1) The order of selection matters. Therefore we need to find the number of permutations of 11 members taken 3 at a time. 11P3 = 990 ways.
Answer choice B) is correct.
2)The order of selection matters. Therefore we need to find the number of permutations of 12 members taken 4 at a time. 12P4 = 11,880.
Answer choice C) is correct.
Answer:
tens
Step-by-step explanation:
-13>-5x+2>-28 subtract 2 from all expressions
-15>-5x>-30 divide each expression by -5
Be sure to reverse direction of signs when you divide/multiply by a negative value!
3<x<6
So the "graph" will be a infinitely high plane, or area, contained between the two vertical lines x=3 and x=6
You can to 7+2 or 6+3 or 5+4.
Im sorry , the second point , do u mean its a -4
