Answer:

C. In y^2-y=6, 6 should have been subtracted on both sides first.

Step-by-step explanation:

It is a quadratic equation so you subtract the 6 and create

y^2-y-6=0

Then you factor it to:

(y-3)(y+2)=0

The solutions then are:

y-3=0, y=3 and y+2=0, y=-2

An urn contains balls numbered 1 through 20. A ball is chosen, returned to the urn, and a second ball is chosen. What is the pro
stira [4]
<h2>Answer:</h2>

The probability is:

                   \dfrac{1}{400}

<h2>Step-by-step explanation:</h2>

It is given that:

An urn contains balls numbered 1 through 20.

A ball is chosen, returned to the urn, and a second ball is chosen.

This means that this is a case of a replacement.

Hence, one of the event is independent of the other.

Now we know that the probability to get a particular number of ball is:

                  \dfrac{1}{20}

( Since, there are total 20 balls and a ball of one particular number is just unique )

i.e. \text{Probability of getting a 8}=\dfrac{1}{20}

Hence, the probability that the first and second balls will be a 8 is:

=\dfrac{1}{20}\times \dfrac{1}{20}\\\\\\=\dfrac{1}{400}
