1/32 because 1/4 is the probability for the first one and then 1/8 for the next one. 4 times 8 = 32  so there is a 1 in 32 chance

<h2>Answer:</h2>

The probability that you will spin "East" and "1" is:

                            \dfrac{3}{32}

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

As we know that the spinning of the first wheel is independent of the outcome of the spinning of the second wheel.

Let A denote the event of East.

B denote the event of 1 .

Let P denote the probability of an event.

A∩B denote the event of East and 1.

We are asked to find P(A∩B)

We know that:

    P(A∩B)=P(A)×P(B)

( When the events A and B are independent )

From the image we have:

P(A)=1/4

and P(B)=3/8

( Since there are 3 '1' in the spinner out of total 8 outcomes)

Hence we get:

    P(A\bigcap B)=P(A)\times P(B)\\\\\\P(A\bigcap B)=\dfrac{1}{4}\times \dfrac{3}{8}\\\\\\P(A\bigcap B)=\dfrac{3}{32}

What is 2xy-3yz+5+2yz-xy
melomori [17]

To simplify this expression, we are going to combine like terms.


First, we can see that we have two terms with the variables xy being multiplied together, 2xy and -xy. Together, these add to xy, so our expression is now:

xy - 3yz + 5 + 2yz


We also have two terms with yz, -3yz and 2yz. Together, these add to -yz, so our expression is now:

xy - yz + 5


Our final expression is xy - yz + 5.

Find the value of x ?
RUDIKE [14]

Answer:

x = 50

Step-by-step explanation:

add all terms and set sum equal to 360

the 'hint' of (n-2)180 determines how many degrees there are inside the polygon; if 'n' equals the number of sides and the polygon has 4 sides then sum of interior angles is (4-2)180 or 2x180 which is 360

x + 10 + 3x + x + 2x = 360

combine like terms to get:  7x + 10 = 360

                                             7x = 350

                                              x = 50

Hey how do you get from standard form to vertex form?
vlabodo [156]

Explanation:

Conversion of a quadratic equation from standard form to vertex form is done by completing the square method.

Assume the quadratic equation to be \mathbf{ax^{2}+bx+c=0} where x is the variable.

Completing the square method is as follows:

  1. send the constant term to other side of equal                 \mathbf{ax^{2}+bx=-c}
  2. divide the whole equation be coefficient of \mathbf{x^{2}}, this will give     \mathbf{x^{2}+\frac{b}{a}x=- \frac{c}{a}}
  3. add \mathbf{(\frac{b}{2a})^{2}} to both side of equality                                   \mathbf{x^{2}+2\times\frac{b}{2a}x+\frac{b}{2a}^{2}=-\frac{c}{a}+\frac{b}{2a}^{2}}
  4. Make one fraction on the right side and compress the expression on the left side                                                                          \mathbf{(x+\frac{b}{2a})^{2}=\frac{b^{2}-4ac}{4a^{2}}}
  5. rearrange the terms will give the vertex form of standard quadratic equation                                                                 \mathbf{a(x+\frac{b}{2a})^{2}-\frac{b^{2}-4ac}{4a}=0}

Follow the above procedure will give the vertex form.

(NOTE : you must know that \mathbf{(x+a)^{2}=x^{2}+2ax+a^{2}}. Use this equation in transforming the equation from step 3 to step 4)
