An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, a
gulaghasi [49]

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022

What are the key features of a graph of a quadratic equation with only complex solutions
dybincka [34]

Answer:

If  D< 0, the roots of the quadratic equation will b complex.

Step-by-step explanation:

Let ax^{2}  + bx + c =0 is the given quadratic equation.

So, if the Discriminant (D) = b^{2}  - 4ac  < 0, the the equation will have only complex solutions.

Complex roots are represented in the form of (x \pm iy)

1.  <u> x represents the X axis (real) co ordinate,</u>

    <u>y represents the Y axis (imaginary) coordinate</u>

<u />

<u />

2. Also, the graph of the with equation  D < 0  NEVER CROSSES the X - axis, as there are no real roots of the equation, only complex roots.

3. Here. roots are always identical but are opposite in signs. Such pair or roots with opposite sign are called CONJUGATE PAIRS.

8x – 10 = 3x – 10 + 7x
stira [4]

Answer:

x= 0

Step-by-step explanation:

Let's first simplify the equation to make the PEMDAS process easier.

8x-10=3x-10+7x

8x-10=10x-10

Now lets start the subtracting and dividing process.

8x=10x

0=2x

0=x
