Answer:
Research also confirms that incisions carried out with obsidian produce narrower scars and fewer inflammatory cells. This is because on cellular level, obsidian knife cuts between cells rather than tearing it in case of a steel knife, hence, a sharper cut allows the wound to heal more easily with negligible scarring.
Answer:
You keep them if you test 3 and all pass.
There are 18 good ones and 6 bad (making 24)
Chance of first passing is 18/24
If it passes, there are now one less good and one less total.
Chance of second passing is 17/23
If it passes, there are now one less good and one less total.
Chance of second passing is 16/22
Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).
So probability all are ok is 0.4
Thus probability you find at least one bad one is 0.6
Hope this helps you out!
<span>A) 2x + 4y = 14
B) 4x + y = 20
If you multiply equation A by -2, then when the equations are added, the x will be eliminated.
The solutions are:
X = 4.714285714285714
Y = 1.1428571428571428

Jenny has the most. That is because Jenny has more than Marcy and Laura.
Answer:
The total cost charged by the two companies will be the same for 10 square yards of carpeting .
Step-by-step explanation:
Let us assume that the number of square yards for carpeting used be x.
Let us assume that the total cost of the charged by the companies be y.
As given
Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100.
Than the equation becomes
y = 22x + 100
As given
City Carpets charges $25 per square yard for the same carpeting, and an additional installation fee of $70.
Than the equation becomes
y = 25x + 70
Than the two equations are
y = 22x + 100 and y = 25x + 70
Than compare the two equations are
22x + 100 = 25x + 70
25x - 22x = 100 - 70
3x = 30
x = 10 square yards .
Therefore the total cost charged by the two companies will be the same for 10 square yards of carpeting .
