Ah, probability. A family favourite(In my case)

Answer: 1/4 (8/32 simplified)

Step-by-step explanation:

To answer the question, first let's find out how many green and red washcloths there are.(w representing white, g representing green, and r representing red)

There are twice as many g washcloths as w washcloths, so we multiply 4x2 and get eight g washcloths.

Now that we've found out how many g washcloths are there we can multiply 8x2 to get 16 r washcloths.

Now we add them all of to get 32 total wash cloths, and the probability can be shown as 8/32 simplified as 1/4

Which transformation of Figure A results in Figure A' ?
MariettaO [177]

Option B: a counterclockwise rotation of 90° about the origin

Explanation:

From the graph, we can see the coordinates of the figure A are (0,2), (-1,6) and (-4,4)

The coordinates of the figure A' are (-2,0), (-6,-1) and (-4,-4)

<u>Option B: a counterclockwise rotation of 90° about the origin </u>

The transformation rule for a coordinate to reflect a counterclockwise rotation of 90° about the origin  is given by

(x,y)\implies (-y,x)

Let us substitute the coordinates of the figure A

Thus, we have,

(0,2)\implies(-2,0)

(-1,6)\implies (-6,-1)

(-4,4)\implies(-4,-4)

Thus, the resulting coordinates are equivalent to the coordinates of the figure A'.

Therefore, the figure is a counterclockwise rotation of 90° about the origin .

Hence, Option B is the correct answer.
