The steepest line possible is a vertical line. Its slope is bigger than any
possible number you can think of, because it can change its height by
any amount in zero time. Its slope is 'undefined', meaning that there's
no number that can describe it. Some people would say it's 'infinity',
but that's not a number.
Probbality=desired outcomes/total possible outcomes
so you and 2 friends makes 3 people
you each order a differnt topping
so
7/14 or 1/2 of them are meat on first try
then, 1 less topping, so 6/14 or 3/7 are meat for 2nd peson
then 1 less topping so 5/14 are meat for 3rd person
1/2 times 3/7 times 5/14=15/196
probablity will be 15/196 or about 7.65%
Answers:
1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.
1B. Idon't know how to graph it here sorry.
1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.
1D. I just did
A quadrilateral is a kite if the diagonals are:
i) perpendicular
ii) bisect each other
iii) not equal ( together with conditions i and ii this would make the quadrilateral a square)
Another definition of the kite is :
a quadrilateral with 2 pairs of equal adjacent sides.
Let's check the choices one by one:
A. <span>∠M is a right angle and MK bisects ∠LMJ.
according to these, ML and MJ may well be not equal...
</span><span>B. LM = JM = 3 and JK = LK = √17.
</span>
this makes the quadrilateral a kite.
<span>C. MK intersects LJ at its midpoint
</span>
if they are not perpendicular, the quadrilateral is not a kite.
<span>D. The slope of MK is –1 and the slope of LJ is 1.
this only means that MK and LJ are perpendicular, but not whether they bisect each other,
Answer: only B</span>
