33.51 X 85% (0.85) = 28.48
Answer:
number 2 is C and number 3 is D
Step-by-step explanation:
820
Explanation: it is .82x (1,000/15,000)
The factorial ! just means we multiply by every natural number less that the value so
6! =6×5×4×3×2×1= 720
for permutations we use the formula n!/(n-r)!
so we have 8!/(8-5)!=8!/3!=8×7×6×5×4
for combinations s we have n!/(n-r)!r!
so we have 12!/(12-4)!4!=12!/8!4!=12×11×10×9/4×3×2=11×10×9/2=99×5
The equation has no solution
