Answer:
s ≤ -18
Step-by-step explanation:
Multiply both sides of the inequality by -3. Since the multiplier is negative, you need to reverse the comparison symbol.
(-3)(-s/3) ≤ (-3)(6)
s ≤ -18
_____
If you multiply by a positive number, you don't need to reverse the symbol. Hence multiplying by 3 gives ...
-s ≥ 18
You can now add s to both sides:
0 ≥ 18 + s
and subtract 18 from both sides:
-18 ≥ s
Of course, this is the same relationship as ...
s ≤ -18
You first work out the mean then for each number subtract the mean and square the result then work out the mean of those squared differences and take the square rot of that and you're done :)

Surface area of cube = 6•s²
= 6 x 5²
= 6 x 25
= 150cm²
The number of ways a teacher can create a seating chart is 25!
<u>Explanation:</u>
Given:
Number of students = 25
Number of chairs = 25
Number of seating chart = ?
The number of seating arrangement would be 25! as there is no repetition of a student occupying the seat.
Therefore, the number of ways a teacher can create a seating chart is 25!
