
D = {5, 6, 7, 8, 9, 10}, E = {1, 3, 5, 7, 9, 11}, F = {3, 6, 9, 12}
What is D n E?
I believe the question is what is D ∩ E, which is the elements that are as much in D as in E. This is {5,7,9}
A: {1, 3, 5, 6, 7, 8, 9, 10, 11}
B: {5, 7, 9}
C: {9}
D: null set</span>
