Answer:

3/10

Step-by-step explanation:

8 blue marbles and 12 yellow marbles.  = 20 marbles

P( yellow) = yellow/total =12/20 =3/5

P(plastic) =1/2

P(yellow, plastic) = 3/5 * 1/2 = 3/10

Is the ordered pair (-3, 16) a solution for y=-3x + 7?
8_murik_8 [283]

Answer: Yes

Step-by-step explanation:

(-3, 16) split into place would give you 16= -3-3 + 7. A negative times a negative is always a positive number so, -3 x -3 = 9, 9+7=16

The kind of transformation the quadrilateral underwent is 180° rotation about the origin and the new vertex of Q is (4,5).

<h3>What is transformation of plane shapes?</h3>

Transformation is the change in the coordinates of the vertices that make up a plane shape.

This can be done either by translation, reflection or rotation.

Analysis:

since the x and y coordinates of P is the opposite of the coordinates of p' then there is a 180° rotation about the origin.

If vertex Q is (-4, -5), then Q' is the opposite which is (4, 5 )

In conclusion, the transformation is a 180° rotation and the coordinates of Q' are (4, 5).
