Divide the following polynomial by 3.c. 27x²y – 15xy
1 answer:
Answer:
Step-by-step explanation:
Split it up like this to make it easier to work with:
Since the only thing in the denominator of those fractions is a 3, we can only divide the 27 by 3, not the x or y terms. Same thing with the second fraction. 27 divided by 3 is 9 and 15 divided by 3 is 5, so
is the solution. It is not completely simplified, but that isn't what you asked for, so this should suffice as the answer.

Answer:
From inspection of the diagram, we can see that the spinner is divided into <u>4 equal parts</u>, where 3 parts are red and 1 part is yellow.
Therefore,
<u>Multiplication Rule for Independent Events</u>
For independent events A and B:
Therefore,
Ari is incorrect. The spinner is divided into 4 parts, where only one part is yellow. Therefore, the probability of spinning a yellow is 1/4. As the events are independent, the Multiplication Rule should be used to calculate the probability of spinning 2 yellows. So the probability of spinning 2 yellows is 1/4 x 1/4 = 1/16.
