Answer:
(d) n > -4
Step-by-step explanation:
Divide by the coefficient of n. Because that is division by a <em>negative</em> number, reverse the inequality symbol.
n > (16/-4)
n > -4
It is 6 because 6x6x6=216
Answer:
The number of ways is equal to 
Step-by-step explanation:
The multiplication principle states that If a first experiment can happen in n1 ways, then a second experiment can happen in n2 ways ... and finally a i-experiment can happen in ni ways therefore the total ways in which the whole experiment can occur are
n1 x n2 x ... x ni
Also, given n-elements in which we want to put them in a row, the total ways to do this are n! that is n-factorial.
For example : We want to put 4 different objects in a row.
The total ways to do this are
ways.
Using the multiplication principle and the n-factorial number :
The number of ways to put all 40 in a row for a picture, with all 12 sophomores on the left,all 8 juniors in the middle, and all 20 seniors on the right are : The total ways to put all 12 sophomores in a row multiply by the ways to put the 8 juniors in a row and finally multiply by the total ways to put all 20 senior in a row ⇒ 
24-24=0
And we have 24-28. so after 24-24=0 we still have to subtract 4 more.
0-4=-4
The answer is therefore -4
Hmmm im on the same question so i think its this
