Answer:
750 sheets
Step-by-step explanation:
2.5 kilograms=2.5*1000=2500 grams
2500/40=62.5 stacks-of-12-papers
62.5*12=750 sheets of paper
To check our work:
Let's set x as the weight of one sheet of paper.
12x=40 grams, x= 3 1/3 (three and one thirds) grams
3 and 1/3 *750= 2500 grams
2500 grams=2.5 kilograms
x³-6x²+11x-6
put x=1
1³-6×1²+11×1-6=1-6=11-6=0
by synthetic division
1| 1 -6 11 -6
| 1 -5 6
|----------------
| 1 -5 6 |0
x²-5x+6=0
x²-2x-3x+6=0
x(x-2)-3(x-2)=0
(x-2)(x-3)=0
x=1
x-1=0
so x³-6x²+11x-6=(x-1)(x-2)(x-3)
Mean= 10
Mean= Total value of data/Number of datas given
=3+2+26+9/4
=40/4
=10
B={x|x is an even whole no less than 9}
Now
