There is no question it is just a statement.
Answer:
This can be done in 3645 ways
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this problem, we have that:
1 Beethoven symphony, from a set of 9.
1 Mozart concerto, from a set of 27.
1 string quartets, from a set of 15.
So
This can be done in 3645 ways
Answer:
Option 2 (Graph B)
Step-by-step explanation:
x ≤ ⁵/4 or x ≥ ⁵/2 represents a compound inequality containing the union of two statements. Either of the statements makes the compound inequality true.
On a graph, the small "o" indicating the start of the value of x would be full, this means ⁵/4 and ⁵/2 are included in the solutions.
Therefore, the correct graph in option 2 (Graph B), where the arrow goes from between 1 and 1.5 to your left, and the other arrow goes from 2.5 to your right.
