Answer:
It is the third option: (10C1) (20C1( / 50C2.
Step-by-step explanation:
The number of ways of selecting 2 marbles = the number of combination of any 2 marbles in the 50 marbles in the bag and this is 50C2. It is combinations because the order of drawing the marbles does not matter.
The number of combinations of one being red and the other blue = 10C1 times 20C1.
So the answer is (10C1) (20C1( / 50C2.
Answer:
A trapezoid can never be a kite.
Step-by-step explanation:
A trapezoid is a quadrilateral with exactly one pair of opposite parallel sides.
On the other hand, a kite is a quadrilateral with two pair of adjacent equal sides. It could be divided into two isosceles triangles.
So, a trapezium can never be a kite, because if a trapezium becomes a kite, it will never have a pair of opposite parallel sides.
Inversely, a kite can never be a trapezoid, because then it will never have adjacent pair of equal sides. Even if it does, then there would be two pairs of apposite parallel sides which is not the property of a trapezoid.
I've seen this question before and it's word for word
Answer:
y+1/2-2y-1/2=4
y-2y=4
-y=4
y=-4
Let me know if this helps!
Answer:
I believe the period is 1. Because if it was y= sin2 (2(x-1/2) then the period would be 2.
